A Mobile police officer was shot late Tuesday and rushed to the University of South Alabama Medical Center, where he died. SWAT teams arrived around 12:30 a.m. Wednesday after a man barricaded himself in a home, authorities said.

At roughly 2:45 a.m, police said the barricade situation “has been resolved.” Minutes later, the suspect, Robert Hollie, was pronounced dead.

The slain officer was identified as Justin Billa.

Mobile Police Chief Lawrence Battiste said officers investigating the Tuesday night death of Fonda Poellnitz had identified her ex-husband, Robert Hollie, as a person of interest. He said Hollie opened fire on officers who had set a perimeter around his Toulminville residence, striking Billa. Battiste says at least one officer fired shots at the scene, but it’s unknown if they struck Hollie.
