Jaishawn Gaston, of Jersey City, has been charged with first-degree murder and two counts of unlawful weapons possession, Hudson County Prosecutor Esther Suarez said Wednesday.

Francis Villa was found dead of a gunshot wound to the head on the evening of August 31 in a Forrest Street apartment in Jersey City, according to Suarez.

Gaston was arrested Tuesday about 7:30 p.m. when he turned himself in at the prosecutor’s office in Jersey City accompanied by his attorney.

The manner of death was ruled homicide on Monday by the Regional Medical Examiner’s Office.
