A Schuylkill County judge has sentenced a convicted murderer to 20 to 40 years in jail.

Eric Mumaw was sentenced Thursday on a charge of third-degree murder in the shooting death of David D. Gombert of Beaver Meadows.

Gombert was shot in Mumaw’s Kline Township home on the morning of Nov. 1, 2016.

According to testimony presented during the trial, hostile Facebook posts escalated a romantic rivalry between Mumaw and Gombert. Mumaw’s former girlfriend had become friends with Gombert.

There were four charges related to the murder — first-degree, third-degree, voluntary manslaughter and involuntary manslaughter.

The jury deliberated 12 hours in November and returned a verdict of third-degree murder.

The jury also found Mumaw, 32, guilty of lesser charges, including reckless endangerment, prohibited offensive weapons, possessing an instrument of crime, simple and aggravated assault with a deadly weapon and abuse of a corpse.

He was found not guilty of tampering with physical evidence.
