Police have identified the man they say fatally gunned down a mentally disturbed individual on a Bronx subway platform on Tuesday during a wild brawl, before begging his family for help while covered in blood. According to NYPD Chief of Detectives Joseph Kenny, 27-year-old Alberto Frias got into an altercation with 41-year-old Adrian Dawodu inside of the 170 Street Station just before 3 p.m. on Feb. 10. Dawodu himself is known to frequent the station and is often seen by MTA staff yelling to himself and others. He was last seen taking the taxi to Harlem, where he is now being hunted by the warrant squad. Frias has previously been arrested for domestic violence and a loaded firearm.
