SUNBURY - Brian Badman, 29, of Sunbury, who walked out of Northumberland County Courthouse Monday afternoon before being sentenced on assault charges and later turned himself into authorities, had his plea agreement with the district attorney's office rejected Friday by Northumberland County Judge Charles Saylor.

The judge also increased Badman's bail from $125,000 unsecured to $250,000 cash and he remains in Northumberland County Prison.

Assistant District Attorney Michael Seward said Badman's plea agreement called for him to serve 3 to 6 years in state prison on a felony of aggravated assault and misdemeanor of simple assault, to which he pleaded guilty May 8.

Badman, who is represented by county chief public defender Edward Greco, was ordered by Saylor to appear for a pre-trial conference June 6.

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

Badman was able to elude authorities after exiting the courthouse, but turned himself into the U.S. Marshals Service Thursday morning at an undisclosed location in Sunbury and was escorted to the county prison.

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.
