Tampa, Florida - Detectives call it one of the most unique crimes they've ever seen.
"Unique" and "greedy," says Tampa Police Officer Colin McCoy.
Officer McCoy is currently working on this case, and one of the biggest clues he has so far is crystal clear surveillance video, showing three teenagers rigging a change machine at Tampa Coin Laundry on Martin Luther King Drive.
The teens are caught on camera taking a $10 bill with a string attached and shoving it into the device to where it advances the rollers inside, releasing quarters.
And the "bonus?" At the last minute, the teens yank the bill back just in time to use it again.
"They've figured out something that's worked for them," says McCoy.
It's worked, but for how long?
The teens started back on May 17th. And, cops say, the kids didn't stop until the 19th. They did it over and over and over again.
In the end, they took away just over $1,195.
"They've figured out how to make a quick buck, and they'll keep doing it until it runs out," McCoy told us.
McCoy believes this isn't the first time the teens have done this. They think its happened at other businesses as well.
The officer admits, "I know they've done this before. They're too good at it."
The teens are seen driving up to the laundromat in a truck that detectives are hoping someone will recognize.
In fact, the faces of the suspects are all over surveillance. One of them has strawberry blonde hair - a trait that cops hope will ring a bell with someone who sees the video.
Another suspect is seen using his left hand during the crime, another recognizable characteristic.
Cops say the surveillance cameras could be the key to cracking the case. More than a dozen line the walls inside and outside the building.
One of the young men actually stands next to the "ringleader" paying close attention to the crime taking place in front of him.
"They're trying to learn. You can see them teaching each other," McCoy says.
Police say that anyone who knows the suspects seen on surveillance can get $1,000 for giving information to Tampa Police.
You don't even have to leave your name. It's all anonymous.
