A retired Hudson Valley police officer is accused of killing four men in the local area, including murdering one with a zip tie.

Nicholas Tartaglione is a former cop in Pawling, Mount Vernon, Yonkers and Briarcliff Manor who's accused of killing four Hudson Valley men in 2016.

Martin Santos-Luna, 41, 25-year-old Miguel Sosa-Luna, Urbano Morales-Santiago, 35, and 32-year-old Hector Gutierrez, all of Middletown, were last seen on April 11, 2016, near the Chester Diner.

Their bodies were allegedly found months later on Otisville property owned by Tartaglione, in what police described as a "burial site."

A new court filing details how the former cop allegedly killed the four men.

Tartaglione lured Luna and three other men to an Orange County lounge where the ex-cop and others attacked, officials say.

Tartaglione is accused of hitting Luna repeatedly and killing him by placing a zip tie around Luna's neck, according to the New York Post. The other three men were shot in the head, police say.

Tartaglione is being held at the Metropolitan Correctional Center awaiting trial.
