Though the investigation has not yet been concluded, Rahmael Sal Holt has been arrested and charged with first-degree murder of a law enforcement officer, murder in the first degree, possession of a firearm and carrying a firearm without a license. Holt had been on the run after shooting and killing New Kensington police officer Brian Shaw, and the manhunt was concluded when authorities subdued him 3.5 days later.

SWAT arrested him in Pittsburgh at a home, along with family and friends who were housing him, including his mother Sherry Holt, according to Pittsburgh’s Tribune Review.  He is being held without bail.

Officer Shaw, 25, had not yet served a year with the New Kensington Police Department when he stopped Holt during a regular traffic stop at 8 p.m. on a Friday. Holt attempted to escape on foot, and Officer Shaw pursued him into a parking lot. Drawing a pistol, Holt fired upon Officer Shaw six times with a .40 caliber weapon, fatally wounding him. Shaw would die at a nearby hospital.

As it was stated before, the investigation has not yet been concluded—among other things, the murder weapon is still missing. However, the casings were found at the scene of the crime and the arrest of Rahmael Sal Holt may prove to bring more evidence to light.
