A Russell man has been charged with a fatal shooting in Warren County on Memorial Day, according to Pennsylvania State Police.

Mark Saullo, 62, was arrested at the scene and later arraigned on a count of homicide. He was denied bond and taken to the Warren County Prison.

Police were called to 2 S. Main St. in Pine Grove Township around 9:25 p.m. Monday for a shooting.

Troopers said Saullo and the victim - Keith Haskins, 55, of Russell - were involved in a brief fight inside a building when Saullo got a gun and fired a shot, hitting Haskins.

Haskins died from his injuries at the scene, according to state police.

Saullo told investigators he and Haskins were involved in a verbal and physical fight Saturday, but both went their separate ways, and everything was fine. Saullo said he also wrote a letter telling Haskins he was no longer going to be allowed on Saullo's property, according to the criminal complaint.

Investigators said Saullo received a phone call Monday about Haskins, who was reportedly mad, coming to the shop where he demanded the title to a vehicle. They started arguing, and Haskins went into the office where the argument escalated into pushing on another, the criminal complaint said.

Saullo said Haskins pushed him on the neck, and Saullo said at one point, he told Haskins he was going to shoot him, according to investigators. Afterwards, he went over to his desk, retrieved a .40 caliber semi-automatic pistol. He fired the gun after Haskins allegedly hit him with the back of his hand, the criminal complaint said.
