A 17-year-old Brooklyn teenager is missing an arm, and a 39-year-old man is facing attempted murder charges. This is the result of a horrific scene in New York on Friday that unfolded from a seemingly routine Craigslist transaction.

The 39-year-old man known only as "Phil" is a regular buyer and seller of sneakers on Craigslist. He agreed to a sale with the teenager and the pair met in the middle of the day on a busy street. It's here that things went wrong. Climbing into Phil's SUV, it's reported that the 17-year-old pulled a gun on the man, took the sneakers and walked off.

Rather than calling the police, Phil took things into his own hands. He did a quick u-turn and ran over the teenager attempting to walk away with the sneakers. The thief's arm was severed in the collision, but adrenaline caused him to run off, with one arm, before collapsing outside his house.

The boy is in stable condition and doctors plan to reattach his arm, while Phil is facing charges.

Let this story be a reminder: Craigslist can be amazing, and horrifying. If you're going to conduct a transaction you should consider the site's safety tips.
