DENVER — Denver police say a 21-year-old man has been arrested in the shooting death of a policewoman at a city park.
Police Chief Robert White said Monday that Rollen Oliver was arrested on suspicion of first-degree murder in the fatal shooting of 32-year-old Officer Celena Hollis on Sunday.
Hollis was a single mother.
Police say she was trying to break up a fight when she was shot in the head. She was in uniform and working off-duty.
White says investigators don't believe the shots were aimed at Hollis, but they're not sure.
Earlier, police said they arrested one man on a weapons charge but didn't believe he was involved in the officer's shooting. It wasn't immediately clear if that was Oliver or someone else.
