The Mount Vernon man charged with gunning down his niece over a property dispute once did prison time for the drive-by murder of former NFL star Ray Rice’s father.

Michael Foster, 58, allegedly shot and killed his niece, 39-year-old Julia Anderson, outside her Bronx job on Monday over a bitter squabble over a family home in Westchester County, law enforcement sources have said.

It wasn’t Foster’s first brush with the law.

“What’s of note, your honor, is that the defendant has previously been convicted of manslaughter where he’s served a significant amount of time,” Bronx Assistant District Attorney Burim Namani said in court Thursday as Foster was arraigned.

“This is the second person he’s killed, your honor,” Namani said.

State corrections records show that he was one of four people charged in the 1988 drive-by shooting death of Calvin Reed, the father of the former Baltimore Ravens running back.

Rice, 39, a native of New Rochelle, played for the 2013 Super Bowl champion Ravens, but is best remembered for the caught-on-video slugging his then-girlfriend in an Atlantic City casino elevator the following year – derailing his football career. He later married the woman, Janay Palmer, but the shocking footage never faded.

Rice was still in diapers when Reed was killed — with Foster later hit with a sentence of 4 to 20 years in state prison on a first-degree manslaughter conviction.

Foster was denied parole three times before he was released in 1999, state records show.

He and his niece were embroiled into a legal dispute over a home at 18 Bell Avenue in Mount Vernon –when he allegedly shot her several times in the stomach as she was about to step into her Jeep in Wakefield.

Records show that Foster and Anderson shared ownership of the home, but in recent years got into a bitter fight over who was the rightful owner.

In October, Anderson even filed a $27 million federal lawsuit against Westchester County prosecutors over her April 2025 arrest on accusations of “theft involving family property documents.”

The court document suggests she blamed her uncle for the arrest.

“What began as a civil family dispute was transformed—without investigation or legal basis — into a months-long criminal ordeal that left deep and lasting scars,” the federal filing said.

“The entire process was initiated not through evidence or probable cause, but through the unvetted statements of a known felon with a violent criminal history and a personal vendetta,” it said, in an apparent reference to Foster.

He was ordered held without bail on murder, manslaughter and weapons charges for his niece’s fatal shooting.

Outside the home, a relative told The Post on Thursday that she was “heartbroken” by the senseless slaying.

“I’m falling apart,” said the 74-year-old woman, who declined to give her name. She said Anderson was married, but had no children.

“I came home from work, I saw a lot of police cars,” she recalled. “I couldn’t open my door. I didn’t know what was going on. I heard people talking.

“‘What happened?’” she said she finally asked. “It’s Julie.”
