It all unraveled when detectives traced the signal to the "hot" Xbox 360 and made an arrest.
Pelham police uncovered more than $5,000 worth of stolen video games, cell phones and designer duds.
Detectives say 22-year-old Jeremiah Gilliam stole the Xbox 360 from a home in the village.
But instead of selling the hot item, detectives say the suspect kept it for himself.
"Our victim, a kid, the day after the burglary, went online and realized he's online. He told his mom and dad," said Detective John Hynes.
Pelham police say the suspect was playing the Xbox 360 online. They were able to get the computer's IP address. Then, all they needed was a search warrant to go in and make the arrest.
Detective Hynes says Gilliam even greeted them as he walked out of his Laconia Avenue home.
The Bronx man had no idea police were tracking him, allegedly watching him play all the new games on the stolen Xbox.
Investigators say they found all kinds of stolen goodies in Gilliam's bedroom Tuesday afternoon.
"While we were in the room, we found the Xbox games, Nintendo games, GPS units, cell phones. We have over 55 articles that we removed," Hynes said.
Police say Gilliam and an alleged burglary team may be connected to nearly 200 car larcenies and burglaries throughout Westchester.
Detectives believe the team stayed near highways in Pelham, Eastchester, Tuckahoe, Scarsdale, White Plains, New Rochelle and Yonkers.
Police are working on making other arrests.
They point out people need to extra careful around the holidays.
"Don't make it easy. Lock your car. Make it more difficult for them to into the car," Hynes said.
