UPDATED: Gunman Dead From Self-Inflicted Shot; Had Prior Standoff

Sunday 5:14 p.m. 

Correction: Name of gunman was reported incorrectly by media sources. Correct name is Mark McCarty.

Sunday, 3:21 p.m.:

Citing Bucks County Coroner Joseph Campbell, 6abc.com reports the suspect has been identified as 58-year-old Levittown resident Mark McCarpy.

According to police, McCarpy was found in puddle of his own blood on the floor of the Dick’s Sporting Goods store bathroom at around 11:30 p.m. He died on a single gunshot wound to the chest.

A quick search of online court records in Bucks, Montgomery and Philadelphia does not produce any recent arrests for McCarpy.

Official sources confirm that the suspect had a past spotted with mental health issues. Falls Township police Lt. Hank Ward said McCarpy was involved in a standoff with Middletown police in 2002 and was involuntarily committed for care in 2010.

Sunday, 1:25 a.m.:

A man in his mid-50s was found dead inside the bathroom at the Dick’s Sporting Goods store on Commerce Boulevard in Falls Township late Saturday night, police said.

The incident all started when the man entered the gun section of the store at 7 p.m. and asked to see a 12-gauge shotgun. The suspect then pulled a handgun on the clerk and asked him to remove the gun lock from the shotgun and to call the police, spokesperson Lt. Hank Ward said. Around that moment, the man grabbed ammunition and loaded the gun.

As store employees worked to clear the building, police said they systematically began clearing the store and “confronted” the man. Ward told reporters next ran into the bathroom and was not heard from in over three hours.

Members of the South Central Emergency Response Team tried to make contact with the man for more than three hours before he was found in a bathroom in a pool of his blood, his gun nearby, police said.

Using a special robot, police found the man dead and entered the bathroom with a K-9 unit and tactical operators, Ward said.

The Middletown man engaged in a standoff with police in that township in 2002 and had to be involuntarily committed for mental health issues in 2010, police said. Few further details about his life were available as of early morning.

“Family members were in recent contact with him and he seemed fine,” Ward said.

A green Ford Ranger pick-up truck believed to belong to the suspect was searched outside the store by police.

During the standoff, police cut some of the electric service to the store, Ward said to LevittownNow.com.

Surrounding stores in the shopping center were evacuated a few minutes after 7 p.m. and a large crowd of bystanders gathered in the parking lot.

Police from around the lower portion of Bucks County rushed to the scene. By 9 p.m., a Lenco Bearcat armored truck was brought to the scene as a precaution.

Firefighters and ambulance crews were turned away from the scene shortly after the body was discovered before midnight.
