Police have identified the suspect wanted in connection with a verbal and physical altercation on a subway platform that left a college student from Queens dead over the weekend.

 

Ryan Beauchamp, 33, is being sought by police in the fight that led to 20-year-old Joshua Basin's death.

 

Police identified Beauchamp as a suspect through a previous arrest in connection with an Occupy Wall Street protest on Oct. 8, 2011, according to police sources.

 

Beauchamp, who is homeless, also has a previous arrest in Connecticut, the sources told NBC New York.

The argument between Beauchamp and Basin, of Howard Beach, began as a verbal dispute while the two men were riding the Manhattan-bound L train Friday.

Both men exited the train at the Bedford Avenue station, where police and witnesses say the fight turned physical.

They fell into the train tracks. Beauchamp was able to get back to the platform, but Basin could not get off the tracks. He was struck by an oncoming L train.

He was transported to Bellevue Hospital and was later pronounced dead. 

Basin was a student at LaGuardia Community College in Long Island City studying psychology.

Anyone with information on Beauchamp or about the incident is asked to call Crime Stoppers at 1-800-577-TIPS. Tips can also be submitted online here.
