SUNBURY - A Sunbury man who exited Northumberland County Courthouse Monday afternoon prior to being sentenced on assault charges turned himself into the U.S. Marshals Service Thursday morning.

Brian Badman, 29, was committed to the county prison, where he will await sentencing.

Badman reportedly turned himself in at about 9 a.m. at an undisclosed location in Sunbury and was escorted to the prison by U.S. marshals.

A bench warrant was issued Monday for Badman for failing to appear for sentencing and violating conditions of his bail supervision.

Badman was scheduled to be sentenced by Judge Charles Saylor at 1:30 p.m., but when his case was called, he couldn't be located, prompting Saylor to issue the warrant.

Sunbury police and county deputy sheriffs joined adult probation officers in conducting a search for the defendant at a residence on Pennsylvania Avenue and other homes where he formerly resided, but were unable to locate him.

Badman pleaded guilty May 8 to a felony of aggravated assault and misdemeanor of simple assault.

Multiple other charges were not scheduled to be prosecuted at Monday's sentencing.

Badman and his brother, Damian Badman, 31, of Shamokin, were charged by city police with four counts each of aggravated assault and criminal conspiracy to commit aggravated assault, a misdemeanor of possessing an instrument of crime and two misdemeanor counts of simple assault in connection with the Oct. 11 stabbing of Shawn Snurkowski, 26, of North Sixth Street, Sunbury.

Police said Snurkowski was in the 100 block of North Sixth Street with his children when the Badmans and a female arrived and an argument began.

During the argument, police said Damian Badman threw a can of beer at Snurkowski and his children. When the argument escalated, the Badmans allegedly stabbed Snurkowski in the chest, neck and back, in front of witnesses. One witness, Amber Edwards, was cut on her left arm while trying to break up the fight.

Snurkowski and Edwards required treatment at Geisinger Medical Center, Danville.

After the stabbing, the Badmans and the unidentified female fled the scene in a silver Volkswagen Jetta with tinted windows. They were taken into the custody near the Cameron Bridge in Shamokin by Shamokin and Coal Township police.
