Cody Smith was sentenced Thursday morning of two to four years in prison.
He pleaded guilty in March to the sex charges.
In addition to the jail time, Smith will serve five years on probation and register as a sex offender.
Smith was a part-time cop for Wyoming borough.
Authorities in Luzerne County accused Smith of having sex with four teenaged girls.
Assistant District Attorney Jennifer Roberts told Newswatch 16 that Smith will not be able to work in law enforcement again.
“One of the reasons that we had agreed upon a sentence in this case was to save the four teenage victims from having to actually go into court and testify,” said Roberts. “He was an individual that a victim would normally go to for help, but he in this case was the defendant. It was just unfortunate and hopefully the community is aware that it was an isolated case.”
