Baltimore detective shot in head, 'cold, callous' gunman sought
Baltimore police said in a tweet that one of their officers was shot Wednesday evening.
"He may be wounded", Davis says.
Police only had a vague description of the suspect, saying he is a black man who wore a black jacket with a white stripe.
Minutes later the man shot the detective in the head and took off. Suiter was shot in a vacant spot in between two homes, where another house once stood.
She said Baltimore can and will "do better", if all city residents pitch in. We grieve for his loss, and for the pain and suffering that will be endured by his family and friends. He will never be forgotten, and his sacrifice will be remembered forever by the generations of proud Baltimore police officers yet to come. He was dressed from head to toe, like every other homicide detective in Baltimore is dressed: full suit, tie, badge displayed on his waistband. "We will take it from here". According to the latest report, that reward is now at $69,000.More news: Manhattan fire: Firefighters battle blaze in six-storey Harlem apartment building
