Lawrence E. Purcell Jr., 34, was shot and killed on February 14, 2017, at a home on Glenwood Road in Chestnuthill Township near Effort, Pennsylvania. Police say the shooting occurred during a violent altercation at the residence of Kyle Brant Kresge, 46; Purcell was shot in the chest and died at the scene. Kresge then dragged the body outside and covered it with debris.

Investigators reported that several people at the scene, including Kresge and Purcell, were under the influence of methamphetamine, heroin, and/or cocaine. Witnesses said Kresge fired a warning shot into the ceiling before shooting Purcell. Kresge was arrested and charged with criminal homicide, abuse of a corpse, and tampering with physical evidence; after a non-jury trial he was convicted of third-degree murder. The judge found malice but not premeditation and sentenced Kresge to 20 to 40 years in state prison, with additional time for the other convictions.
