Charles Moose, a former Maryland police chief who led the D.C. sniper investigation in 2002, has died. He was 68.

"We are extremely saddened by the news announcing the passing of former Chief Charles Moose," said current Montgomery Chief Marcus Jones. "He was a great leader and led our department through the D.C. sniper investigation, one of the most difficult crime sprees in our country’s history. We send condolences to his wife Sandy and all of his family and friends."
