(CNN) -- A suspect in the shooting of five people in a rural Pennsylvania home was killed Monday morning after a six-hour standoff with police, according to a district attorney's office.
Suspect Mark Richard Geisenheyer entered a standoff with a Delaware County SWAT unit Monday morning armed and unwilling to surrender, according to a release by Montgomery County's First Assistant District Attorney Kevin R. Steele. The killings took place in Montgomery County, 50 miles north of where the suspect was found.
Geisenheyer was in a home basement in Trainer, Pennsylvania, in Delaware County.
Following the SWAT team's entry, Geisenheyer was shot and pronounced dead at the scene by the Delaware County medical examiner, according to Steele.
The suspect's death comes in connection with a home shooting Saturday that left two dead and three fighting for their lives. Police responded to a call from a rural farmhouse in the town of Bechtelsville, Montgomery County.
Homeowners Paul Shay, 64, and Monica Shay, 58, were found in critical condition. The two victims pronounced dead at the scene were Joseph Shay, 43, of West Yarmouth, Massachusetts, and Gregory Bosco, 2, the child of Kathryn Erdmann, 37. Erdmann was hospitalized in critical condition, according to Steele.
None of the surviving victims were able to speak to investigators at first, but Erdmann and Paul Shay have since begun speaking and are expected to survive, according to Steele.
