The New Jersey dad accused of killing his 6-year-old son by forcing him through grueling treadmill workouts and beating him describing his child’s mother as a “special kind of dirtbag” just two days after the boy’s death.

Christopher Gregor, 31, was pulled over by police in Alcoa, Tennessee on April 4, 2021 – two days after his son, Corey Micciolo, died from blunt force injuries — for speeding in a construction zone.

The officers questioned Gregor about the bizarre route he had taken from New Jersey through Arkansas and then turning back in the wake of his huge loss, bodycam footage of the stop showed.

“If he didn’t have a drug addict mother, then he’d still be alive. That’s been going through my head this whole drive. She’s a special kind of dirtbag,” Gregor told one of the cops, referring to Corey’s mom, Breanna Micciolo.

When the cops asked about his son’s death, Gregor said the boy succumbed to what doctors thought was “internal bleeding,” according to the Asbury Park Press.

Gregor also told the cops he was arrested once before in New Jersey, when Micciolo’s family supposedly planted marijuana on him.

One of the officers suggested Gregor might have been trying to cross the border into Mexico.

“No, I mean, even if I was, I wouldn’t be headed in the direction I’m in,” Gregor insisted, adding he drove 20 hours from New Jersey to Arkansas before turning around and heading back north.

The cops then asked him why he suddenly stopped to pick up a female friend at the airport in Alcoa.

“She didn’t feel comfortable with me driving another 13 hours after I’ve driven so much already,” Gregor said. “I haven’t slept much, as you can imagine.”

In the beginning of the video, Gregor can be seen getting out of his car and putting his hands on the roof while the officers frisk him.

“I said, I don’t mind you guys searching my vehicle at all. There’s nothing that I’m hiding,” the former high school football star told the cops.

After having run his plate, the cops realize there is a flag for it in New Jersey. Gregor then asks the cops if there was a search warrant to sweep his vehicle.

“I don’t know about that. The state of New Jersey is run by Democrats. We have very little to do with them,” one of the officers chided.

“You and me both,” Gregor replied.

The former math teacher also bizarrely suggested that he might have brain damage from his former football days.

“I played football, so I might have CTE,” he told one of the cops, referring to the neurodegenerative brain condition that results from repeated head trauma.

The cops eventually let Gregor go, but took his car and cell phone to search.

Gregor, of Barnegat, was arrested on murder charges connected to Corey’s death in March 2022, after a medical examiner ruled that the child died from the result of ongoing abuse.

Gregor turned down a 30-year plea deal, and is currently on trial.

In addition to the murder charge, Gregor is also facing one count of child endangerment stemming from a March 2021 surveillance video that showed him forcing Corey to run on a treadmill despite the boy repeatedly falling down face-first.

A portion of the body camera video from the Tennessee traffic stop was played in court last week, but Superior Court Judge Guy P. Ryan ruled that the footage was inadmissible because it contained hearsay, the Asbury Park Press reported.

Assistant Ocean County prosecutor Jamie Schron, however, told Ryan the state will bring up Gregor’s statements in the video during cross-examination if he makes claims that contradict the footage, the outlet added.
