MINNEAPOLIS — The dental practice of a Minnesota man who killed a well-known lion in Zimbabwe has reopened.

Walter Palmer’s River Bluff Dental said in a tweet Monday that it was beginning to see patients again. The tweet said Palmer wasn’t at the office.

Palmer’s office in suburban Minneapolis had been closed since late July after a barrage of criticism of Palmer over the killing of a protected lion named Cecil. Palmer says he relied on his hunting guides to ensure a legal hunt in Zimbabwe.

An Associated Press reporter saw people going in and out of River Bluff Dental. A security guard posted outside the building Monday declined to answer questions and told the reporter he had to leave.

Palmer has not returned repeated calls for comment.
