EL DORADO HILLS --
The theft of thousands of dollars of equipment from Oak Ridge High School Sunday morning had staff members searching security camera video for clues.
El Dorado County Sheriff's detectives say five welders and two plasma cutters were taken from the engineering program. One of the units is valued at over $10,000.
In addition, a football trailer was hitched up and driven off. The trailer contained medical bags and the program's stadium camera system worth tens of thousands of dollars.
"You put your heart and soul into a program, and then you see all this taken away. I kind of take it personal," said Bob Wilson, the founder of the school's acclaimed manufacturing engineering program.
Sheriff's investigators posted blurry still pictures of the suspects taken from the school's security video cameras.
But campus maintenance supervisor Jamie Schanrock came in on the Martin Luther King holiday to search through videos from the schools numerous cameras, which investigators have not seen and which were shown to FOX40.
He found the spot where the thieves hopped over a wall of the shop enclosure and found one of the missing welders. He also found video of the thieves returning a half hour after in what appears to be a white Ford Expedition, driving off with the football trailer.
They were driving a small two door sedan. Thieves made several trips to the shop area to retrieve welders that they had left behind before driving off.
"...and then to get in another car and come back, they live right around here," said Schanrock.
Another discovery by Schanrock was what appears to be a man who was hiding in the shrubbery who went into hiding when the burglars came back a second time. Schanrock and Wilson don't know why he was there, but feel he could be an eyewitness if he's found.
Wilson feels that the thieves had inside information. He doesn't suspect a student but says he often has visitors to his program.
"They knew exactly what we had, so it's probably somebody that I have seen or my students have seen that have come in here, recognized what I had and figured it was an easy take," said Wilson.
The video wasn't clear enough to get license plate numbers but the school is hoping they can find a program that could enhance the video.
Detectives say people can call them at (530) 621-6600 if they have any information on the case or if they recognize anything in the pictures that have been posted on the El Dorado County Sheriff's Facebook page.
