OMAR Satanic Arsonist Mystery

Broadcast on Unsolved Mysteries. The Case of the Satanic Stockton Arsonist.
On August 15, 1989, an overheated car pulled to the side of a road in Stockton, California. The owner was a man we’ll call Joseph Villa. Joseph inspected the damage while his wife and son looked on. He decided that he and his son should walk to the nearest phone. On the way, they noticed a camouflage jacket on the ground. Inside a pocket was an unlabeled videotape.
Joseph and his son decided to take the video home and watch it. The video was of a house on fire. The family immediately turned it over to police, who were convinced that the person holding the camera had also set the fire. Captain Frank Curry of the California Department of Forestry assumed the disturbing voice heard on the tape belonged to the arsonist:
Update:

Within minutes of our broadcast, several viewers called and identified the house seen burning on the videotape. It was located in Redwood City, California, 80 miles west of Stockton. The house that was destroyed was under construction at the time. Today it has been rebuilt. Surprisingly, on the night of the blaze, Woodside Fire Captain John Dellinges also videotaped the fire:

“While I was setting up the command post, directing companies to extinguish the fire, I had set up my video camera to film the fire for training and investigation purposes.”

By comparing Captain Dellinges’ tape with the video shot by the arsonist, investigators were able to confirm that this was definitely the fire’s location. According to Detective Mark Pollo of the Redwood City Police, authorities had two suspects:

“Some of the calls received led us to a 17-year-old Woodside youth. We interviewed that youth. Through that interview, it led us to a 19-year-old Redwood City youth who was arrested and interviewed and subsequently admitted to burning the house, taking the video and was the one who talked on the videotape.”

Both suspects were underage when they set the fire and were tried as minors. One served time at juvenile hall. The other was committed to a state mental hospital.
The haunting last words on the arsonist's video were:
"Good Night, Ladies and Gentlemen. YOUR HOUSE IS NEXT!"
