Everything from motorcycles and power tools to chopped-up trailers and pickup truck parts stashed behind the red corrugated fence at 1833 Spearing St. appears to have been stolen from people over months or even years, according to police working to catalog the recovered items.

Police arrested two men Tuesday on grand-theft charges after a tip led them to the sprawling yard off Eighth Street where the found an already-disassembled video display trailer - valued at $150,000 - when it was stolen Jan. 21 from PRI Productions on Kings Avenue.

As Lt. Ron Norse walked past boats, golf carts, lawn mowers, tools and other items, he said their next step is to find the owners. Police will post photographs of the most valuable items on the Sheriff's Office's Facebook page and ask potential victims who recognize their property to call them at (904) 591-6210.

"We have [identified] 15 victims and there are more coming," said Norse, the automobile crimes unit commander. "... If you believe that you see something that belongs to you, please be prepared to show proof of ownership in the form of a police report or receipt. But please call before you come, and if you don't see something that belongs to you, call us and let us look around."

As he looked at the yard full of stuff including a playground-sized playscape, Larry Hamilton hoped he was one of those. He said his trailer was stolen from his home in September, joining a rash of motorcycle, trailer and boat thefts in his Northwest Jacksonville community. He said the white pickup truck seen on security video of his theft matches the one seen stealing PRI's trailer. Police alerted him that his trailer could be in the yard, but they weren't hopeful.

"They said if it is, it's cut up and gone," Hamilton said. But he feels good "knowing that it is over, knowing that it has been stopped."

The discovery of what police said is probably a combination theft and chop-shop ring started Thursday when PRI Productions' trailer, with a huge pop-up video screen, was stolen. Video surveillance showed a white pickup truck with roof-mounted running lights pull up, then hitch up the trailer and head down Kings Avenue.

"We received a citizen's call thinking they saw the trailer and vehicle here on Spearing Street on Monday morning," Norse said. "We responded here and we did locate the vehicle."

The Chevrolet truck was in the yard with a trailer reported stolen from a Mandarin business in the past week and a picnic table stolen Monday from a nearby business on Hood Road inside it, police said.

Police got search warrants and found Guy Charles George, 33, asleep in a rear bedroom with a gun nearby, Norse said.

Property records show Guy is the homeowner. He was arrested on three counts of grand theft over $100,000 and remains behind bars on $300,000 bail, according to jail records. Also arrested there was James Wesley Walker, 25, on two counts of grand theft. He's in jail on $200,000 bail.

Officers then began cataloguing everything in the yard and house and found numerous trailers that had been stolen or had their ID numbers removed, including one with wheels and hitch cut off. Other items included a stolen trailer-mounted barbecue smoker, along with pressure washers, expensive compressors, new sandblasting gear and four high-end rifles that could belong to someone else, Norse said.

Norse said this shows the value of having photo-documentation of all valuables, with the serial number recorded.

"And if the item doesn't have a serial number, engrave the last five of your Social Security number, ... something that can show proof that the item belongs to you," he said.

Police think the theft ring worked all across Jacksonville and possibly into neighboring counties, and don't know how long investigators will be on scene cataloguing items.

Anyone who thinks their stolen items are among the goods found by police at the yard on Spearing Street can call the Sheriff's Office at (904) 591-6210.
