When he couldn't get help from police, Joshua Kaufman went online and used Twitter and a blog to help track down his stolen laptop.
His efforts were successful and the computer was returned Wednesday - the latest example of people, not police, using technological tools to help find their own stolen property such as cars, cell phones and digital cameras.
It helped that just before the laptop was stolen, he had installed theft-tracking software.
The images from that software that arrived in his inbox were grainy, low-lit and intimate: a man curled up on a couch, sound asleep; the same man propped up against pillows on a bed, shirtless.
Kaufman took the images to police, who did not help him. So he went online, publishing the pictures on Twitter and in a blog titled "This Guy Has My MacBook."
