The roommate of Sebastian Zapeta, the Guatemalan migrant who police say horrifically killed a woman by setting her on fire as she slept on an F train in Brooklyn, and then watched as she burned to death, said Tuesday that Zapeta seemed like a "regular guy" who gave no indication that he could turn violent.

Raymont Robinson, 54, who slept across from Zapeta for three nights at Forbell Men's Shelter in Brooklyn, and hung out with him several times, told the Daily News that Zapeta was "like an average guy," who drank alcohol and smoked the synthetic drug K2 to the point where he would frequently space out in conversation, but did not otherwise act in a way that concerned him.
