30 MacBooks are on their way back to the classrooms of the high school.
In all, 60 computers were stolen from the school on February 21st and police have arrested two 17-year-old boys for the crime.
One of the suspects is a student at West Philadelphia and police say he knew what rooms to hit.
Their downfall began last week when a 23-year-old man from Montgomery County watched the crime report on the 11 o'clock edition of Action News and immediately called police.
Earlier, he'd seen a MacBook advertised on Craigslist and met the seller at 59th and Sansom streets. He paid $400 for the computer.
The computer matched with one stolen from the high school.
Police then set up a sting by going on Craigslist and luring one of the teen sellers to 52nd and Market streets where they busted him.
The investigation led to the home of West Philadelphia High student 17-year-old Jonathan Carter where police say 28 more stolen laptops were found.
"They were cleaning the hard drives and taking the stickers off to make it look like they weren't stolen from the school district job," Philadelphia Police Lt. John Walker said.
17-year-old Dadisi Williams from University City High School was also arrested.
At a second location, police say they recovered a computer stolen back in late December from West Philly High.
"The younger generation is learning a lot quicker. Technology, although it's great, it's allowed a lot of information to go out there every day, and these kids are getting better at what they do," Walker said.
30 laptops are still missing, believed to have been sold, held elsewhere, or in circulation on the street.
The 30 laptops are valued at $40,000.
Adults at the home of both suspects had no comment on the case today.
Both teens remain in the juvenile detention center facing charges including burglary and theft. Police say both have been arrested for theft before.
