Two NYCT supervisors found dead

Two New York City Transit supervisors were found shot to death in a trailer at a rail yard in Coney Island Thursday.

An anonymous spokesperson for police told CNN that authorities have someone in custody and are questioning him about the murders. The source also said investigators are trying to determine whether the men were shot by a disgruntled co-worker.

A security guard found the bodies of the two men, who were cleaning supervisors, at about 7:40 a.m. They were found in the corner of a trailer used as a break room for workers in the area.

NYCT President Lawrence Reuter says police interviewed about 50 co-workers from the overnight shift. He says transit chaplains and grief counselors are on the scene offering assistance to workers.
