The man whom police say was involved in a fatal fight with a LaGuardia Community College student at the Bedford Avenue L train station on Friday night won't face murder charges.

A former friend said Beauchamp showed signs of mental illness as a teenager: "He was just kind of an odd bird...He’s kind of gotten crazy over the years and I just kind of ignored him.”

A tipster contacted the police after seeing the sketch; a witness to the altercation also identified him in a photo array.
