[00:00:32] This is True Crime Psychology and Personality, where we discuss the pathology behind some of the most horrific crimes and those who committed them from a scientifically informed perspective.

[00:00:47] I'm Dr. Todd Grande.

[00:00:49] I have a PhD in counselor education and supervision, and I'm a licensed professional counselor of mental health.

[00:00:55] Dr. Todd Grande, that's my YouTube channel.

[00:00:59] Today's question is, can I analyze the case of Christopher Greger?

[00:01:03] First, to look at the background of this case, move to the timeline of the crime, then offer my analysis.

[00:01:09] Christopher Greger was born on May 21, 1992, and lived in the state of New Jersey.

[00:01:15] He attended Monroe Township High School, where he was an all-state defensive lineman.

[00:01:20] After graduating, he briefly attended a university in Middletown, Connecticut.

[00:01:25] In November 2010, Christopher was arrested for allegedly stealing from a woman's room in a dormitory

[00:01:30] and attacking two male students who tried to stop him during his escape.

[00:01:35] He allegedly used his fists and elbows in the attack.

[00:01:40] In 2013, Christopher started working as a marketing intern in Florida.

[00:01:44] After that, he was a sales associate.

[00:01:47] In 2016, he earned a bachelor's degree in psychology from a different college

[00:01:51] and started working as a real estate agent in New Jersey.

[00:01:55] In June 2017, Christopher started working as a math teacher in Baltimore, Maryland.

[00:02:01] Between August 2017 and April 2018, he was charged with a number of offenses including assault,

[00:02:08] robbery, and destruction of public property.

[00:02:11] Starting in February 2018, Christopher worked as a real estate agent in New Jersey.

[00:02:16] In 2019, he earned a master's degree in secondary education and teaching.

[00:02:21] As far as romantic contact, Christopher became involved with a teenager named Brianna Mitchell-Lowe.

[00:02:27] On May 1, 2014, 17-year-old Brianna had a son named Corey Mitchell-Lowe.

[00:02:33] Christopher was the father, but he did not know that at the time.

[00:02:37] He only learned about this later when Brianna sought child support.

[00:02:40] From that point on, Christopher and Brianna shared joint custody.

[00:02:44] In March 2020, Christopher was awarded full custody of Corey

[00:02:48] because Brianna had difficulty regulating her intake of substances.

[00:02:52] Christopher lived in an apartment in Barnaget, New Jersey, and Brianna lived in Englishtown,

[00:02:57] which is about an hour north.

[00:02:59] There was a lot of tension between Christopher and Brianna,

[00:03:03] now moving to the timeline of the crime.

[00:03:05] On March 20, 2021, Christopher and his son entered the fitness center

[00:03:10] for the Atlantic Heights Apartment Complex.

[00:03:13] This is the apartment complex where Christopher lived.

[00:03:16] A surveillance camera captured their activity.

[00:03:19] Initially, Christopher was lifting weights as his son was on a treadmill.

[00:03:24] At some point, Christopher went over to the treadmill and increased the speed.

[00:03:28] Corey was unable to keep up and fell off the treadmill several times.

[00:03:32] Christopher could be seen picking Corey up and putting him back on the treadmill.

[00:03:37] After a few of the falls, Corey stood up on his own

[00:03:40] and tried to jump back onto the moving treadmill to continue running.

[00:03:44] He fell, slammed into the belt of the treadmill, and was thrown backward onto the floor.

[00:03:50] At one point during the sore deal, Christopher appeared to bite Corey's head.

[00:03:55] Corey sustained bruises during this incident.

[00:03:57] When his mother Brianna saw them, she filed an emergency order for custody,

[00:04:02] but it was denied on April 1, 2021.

[00:04:05] That same day, Brianna picked up Corey for scheduled visitation.

[00:04:09] She brought him to see a pediatrician.

[00:04:12] Eventually, Corey was evaluated in a hospital.

