WELLS (AP) – An autopsy Wednesday on the body of a young man found dead outside a boarding house was inconclusive, with Maine State Police saying more investigative work will be needed before a cause of death is established.

The body was found Tuesday outside the boarding house on U.S. 1 that caters to guest workers from outside the United States. The dead man was believed to be 20 years old and from Eastern Europe.

Investigators hope fingerprints can confirm the man’s identity, according to spokesman Stephen McCausland of the state Public Safety Department. He said the process was not expected to be completed Wednesday.

The death was being investigated by state police homicide detectives and Wells police.
