When people think about America’s most notorious serial killers, the same names usually come up: Ted Bundy, Jeffrey Dahmer, Gary Ridgway and John Wayne Gacy.
Pittsburgh usually isn’t part of that conversation.
But buried in Western Pennsylvania’s crime history is the disturbing story of Gary A. Robbins, a Murrysville man with ties to Squirrel Hill who authorities eventually suspected of being responsible for murders and brutal attacks against women across several states.
Robbins died before investigators could ever put him on trial or determine the full extent of what he may have done.
And the event that finally exposed him began at the front door of a woman in Somerset County.
The Woman Who Survived
On April 14, 1988, Robbins showed up at the Brothersvalley home of Mary Ann Marker, whose husband, David Marker, was a Pennsylvania state trooper.
Robbins asked her for directions to the Maple Festival. Then he shot her in the face with a .22-caliber weapon.
Marker survived.
Despite being critically wounded, she locked the door after Robbins fled and managed to call the Pennsylvania State Police. Even after being shot, she provided police with an extraordinarily detailed description of her attacker, his clothing and his vehicle.
That description changed everything. Within approximately 30 minutes, police located Robbins.
When a state trooper stopped him on Route 219, Robbins ultimately shot himself in the mouth with a .357-caliber handgun rather than face arrest. He was 53 years old.
Inside the rental vehicle Robbins had been driving, investigators found items that immediately raised more questions: duct tape, plastic fiber rope and two guns.
Robbins was dead. But the investigation into him was just beginning.
Who Was Gary Robbins?
Robbins wasn’t some mysterious drifter passing through Western Pennsylvania. He had lived in the Pittsburgh area, including Murrysville and Squirrel Hill, and had worked in real estate and insurance.
That ordinary appearance made what investigators began uncovering after his death even more disturbing.
Authorities started comparing Robbins to unsolved murders, disappearances, kidnappings and sexual assaults involving women. Investigators in Pennsylvania, Ohio, Maryland and Michigan eventually suspected that Robbins had been a serial sexual predator and killer.
The frightening question became: How many women had Gary Robbins attacked before Mary Ann Marker survived him?
A Butler County Woman Survived Him Too
Marker wasn’t the only woman known to have survived a horrifying encounter connected to Robbins. Authorities identified Robbins as the man responsible for abducting a Butler County woman in 1982.
According to reports, the woman endured approximately 24 hours of captivity, during which she was sexually assaulted, beaten and burned. She survived after being dumped over an embankment in Greene County.
The attack provided investigators with another example of the extreme violence Robbins was capable of committing.
But there were women who didn’t survive.
The Murder of Christine Campbell
Authorities in Jefferson County, Ohio, linked Robbins to the death of Christine Campbell, a 36-year-old woman from Chester, West Virginia.
Campbell’s body was discovered in a rural ditch on July 4, 1987. She had been blindfolded and bound and had been shot multiple times. Former Jefferson County Sheriff Fred Abdalla later publicly linked Robbins to Campbell’s abduction and murder.
Investigators noticed disturbing similarities in the way Robbins allegedly targeted and restrained women.
And Campbell wasn’t the only homicide they began examining.
Was He Responsible for Murders Across the Country?
After Robbins’ death, investigators began looking at him in connection with unsolved cases stretching well beyond Pittsburgh.
Among the cases in which Robbins became a suspect were the 1983 killing of Nancy Pucci in Bel Air, Maryland, and the 1984 murder of Sue Clason in Reed City, Michigan. Authorities also examined whether Robbins could have been responsible for killings in Western Pennsylvania during the 1970s.
But one Pittsburgh case stands out.
The Unsolved Murder of Carol Jursik
In July 1979, Carol Jursik was a 24-year-old Penn State graduate student living in Squirrel Hill. She was also an accomplished fencer who had been nationally ranked and was considered a possible contender for the 1980 U.S. Olympic team.
On the evening of July 30, Jursik went jogging with a housemate. They eventually separated, and Jursik stopped at a Giant Eagle on Murray Avenue.
She never made it home.
Her grocery bag was later discovered only a short distance from where she lived. Days later, her body was found in Frick Park.
Her murder remains unsolved.
Years later, after Robbins died, investigators began examining whether he could have been responsible. The geographical connections were difficult to ignore.
Robbins had lived in the Squirrel Hill area. His own vehicle was reportedly found near the location where Jursik had disappeared nine years earlier.
That did not prove Robbins killed Carol Jursik. But it was enough for investigators to take the possibility seriously.
More than four decades later, Jursik’s murder remains one of Pittsburgh’s haunting unsolved cases.
The Washington County Murders
Robbins was also investigated in connection with a series of killings involving women in Washington County during 1976 and 1977.
Western Pennsylvania investigators had already wondered whether some murders of women during that period might have been connected. After Robbins’ violent history became known, his name naturally became part of that investigation.
Again, suspicion is not proof.
Robbins died before detectives could interrogate him, prosecutors could present evidence against him or a jury could determine his guilt in those killings.
That distinction matters.
Some crimes were directly connected to Robbins through survivor identifications and investigative evidence. Others remained suspected connections.
Mary Ann Marker May Have Stopped Something Much Bigger
That’s what makes Mary Ann Marker’s survival so important.
Robbins apparently expected to leave her unable to identify him. Instead, after being shot in the face, Marker remained composed enough to give police the information they needed to find him. Her description led police directly to Robbins. Had Marker died that afternoon, investigators might never have connected Gary Robbins to the attack.
He might have driven away.
And if authorities’ suspicions about his history were correct, there is no way of knowing whether another woman would have been next.
Years later, Marker said she believed God had been with her that day.
Considering what happened afterward, it’s difficult not to understand why she felt that way.
A Pittsburgh Story Few People Remember
Gary A. Robbins isn’t a household name. There aren’t endless documentaries about him. His name isn’t mentioned alongside Bundy, Dahmer or Gacy.
Yet his story sits right in Western Pennsylvania’s backyard.
He lived in Murrysville. He had connections to Squirrel Hill. He was identified as the attacker in horrific crimes against women.
Authorities linked or suspected him in cases stretching through Pennsylvania, Ohio, Maryland and Michigan.
And because Robbins killed himself before he could be questioned, one question may never have a definitive answer: How many victims were there?
There is an important responsibility when telling a story like this. Robbins should not simply be declared responsible for every unsolved murder investigators examined after his death. Suspicion isn’t a conviction, and the families of victims deserve more than speculation presented as fact.
But what authorities knew about Robbins was disturbing enough.
A man who appeared to live an ordinary life around Pittsburgh was capable of extraordinary violence. And it took the courage and presence of mind of a woman who had just been shot in the face to finally bring his story into the light.
Mary Ann Marker survived Gary A. Robbins. In doing so, she may have prevented another woman from becoming his next victim.
