“The body discovered appears to be that of a young female, although we have not positively identified the body, we believe that she is Madyson Middleton,” said the chief at a press conference.

Officers arrested a 15-year-old suspect on suspicion of homicide. Detectives were questioning the teen, according to police.

The teen lives at the Tannery Arts Center and was there at the same time as the body was discovered, police said.

“He was one of the sweetest kids we have at the Tannery,” said another man. “We know he didn’t do this.”

Other neighbors told KCBS they were devastated when they got word the community search effort had reached this tragic conclusion.

“This has really hit me really hard. I got 4 grandkids, it’s tough… when they started taping the area off — that’s not a good feeling,” said another woman.

The suspect’s relationship to the victim is not currently known, nor the cause of death, according to police.
