Sean Maschal, 33, of Mount Carmel, Pennsylvania, was found shot in the head on September 13, 2017, in a wooded area along Route 54 in Mount Carmel Township. State police reported he had been shot in the back of the head while inside an SUV and his body was later dumped in the woods.

Authorities charged 37-year-old Brian Heffner of Coal Township with homicide and abuse of a corpse; arrest papers allege Heffner shot Maschal and disposed of the body. Maschal’s sister, Taylor Glassic, was arrested on unrelated drug charges, and a search warrant suggested she and three others — David Swatsky, Jamie McCabe, and David Brown — may have conspired to rob Maschal, a plot that investigators tied to his death, though those three have not been charged with murder.

Maschal’s family described him as friendly and outgoing and said he was a devoted father. Who in the community has information about Maschal’s movements or contacts in the days before September 13, 2017?
