NEW YORK (PIX11) – Authorities have arrested and charged two Brooklyn men in connection to the killing of 19-year-old Deandre Matthews, officials said Saturday.

In February, Matthews was reported missing by his mother, a day after filing a missing persons report, her son’s body was discovered when police responded to a 911 call on Nostrand Avenue.

Officers who responded to the call approached an unidentified male laying on train tracks. They discovered he was unconscious and had burn wounds all over his body, police said.

EMS was called in and the unidentified male was pronounced dead at the scene. Upon evaluation by the medical examiner, it was determined the male had sustained a gunshot wound to the head and showed signs of smoke inhalation, police said.

Upon further investigation, the victim was discovered to be Matthews. His death was deemed a homicide by the medical examiner.

It remains unclear what led authorities to 19-year-old Isaiah Baez and 24-year-old Remy McPrecia, of Brooklyn. Both were arrested in connection to the homicide.

Baez is facing charges of murder, criminal possession of a weapon, and tampering with physical evidence in order to conceal and destroy. McPrecia is facing charges for the concealment of a human corpse.