[00:04:15] He was discharged at 1 a.m., now on April 2.

[00:04:18] Brianna kept Corey that night and brought him back to Christopher at 9.03 a.m.

[00:04:24] At 3.48 p.m., still on April 2,

[00:04:27] Christopher brought Corey to the Southern Ocean Medical Center in Manahakan.

[00:04:32] He told medical providers that Corey woke up from a nap,

[00:04:35] slurring his words, stumbling, nauseated, and experiencing shortness of breath.

[00:04:41] As a CT scan was being administered, Corey started having seizures.

[00:04:45] Medical providers attempted to save his life, but they were not successful.

[00:04:50] Corey was pronounced dead at 5.03 p.m.

[00:04:53] Christopher did not wait around to see what would happen next.

[00:04:56] Rather, he left the hospital.

[00:04:58] He drove to Tennessee before returning to New Jersey.

[00:05:02] On the next day, April 3, an autopsy was performed on Corey's body.

[00:05:07] The medical examiner ruled that Corey's death was caused by blunt force injuries

[00:05:11] with cardiac and liver contusions, acute inflammation, and sepsis.

[00:05:16] At that time, the manner of death was ruled undetermined.

[00:05:20] On July 7, 2021, Christopher was arrested

[00:05:23] and charged with endangering the welfare of a child

[00:05:26] in relation to the Treadmill incident from March 20.

[00:05:29] Even though this was a serious charge, falling on the Treadmill did not appear to cause Corey's death.

[00:05:35] Christopher was released on bail.

[00:05:37] In September 2021, Corey's case was reviewed by a forensic pathologist.

[00:05:42] The pathologist believed that 4-12 hours prior to Corey's death,

[00:05:46] he sustained blunt impact injuries to the chest and abdomen

[00:05:50] with laceration of the heart, left pulmonary contusion,

[00:05:53] and laceration and contusion of the liver.

[00:05:57] On March 3, 2022, Corey's manner of death was ruled homicide.

[00:06:02] On March 9, Christopher Greger was arrested again

[00:06:05] and additionally charged with first-degree murder.

[00:06:08] The state claimed that he knowingly caused serious bodily injury

[00:06:12] resulting in the death of another.

[00:06:14] This time, Christopher was held without bail.

[00:06:18] The state put together their theory of the crime.

[00:06:20] It was fairly straightforward.

[00:06:22] They believed that Christopher severely beat Corey

[00:06:25] during the time he was alone with him on April 2, 2021.

[00:06:29] On April 30, 2024, over three years after Corey's death,

[00:06:34] Christopher's trial started.

[00:06:36] At the time I'm making this video, the trial has been going on for three days.

[00:06:41] Now moving to my analysis.

[00:06:43] Christopher Greger maintains his innocence.

[00:06:45] His defense attorney argued that the Treadmill incident is completely separate from Corey's death.

[00:06:51] Corey died as a result of sepsis caused by pneumonia

[00:06:54] and it had nothing to do with Christopher's behavior.

[00:06:58] The state, of course, disagrees.

[00:07:00] They believe it is exceedingly clear that Christopher murdered his son.

[00:07:05] This brings me to the question, is Christopher guilty of murder?

[00:07:09] Let's take a look at the evidence both foreign against the idea that he is guilty

[00:07:13] starting with the inculcatory factors.

[00:07:15] On April 2, 2021, Christopher took Corey to a hospital where Corey died.

[00:07:20] No one else was with Corey and the hour is leading up to his death.

[00:07:24] An expert for the state said that Corey died from blunt impact injuries.

[00:07:29] Christopher left the hospital and drove to Tennessee rather than waiting.

[00:07:34] About two weeks before Corey died, surveillance video captured Christopher mistreating Corey in the Treadmill incident.

[00:07:41] Corey told a medical provider that his father forced him to run on the Treadmill because he was too fat.

