MINNEAPOLIS — Homicide investigators are talking to neighbors and processing evidence after a dead man was found on a railroad bridge in northeast Minneapolis Tuesday morning.

Police spokesperson Darcy Horn says just after 6:30 a.m. a passerby spotted what appeared to be a person down on the bridge, which is near the intersection of 16th Avenue Northeast and Marshall Street, and then called 911. First responders found the victim, who was declared dead on the scene.  

Investigators aren't commenting on the nature of the man's injuries or potential cause of death. 

Crime lab technicians are on the scene processing evidence while homicide detectives are canvassing the neighborhood and talking to anyone who may have seen or heard something. At this point no suspects have been identified.

It's the second Minneapolis homicide investigation in 24 hours, with a body being found on a bike trail just before midnight Monday. Police are also trying to find the person or persons who shot up a home on the city's north side Monday morning, hitting a 5-year-old girl, taxing investigative resources.
