The body of a young child was found decomposing inside a duffel bag in a Philadelphia alleyway on Monday, and police say it might be a local boy who was reported missing last year.

In an email to HuffPost on Tuesday, a Philadelphia police spokesperson said a sanitation worker found the duffel bag on Monday morning. Investigators described the remains as in a state of decomposition.

The body is believed to be a child between the age of 4 and 7, but investigators were unable to determine the sex, according to CBS Philadelphia . Police told HuffPost the body was taken to the medical examiners office to determine the childs identity, as well as the cause and manner of death.

Police told CBS Philadelphia that they are trying to determine whether the remains belonged to 4-year-old Damari Carter, who was reported missing in December by family members.
