BLOOMINGTON, Minn. (AP) —A group of several hundred protesters gathered Wednesday outside the office of a suburban Minneapolis dentist who killed a protected lion in Zimbabwe.

The demonstrators carried signs Wednesday and chanted outside the Bloomington office of Walter Palmer.

Palmer has said he believed the hunt was legal and didn't know about the lion's status. Some of Palmer's patients are among the protesters.

Signs read "Killer" and "I am Cecil" — the name of the slain lion. Members of the crowd chanted, "Justice for Cecil."

Signs also were taped on Palmer's office door, including "ROT IN HELL" and "PALMER There's a deep cavity waiting for you!"
