After pregnant mother Brittney Mills, 29, was shot and killed last week, doctors rushed to deliver her baby, but the child, Brenton Mills, died Friday, Baton Rouge police reported.

Brittney Mills was shot several times at her Ship Drive apartment on April 24, likely by someone she knew. Cpl. Don Coppola has said investigators believe the shooting was prompted when she refused to lend her car to her attacker.

Former LSU offensive lineman La’el Collins, who is scheduled to meet with Baton Rouge police on Monday but who has not been named a suspect, plans to take a paternity test to determine if he was the father of the child, a source confirmed to The Advocate.

Police have said Collins was “one of many” people officers want to talk to as they investigate the deaths of Mills and her infant son.

Collins’ attorney, Jim Boren, has declined to comment on the relationship between Collins and Brittney Mills.

Collins did not get selected in Thursday’s or Friday’s rounds of the NFL draft. He had returned to Baton Rouge from Chicago on Wednesday with plans to meet with detectives.

Police said Thursday that detectives originally reached out to Collins’ family and his agent Saturday in an effort to speak with him. It wasn’t until Thursday that Collins, through a representative, agreed to speak with them after the draft, police said, and detectives have yet to hear from Collins himself.

Cpl. L’Jean McKneely, a Baton Rouge police spokesman, on Friday declined comment on the DNA test. McKneely also declined comment on the date of Collins’ meeting, which, a source said, will happen Monday.

Police had no new information to offer Friday about the investigation into the deaths. They still have no suspects in the case.

Brittney Mills, who also has a 10-year-old daughter, was about nine months’ pregnant and had recently had a baby shower, neighbors said soon after the shooting. Several reported hearing two shots about 10:30 p.m. the night of the shooting, and that the door to the apartment was ajar when officers arrived.

Attempts to contact the Mills family Friday evening were unsuccessful.

Police say the shooting is still under investigation and are urging anyone with information to come forward and call the Violent Crimes Unit at (225) 389-4869.
