Mississippi police reported they discovered human remains in an abandoned home after witnesses spotted a dog carrying around a severed arm. 

"That is a very graphic and brutal picture. The mutilation of a body, my reaction is one of disgust, is one of concern," said Jackson Mayor Chokwe A. Lumumba at a Monday news conference. "It’s not something you grow accustomed to - it’s never something you want to grow accustomed to."

Deputy Police Chief Deric Hearn said officers found the remains Sunday after someone called Saturday to report the dog carrying what appeared to be an arm. 

Officers found the rest of the body at an abandoned home in the woods and discovered the head also missing, though they later recovered it.

Hearn said the department will continue "actively investigating the matter" and "following up on all leads" at several locations.
