Arizona - -( In this highly unusual case in Tunnelton, PA, all the action was all caught on video.  The gun shop owner, Frank Petro, knew his killer and former officer, Jack O. Edmundson.

A Family members said that Edmundson had been extorting Petro by impersonating a state lottery officer.  The scam was that Edmundson claimed that Petro’s winnings were fraudulent, and that he would jail Petro unless Petro paid him the winnings.   Petro, as a highly regulated gun shop owner, was particularly vulnerable.  Even an accusation might have resulted in the BATFE pulling his license and livelihood.   When Petro’s brother read a newspaper article where Edmundson was prosecuted for impersonating an officer, Petro contacted a lawyer to see about recovering the $130,000 that he had already paid Petro.

It was at this point that the attack occurred.  From

The video footage shows that Edmundson entered the shop, reached behind the counter and grabbed a small-caliber gun that he used to shoot Petro following a brief argument.

The attack seems to have been premeditated.  Edmundson was wearing what appeared to be blue latex gloves under his winter gloves.  After shooting Petro, Edmundson is seen to be spreading black powder and an accelerant that he brought with him, around the shop and  over Petro’s body.   But Petro still had fight left in him.  From

“He lays there three minutes and appears to be unresponsive,” before he tried to rise, “and the video clearly shows Mr. Edmundson kicks him in the face and knocks his glasses off,” Valyo said.

The men went to a hand-to-hand scuffle and Edmundson seemed to try to shoot again, but the gun apparently malfunctioned before “he cleared it,” Valyo said.

The fight went on several minutes “until Mr. Petro started to lose his strength. They fell behind the display case,” Valyo said. “And although you can’t see the muzzle flash, it appears this is the time Mr. Edmundson was shot.”

Edmundson manges to prevail over the gun shop owner, who had been shot twice and was 62 years old. He then shoots Petro twice more to finish him off.

State police believe Edmundson’s plan was to set fire to the store, but he was shot in his right thigh during the second scuffle with Petro and telephoned 911 for help, according to the criminal complaint.

Edmundson might have got away with the crime, but after he was shot, he could no longer set fire to the gun shop. He claimed that he had to shoot Petro in self defense, but the video showed a different story. The story did not say if the video was uploaded to an off site storage facility, but the story would be a good advertisement for such a capability.

The shooting occurred on 31 December of last year. At the preliminary hearing,  on Friday, Edmundson was in a wheelchair.

After listening to about an hour of testimony, Indiana District Judge Guy Haberl ordered Edmundson to stand trial on counts of first-degree murder, arson and aggravated assault.

Incredibly, an anti-rights blogger at is claiming that if only Frank Petro, the gun shop owner, had not had any guns, he would have been better off. They spout the usual false talking points:

Every life is precious, but multiple studies show that a gun is far, far more likely to cost you your life than to protect you, as Mr. Petro and others have found out.

Frank Petro did not survive the attack, but by fighting back, he started the chain of events that resulted in the arrest of Edmundson, and will likely remove a very dangerous predator from society.

    1. well it seams that this Edmundson person is going to have a long time to think about what he did and why. It is this reason that shop owners should BE allowed to own and keep a firearm close by. I have known a few shop owners that have had to use a gun to protect not only the shop but lives as well. A gun in the right hands can not only save you from a thug but it can also send a message to the others that might try the same thing.

    2. Your title says “former officer”, but your article doesn’t say anywhere that he was in fact an ex-officer, only that he impersonated an officer in the past. Good Police Officers get enough bad press from the 10 percent that are bad, we don’t need to add more with identifying impersonating officers with real officers. Most Police are honorable, honest and professional. The few that are not, give us all a bad name, and as a result, make our job that much harder.


    4. I am a bit confused: why is an Indiana judge presiding over a Pennsylvania case?

      Tsgt, this happened in Indiana County, Western Pennsylvania.

      I worked with this clown before he managed to talk his way into a job as a police officer. Jack Edmundson was a paramedic in Indiana County Pennsylvania, and always behaved as if he were the cool kid on the block and generally behaved like a prick toward anyone who wasn’t awesome enough to be his friend.

      He then worked as a cop in Quarryville, PA, and then Lancaster, PA before he was caught multiple times stealing evidence and other things belonging to victims and suspects.

      BTW, Jax, save the “few bad cops” routine for another venue. There is no more denying that there is an overall insidious problem with law enforcement and the allegedly good cops will have to effect a remediation from within or it will overall turn out poorly for you all.
