TAMPA, FL – Police arrested two teenagers for killing a man during a Craigslist transaction.

Authorities arrested Ramontrae Williams, 16, and Dontae Johnson, 17.

Detectives say James Beck agreed to meet Williams and Johnson after they told him they were interested in buying his son’s dirt bike, which they saw in an ad on Craigslist.

Beck took his 15-year-old son along for the transaction on Wednesday, according to Fox 13.

But Beck realized Williams and Johnson didn’t intend to buy the bike, instead they wanted to rob him, police say.

As Beck tried to leave, police say Johnson shot him and Williams stole the dirt bike.

Williams and Johnson were both arrested.