[00:07:48] The police said they could smell cleaned or dried vomit in Corey's bedroom in Christopher's apartment.

[00:07:54] On April 3, the day after Corey died, Brianna sent him a text message at 6.02 p.m.,

[00:07:59] saying that the police were looking for him.

[00:08:02] At 6.09 p.m., Christopher used his phone to search the internet for the term

[00:08:06] Can Your Phone Be Tracked in Airplane Mode?

[00:08:10] A minute later, he searched Can My Car Be Tracked and Will Redmarks Turn into Bruises?

[00:08:17] Christopher then sent a text message to his parents saying he would not be back for a while

[00:08:22] and asked if they would take care of his dog.

[00:08:25] On April 4, at 9.58 p.m., Christopher searched, quote,

[00:08:29] there was a murder determined from an autopsy how long to file charges, unquote.

[00:08:35] At 10.21 a.m., he searched, quote,

[00:08:38] how long after an autopsy to file charges, unquote.

[00:08:42] At 12.17 p.m., Christopher sent a message to a woman on Tinder

[00:08:46] saying that he was going to see his brother in Los Angeles.

[00:08:50] In reality, Christopher was in Tennessee.

[00:08:52] He stayed there for one night before heading back to New Jersey.

[00:08:56] Brianna claimed that she reported many instances of mistreatment perpetrated by Christopher against Corey,

[00:09:02] but no one listened to her.

[00:09:04] Moving to the exculpatory factors,

[00:09:06] Christopher's defense indicated that experts would testify that Corey died from sepsis caused by pneumonia.

[00:09:13] As far as the other injuries observed on Corey,

[00:09:16] life-saving techniques used by medical providers could have been the cause.

[00:09:21] Even though the treadmill incident looks bad for Christopher,

[00:09:24] it seems clear that the injuries sustained during that incident did not lead to Corey's death.

[00:09:30] Corey was evaluated by medical providers after that incident.

[00:09:34] Based on the timeline, it is possible that the fatal injuries Corey sustained occurred before he was dropped off to Christopher.

[00:09:41] Corey was in a hospital being evaluated until 1 a.m., 1 April 2.

[00:09:46] He was with his mother at this time.

[00:09:49] She dropped him off to Christopher just after 9 a.m.

[00:09:52] Christopher brought Corey to a different hospital where Corey died just after 5 p.m.

[00:09:57] According to a forensic pathologist,

[00:09:59] the injuries that killed Corey occurred 4 to 12 hours prior to his death.

[00:10:04] This means that Corey was attacked sometime between 5 a.m. and 1 p.m.

[00:10:10] During the first four hours of that time range, Corey was with Brianna.

[00:10:15] Christopher's defense argued that when Brianna took her son to the hospital,

[00:10:19] she was told that he might have sepsis as a result of complications from pneumonia.

[00:10:23] Brianna chose to take him out of the facility against medical advice

[00:10:28] and took him to Christopher.

[00:10:30] If she was so worried about Christopher harming Corey, why did she do that?

[00:10:35] On the stand, Brianna admitted that she regularly used methamphetamine years earlier.

[00:10:40] Just before Corey died on April 2, Brianna texted her boyfriend

[00:10:44] and asked him to get her methamphetamine.

[00:10:48] She admitted that after Corey died,

[00:10:50] she threw bones, eggs, rocks, and dead fish at the house where Christopher's parents lived.

[00:10:57] When considering all the evidence in this case,

[00:10:59] do I think that Christopher Greger is guilty of murder?

[00:11:02] Yes, I believe he is guilty beyond a reasonable doubt.

[00:11:06] When considering the treadmill incident,

[00:11:08] it's reasonable to believe that Christopher regularly mistreated Corey.

[00:11:12] The alleged fatal violence perpetrated on April 2

[00:11:15] was probably just another attack in a long series.

[00:11:19] Christopher may not have intended to kill Corey,

[00:11:22] but he knew his actions could lead to death.

