Robert Schreffler, 22, of Williamsport, was arrested and arraigned by District Judge Leo Armbruster in Lewisburg on charges of attempted murder, criminal conspiracy and aggravated assault. Police did not say whether Schreffler handled the gun, or whether the gun was loaded or recovered.

Joseph Williams, 19, of Glenside, Montgomery County, was apprehended in June near Philadelphia.

The four are accused of burglarizing Sampsell’s home looking for drugs and money, police reported.

The four men broke into Sampsell’s home by unlocking a screen door through a dog door, a criminal complaint said.

Earlier break-in

Schreffler had burglarized Sampsell’s home a few weeks earlier and had stolen firearms, police said. Two of the guns were used in the May 22 break-in and assault.

Once inside the home, the four men broke down Sampsell’s locked bedroom door and one of them began hitting him in the head and face as many as 11 times with a firearm, police said.

Sampsell freed himself and reached for a gun in his bed.

One of the alleged attackers fired his weapon and then pointed it at Sampsell and pulled the trigger, but it misfired. The men fled the home, leaving the guns at the scene.
