A bag of bones hidden in shrubs in the backyard of a vacant home in the city's Longmead-Puritas neighborhood belong to a young boy who has not been reported missing, officials said on Wednesday.

Cuyahoga County Medical Examiner Thomas Gilson and Cleveland Police Chief Calvin Williams are asking the public's help in identifying the child, who is believed to be about 4 years old.

Gilson said they have not yet determined how the child died, but called the death "extremely suspicious." Gilson said it appeared the boy had been dead for several months and likely died sometime in the late spring or early summer. 

The boy is described as having long wavy dark hair and brown eyes, Gilson said. Investigators have been unable to determine the child's race. Analyzing skeletal remains of children is more difficult to analyze than adult remains, Gilson said.

He appears to be at the average heights and weight of a 4-year-old and had no prior health issues, Gilson said.
