The death of a Florida man found in an alley early Thursday in the Loop has been ruled a suicide.

The man, identified as 20-year-old Jet Puentes of Auburndale, Florida, was found unresponsive about 2:30 a.m. in an alley in the first block of West Adams, according to Chicago Police and the Cook County medical examiner’s office.

He was pronounced dead at the scene, authorities said.

An autopsy Friday found he died of multiple injuries from a fall from height, the medical examiner’s office said. His death was ruled a suicide.
