LAS VEGAS " Police say they're looking for a 19-year-old man in two armed sex attacks on women in the parking lot of a Las Vegas hospital.
Police Capt. Vincent Cannito calls Roy Trost a -- quote -- "person of interest" in the attacks outside Desert Springs Hospital Medical Center on Flamingo Road near Eastern Avenue.
One attack was reported about midnight Sunday, and witnesses later told police they saw a man hanging around before it occurred.
Police have said Trost should be considered armed and dangerous.
But Trost's roommate tells KLAS-TV he doesn't think Trost has a weapon.
Marco Briody says he found cell phones belonging to the alleged victims in his trash on Monday and turned them over to police.
