Talking to the New York Post, the victim's mother, Dorothy, said the couple had been arguing over his use of narcotics.

'At first, he didn't want any children,' she said.

'And when she found out she was pregnant, he said, "I hope you spit out a boy 'cause my track rec­ord sucks", because he has three girls.

'We would've known the sex of the baby in nine days, but the nine days are gonna be gone and she's gonna already be in the ground.'

The troubled couple lived together sporadically and Dorothy said Jackson 'had an issue' with angel dust - a powerful hallucinogenic.

Dorothy claimed Bridget spent her whole life dreaming of being a parent and that Jackson ripped that away from her.

She told the NYDP the suspected killer was put on opiates after knee surgery.

Dorothy said the drugs, which come legally in the form of codeine and morphine, are becoming the biggest killer drug on Staten Island.

'But it didn't kill him,' she added. 'It killed my baby, because my daughter's not here no more.'

Her daughter tried desperately to save her own life and that of her unborn child by crawling back inside her apartment, but she died in the doorway.
