A Hudson Valley school security guard is accused of killing four local men.

On Thursday, FBI agents announced the arrest of 55-year-old Joseph Biggs of Nanuet in connection to a quadruple murder in Chester.

Biggs, a security guard at a school in Hastings-On-Hudson, was charged on a 17-count indictment, including four-counts of murder, four-counts of kidnaping and conspiracy to distribute and possess five kilograms or more of cocaine.

“Murders are always frightening, but when allegedly committed by people entrusted with the safety of others, it is all the more disturbing,” Acting U.S. Attorney Joon H. Kim said.

As alleged in the indictment filed in White Plains federal court, in April 2016, Nicholas Tartaglione, a retired Briarcliff Manor cop, and Biggs killed Martin Luna, Urbano Santiago, Miguel Luna, and Hector Gutierrez as part of their cocaine distribution conspiracy.

On April 11, 2016, Tartaglione And Biggs lured Martin Luna to a bar called the Likquid Lounge in Chester, where he was held captive and killed. The other three victims accompanied Martin Luna to the bar, where they were then held captive, shot, and killed, officials say.

Tartaglione was charged in a five-count indictment for allegedly killing the four men and conspiring to sell five kilograms or more of cocaine.

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.

In Dec. 2016, their four dead bodies were found on Otisville property owned by Tartaglione, officials say.

An investigation led authorities to believe that there could be human remains at Tartaglione’s Otisville property. A search warrant led to the discovery of the bodies.

“We are fortunate and humbled to be able to work with such talented people as a team in the arrest of Mr. Biggs in connection with the unspeakable and callous murder of these victims,”

In March, a former Hudson Valley cop, a man who had ties to the Tartaglione, committed suicide after he was pulled over by police near an elementary school.
