A teenager was shot and left for dead Wednesday in the middle of a Brooklyn street — where his body blocked a passing snowplow that became caught in the middle of the crime scene.

Trevon Dickens, 19, was found shot once in the head outside 752 E. 91st St. near Avenue B in East Flatbush around 6:15 p.m., police said.

A snowplow with the city’s Sanitation Department was in the middle of clearing the street when it came across the body, cops said.

Police cordoned off the crime scene — with the plow in the middle — with blue tape as they investigated. Dickens’ body was draped in a white sheet.

Dickens, of East New York, was pronounced dead at the scene.

Police haven’t made any arrests or identified a motive.
