Five people have been charged with selling heroin to authorities in a series of undercover buys in Centre County.
State police said Robert Carlin and Amanda Grieb, both of Philipsburg; Holly Simcisko, of Moshannon; Erika Miller, of Milesburg; and Christopher Long, of Clarence, face felony charges.
Police said the five were charged for their roles in selling heroin in Patton and College townships and Pleasant Gap, Snow Shoe and Milesburg.
Carlin, Grieb and Simcisko were placed in the Centre County Correctional Facility after failing to post bail, according to court documents.
Police have yet to take Miller and Long into custody, those documents show.
According to two separate criminal complaints, Carlin, 26, and Grieb, 21, sold eight bags of heroin for $200 on two occasions in May at Sheetz convenience store parking lots in College and Patton township and once outside a restaurant in Spring Township.
Simcisko, 20, and Miller, 20, were charged for their alleged roles in selling eight bags of heroin in August near the Milesburg fire hall.
Simcisko also allegedly sold undercover authorities four bags of heroin in August at a home in Snow Shoe and another three bags there in September.
Police said the five were arrested as part of an investigation into the transportation of heroin into the county and its resale here.
Troopers from Philipsburg, Rockview and Hollidaysburg barracks and the state police Bureau of Criminal Investigation assisted in the investigation.
