A former New York police officer and cellmate of disgraced financier Jeffrey Epstein was found guilty Thursday of killing four men in 2015, the US Attorney for the Southern District of New York announced. Nicholas Tartaglione, who is described by US Attorney Damien Williams as “a former police officer-turned drug dealer,” faces a possible life sentence in federal prison after a jury found him guilty of killing Martin Luna, Miguel Luna, Urbano Santiago and Hector Gutierrez, according to a Thursday news release. Tartaglione shared a prison cell with Epstein at the federal Metropolitan Correctional Center in New York City and had been moved before Epstein’s suicide in August 2019, CNN previously reported
