Lehigh County authorities are investigating the deaths of two people found inside a building in the 900 block of West Washington Street Sunday afternoon.

But police say the deaths do not appear to be suspicious.

The Lehigh County Coroner's Office pronounced 20-year-old Alexandra Cramsey dead at 3 p.m. Sunday at 938 W. Washington St. An autopsy is scheduled for Monday to determine the Cramsey's cause and manner of death.

Cramsey lived in the 5300 block of Hamilton Boulevard in Lower Macungie Township.

The coroner's office also pronounced Marquilis Calhoun dead. An autopsy on the 22-year-old is scheduled for Tuesday.

Authorities list Calhoun's address as 938 W. Washington St., but Lehigh County property records list the building as a storage warehouse. It was not immediately clear whether Calhoun lived in the building.

Allentown police said the deaths remain under investigation and that authorities are awaiting the results of toxicology tests.
