'Deadbeat dad's' mom breaks down in court as she reveals his furious phone call from the hospital after his son died

The mother of a New Jersey 'deadbeat dad' whose son died of alleged abuse broke down in court as she revealed the furious phone call she received from him at the hospital following the little boy's death. 

Christopher Gregor 31, is accused of forcing his six-year-old son, Corey Micciolo, to run on a treadmill because he was 'too fat'. The little boy died soon after from injuries sustained from the alleged abuse. 

On the sixth day of Gregor's trial his mother Carol Gregor took the stand to recall the moment she learned of Corey's death from her son.

Carol broke down as she described a phone call she received from Gregor at the hospital where her grandson had died. 

'Chris is hysterical,' she said - adding that he was furiously screaming 'what did she do to him' about the little boy's mother, Breanna Micciolo. 

Gregor's mother then chokes back tears as she describes the exact moment Gregor told her 'Corey passed'.

'So I call my husband I'm flipping out at the house,' she said, adding that she was hysterically screaming after receiving the devastating news of her grandson's death 

As Carol recounts her shock reaction to Corey's death from the stand, Gregor is seen as he breaks down in tears from where he sat in court. He wiped his tears away with a handkerchief as he cried. 

'I was so worried,' she said. 'He was so adamant that something happened when he (Corey) was with his mother.'

Carol then revealed how her younger son, Danny, was receiving threatening phone calls on their home phone as she and her husband drove to the hospital following the 'devastating' news. 

Later on in the trial, the prosecution fired at Gregor's mother for not recalling the timeline of the day when asked. She hit back 'I wasn't looking at a clock. I was hysterical that my grandson had just passed - I wasn't timing things.'

On the fifth day Christopher Gregor's murder trial, the New Jersey father spent much of testimony glaring at forensic pathologist Dr. Thomas Andrew, appearing emotional at times as he described the fatal injuries inflicted on his son Corey.

Andrew said that Corey, who died in April 2021, lost his life due to blunt force injuries to his chest and abdominals, lacerations and contusions on his liver, and a laceration to his heart. 

The pathologist ruled Corey had signs of 'stress cardiomyopathy', a heart condition caused by ongoing stress that he testified 'suggests there was ongoing physiological stress most likely due to mistreatment or abuse.'

Corey Micciolo, 6, died in 2021 after a year of alleged abuse, with a forensic pathologist ruling he died due to blunt force trauma 

In sickening CCTV video shown in Gregor's ongoing trial, Corey was seen continuously falling off the treadmill, while Gregor keeps lifting him up and putting him back on the machine 

Earlier in the trial, the court was shown shocking footage of Gregor forcing his son to run on a treadmill, and picking him up off the floor several times when he falls off the machine. 

The footage was taken in a New Jersey gym less than two weeks before Corey died, where he was rushed to hospital dazed and unconscious hours after he was dropped at his father's home by his mother. 

Corey's mother Breanna Micciolo - who also testified against Gregor last week - alleged that he had never even met his son until a year before his death, and Corey would routinely return home from his father's home with fresh cuts and bruises. 

Prosecutors alleged that Gregor showed a pattern of abuse for months before Corey was killed, with the forensic pathologist ruling that his cause of death was blunt force injuries that were administered 'by another person.' 

Andrew, who did not perform the autopsy but was enlisted to give his verdict soon after the 2021 death, offered horrific new details of the manner of the six-year-old's demise.

Corey's mother shared sickening images of the abuse she claims was inflicted by the father to social media, including black eyes and bruises across his body 

Corey would allegedly often return from his father's home with new bruises and injuries 

Beginning with a contusion below Corey's diaphragm, he said the boy suffered two significant injuries to his liver, including a laceration to the liver tissue that caused blood to pool on his pelvis. 

Andrew testified that Corey's body was also found to have a 'pulmonary contusion' to his lung causing internal bleeding, and several scalp contusions. 

Notably, Corey also suffered a fatal laceration 'near the tip' of his heart, Andrew said, which was exacerbated by 'chronic ongoing stress' in his life. 

'The immediate cause of death was blunt force injuries on the day he died,' the pathologist said. 'But stress cardiomyopathy suggests there was ongoing physiological stress, most likely due to mistreatment or abuse.'
