The man accused of shooting a cop to death in East Harlem Tuesday night is known as a “half loner-half lunatic” who began his life of crime at the tender age of 13 — and was being sought in connection with another shooting when he killed Officer Randolph Holder, police sources said.
Suspect Tyrone Howard, 30, was wanted for questioning about an eight-week old shooting in the same neighborhood when he swapped shots with Holder and his partner on a pedestrian overpass above the FDR Drive near 120th St. around 8:30 p.m., officials said.
