SUNBURY - A 21-year-old Shamokin woman charged in connection with the assault of a probation officer and an escape, drug offenses and driving under the influence of alcohol was sentenced Monday morning to 6 to 24 months in SCI-Muncy.

Northumberland County President Judge Robert B. Sacavage imposed the sentence on Stormie Birster, who was ordered to immediately begin her jail term.

Birster, who had been free on bail, previously pleaded guilty to aggravated assault, possession of drug paraphernalia and DUI relating to three different incidents in Shamokin.

The defendant, represented by Attorney Michael Rudinski of Williamsport, also was directed to pay $600 in fines and various costs and fees, complete a stress and anger management course and refrain from drinking alcohol.

She was given credit for five months previously served in Northumberland County.

Birster received the prison sentence on a felony of aggravated assault involving an Oct. 6, 2011, disturbance at her former residence at 11 N. Market St., Apt. 3, Shamokin.

Birster, who allegedly fled from police while being evaluated at then-Shamokin Area Community Hospital following the disturbance, later turned herself into authorities.

An additional felony offense of escape, and misdemeanors of resisting arrest, disorderly conduct and simple assault were not prosecuted under a plea agreement.

Birster's 19-year-old sister, Marissa Birster, of Shamokin, and Steven L. Rivera, 22, of Shamokin, who was Stormie Birster's live-in boyfriend at the time of the disturbance, also were charged in the incident on Oct. 6, 2001.

Marissa Birster remains free on bail. Rivera is incarcerated at the county jail.

Their court cases involving the Oct. 6, 2011, disturbance are still pending.

All the charges were filed by Shamokin Patrolman Nathan Rhodes.


According to a criminal complaint, police were dispatched to assist Northumberland County adult probation officers John Rosinski, Matthew Narcavage, Dan Shoop and Jason Lasko with a fight at 11:50 p.m. that broke out during a visit to Rivera's apartment.

According to Rosinski, while the probation officers were walking through the residence, Stormie Birster began harassing them.

Rosinski told Birster that if she didn't leave, Rivera was going to jail.

Rosinski said Birster then calmed down and agreed to leave the apartment before they encountered Marissa Birster at the entryway.

Shoop handcuffed Rivera, who was led downstairs by Shoop and Lasko. Rosinski said the Birster sisters followed Rivera and the probation officers down the steps and within seconds, chaos ensued in the stairwell, according to Rosinski.

Rosinski said he observed Stormie Birster, who was on her backside, punch Shoop in the face, while Marissa Birster was lying on top of Shoop as he was getting punched.

Police and probation officers then took all three defendants into custody.

Police said the Birster sisters then requested to be evaluated by emergency medical services personnel, who treated the siblings and transported them for follow up evaluations in the emergency room at then-Shamokin Area Community Hospital. The Birsters were met at the hospital by Shamokin Patrolman Scott Weaver and Special Officer 2 Norman Lukoskie because they were still in police custody.

While in the emergency room, Stormie Birster was placed into an exam room and told to wait for a doctor. Police said Birster opened the exam room door and ran out of the hospital into the Tharptown area.

She was later convinced by police to turn herself over to authorities.

Other incidents

Stormie Birster was sentenced to 12 months probation for possession of drug paraphernalia relating to a July 24, 2011, incident at Independence and Market streets in Shamokin. An additional charge of underage drinking filed by Shamokin Patrolman Raymond Siko II was not prosecuted.

The defendant also was sentenced to 72 hours to 6 months in state prison for driving under the influence of alcohol involving a May 29, 2012, incident at Independence and Rock streets in Shamokin. Two additional counts of DUI and charges of underage drinking, driving without a license and careless driving filed by Siko were not prosecuted.

The sentences imposed for DUI and possession of drug paraphernalia run concurrent to the sentence Birster received for aggravated assault.

Northumberland County District Attorney Toby Rosini represented the commonwealth at Birster's sentence.
