A man died after being struck by two vehicles on Roosevelt Boulevard Monday night.
An unidentified man in his mid-30s wearing only in his underwear was running in the southbound outer lanes of the Boulevard at Harbison Avenue just after 8 p.m. waving his arms in the air and singing loudly, said Philadelphia Police.
"He was running south on the Boulevard waving his hands in the air and he was singing loudly," said Philadelphia Police Chief Inspector Scott Small.

A silver Chevy Tahoe struck the man and the impact catapulted the man into the air. He then landed in the inner lanes of the Boulevard where another vehicle, a silver Volkswagen, and possibly two other vehicles struck him.
Officers found the man unresponsive on the highway with injuries to his head, body and legs, said Small. Medics rushed the man to Frankford-Torresdale Hospital where he died overnight. Two striking vehicles remained at the scene, said police.
"He was only wearing underwear, which is very bizarre for the winter -- or anytime," said Small.
Investigators said the man had mental health issues and was possibly under the influence of drugs or alcohol.
Police closed the southbound lanes on the Boulevard at the scene of the crash as they investigated. Investigators checked surveillance video to see if two other vehicles that didn't remain on the scene also struck the man.