[00:11:24] There's no way to be sure about what a jury might do,

[00:11:27] but I would be surprised if Christopher was acquitted.

[00:11:30] When speaking about the treadmill incident,

[00:11:32] his defense attorney told the jury,

[00:11:34] you're not going to like him.

[00:11:36] At least on this point, the attorney's assessment is accurate.

[00:11:40] What do I think happened in this case?

[00:11:42] This is just a theory, my opinion.

[00:11:45] Christopher Greger is immature, impulsive, irresponsible, aggressive,

[00:11:49] vindictive, and sadistic.

[00:11:51] There are many reasons that Christopher allegedly mistreated Corey.

[00:11:55] For example, he wanted to teach Brianna a lesson.

[00:11:59] He was angry with her.

[00:12:01] It was his way of getting revenge on her.

[00:12:03] Or it's possible that Corey was a constant reminder of Brianna.

[00:12:07] Christopher saw Brianna in Corey

[00:12:10] like he realized that Corey had some of her traits.

[00:12:13] This made Christopher upset.

[00:12:15] He wanted to eradicate those traits from Corey.

[00:12:18] After allegedly murdering Corey,

[00:12:20] Christopher fled because he knew he was guilty.

[00:12:23] He searched for the term,

[00:12:25] there was a murder determined from an autopsy,

[00:12:27] how long to file charges,

[00:12:29] because he knew that he had committed murder.

[00:12:32] After Christopher was arrested,

[00:12:34] he was offered a plea bargain.

[00:12:36] The terms indicated that he would plead guilty

[00:12:38] to both the murder and the endangering charge

[00:12:41] in exchange for 30 years in prison.

[00:12:44] Normally in New Jersey,

[00:12:46] prisoners must serve 85% of their sentence.

[00:12:49] But the terms of this plea bargain indicated

[00:12:51] that Christopher would serve the entire 30-year term.

[00:12:55] There was no way to get released before 30 years.

[00:12:58] This meant that instead of being eligible for parole

[00:13:01] at the age of 57, which factors in the 85% rule,

[00:13:05] he would have been in prison until the age of 62.

[00:13:08] One can appreciate why Christopher would not be excited

[00:13:11] to spend 30 years in prison

[00:13:13] and worse yet, 30 years in New Jersey.

[00:13:15] But the plea bargain Christopher was offered

[00:13:17] was actually a good deal.

[00:13:19] The minimum sentence he is facing if convicted of murder

[00:13:22] is 30 years in prison.

[00:13:24] The maximum is life in prison.

[00:13:27] In addition, the expected sentence for the endangering charge

[00:13:30] is between 5 and 10 years.

[00:13:32] Rejecting the plea deal just doesn't make any sense at all

[00:13:35] and supports the theory that Christopher is living

[00:13:37] in a fantasy world

[00:13:39] where he can avoid all responsibility

[00:13:41] for his behavior.

[00:13:43] Now moving to my final thoughts.

[00:13:45] As I mentioned, Brianna said that she alerted the authorities

[00:13:48] many times about Christopher's bad behavior,

[00:13:51] but no one listened to her.

[00:13:53] It's possible that she was ignored because of her history

[00:13:55] of substance use or simply because she was involved

[00:13:58] in a custody dispute.

[00:14:00] It is not unusual for individuals in these types of disputes

[00:14:03] to lie about each other.

[00:14:05] The lesson learned in this case is how it's important

[00:14:07] for the authorities to investigate all allegations,

[00:14:10] even those made by people who may have an ulterior motive.

[00:14:14] One thing about this case is certain.

[00:14:17] The circumstances conspired in such a way

[00:14:19] that Corey did not have any chance of remaining safe.

[00:14:23] The treadmill incident is a metaphor for his impossible situation.

[00:14:28] No matter how fast he tried to run,

[00:14:30] there was no way to escape.
