Subway Cameras Led to Arrests in D Train Killing, Police Say

Police on Monday said footage from a surveillance camera in a subway car helped lead to the arrests of three people in connection with the fatal shooting of a 45-year-old man last week.

Justin Herde, 24, Alfredo Trinidad, 42, and Betty Cotto, 38, were in custody in connection with the killing of William Alvarez, 45, of the Bronx, according to the New York Police Department.

Mr. Alvarez was riding a southbound D train around 5 a.m. on Friday morning when the three suspects boarded at the Fordham Road station and got into an argument with him, the police said. Mr. Alvarez was shot in the chest, Michael M. Kemper, the Police Department’s chief of transit, said at a Monday news conference. Chief Kemper added that Mr. Alvarez’s attackers fled the train at the 182nd-183rd Streets station.

About 1,000 of the system’s roughly 6,500 cars are equipped with cameras, part of a broader effort begun in 2022 by the Metropolitan Transportation Authority, which plans to install cameras in the rest of the cars by the end of this year.

Killings on the subway are rare, but attract intense public attention. This year there have been two other fatal incidents in the system. Earlier this month, a 35-year-old man was killed and five other people were wounded in a shooting at the Mount Eden Avenue station in the Bronx during the evening rush hour. And in January, a 45-year-old father of three was shot on a No. 3 train in Brooklyn after intervening in an argument.

Transit leaders are under intense pressure to bring ridership back to prepandemic levels, and making the system feel safe is critical to that mission. Ridership rose by about 3 percent in January, hovering on average at about 3 million daily passengers. In 2019, daily ridership was about 5 million.
