Annie Sandifer

MILWAUKEE (AP) — Authorities on Monday searched for suspects in the killing of a pregnant woman who was shot on the weekend while aboard a party bus parked outside a Milwaukee restaurant and bar.

Milwaukee police said Monday that the investigation into the death of Annie Sandifer is active and ongoing and that police were still seeking suspects and trying to determine a motive.

The shooting happened at about 2:30 a.m. Saturday. A gunman in a passing car fired five or six shots outside Gene’s Supper Club, hitting Sandifer, a mother of five. The bus rushed her to a hospital, but she didn’t survive. Doctors were able to deliver Sandifer’s baby via an emergency cesarean section, police said. The baby was in stable condition Monday, but delivered just 26 weeks into the pregnancy, it was born very premature.

Police said Sunday it wasn’t clear whether the bus was the intended target of the attack.

At a Saturday evening vigil, family described Sandifer as a loving, giving mother to her children, the Milwaukee Journal Sentinel reported.

“She did everything, like a mother should,” said her cousin, Kisha Ducksworth. “She went out of her way for her kids.”
