Nathan Rohrabaugh, 21, of Julian, was sentenced Tuesday to four to eight years in prison after pleading guilty to four charges of delivering heroin.

Rohrabaugh and Derek Schalk, 23, who pleaded guilty to three counts of delivering heroin, were arrested in January and accused of injecting two sisters with heroin. The arrest resulted from a Jan. 5 incident in which a 19-year-old woman was found unresponsive in a parked vehicle in the HUB-Robeson Center's parking deck, according to court documents.

Schalk's sentencing date has not been scheduled.
