Jacob Cox-Brown is not smart.
The Oregon teen was jailed following the dumbest Facebook gaffe of all time - and that's saying something, as 95 percent of all Facebook posts could be considered dumb.
His blunder? Bragging about driving drunk AND committing a hit-and run.
"Drivin drunk ... classsic ;) but to whoever's vehicle i hit i am sorry. :P" was the early-morning post that quickly led to his arrest at home in Astoria, Oregon.
Upon reading Jacob Cox-Brown's post, two of the his Facebook friends contacted police; it became vital information in an ongoing investigation - go figure!
The previous night, two officers responded to an incident in which a white Scion and an adjacent vehicle were damaged in their parking spots.
After collecting pieces of a damaged taillight and bumper, police were informed about the Facebook post and headed over to the home of Cox-Brown.
They arrested him on two counts of failing to perform the duties of a driver. No DUI charge was filed as nine hours had passed and he was not in the car.
"Astoria Police have an active social media presence," a spokesman said.
"It was a private Facebook message to one of our officers that got this case moving, though. When you post, you have to figure that it is not going to stay private long."
"We actually use Facebook to find things not unlike this."
At 18, he can be charged as an adult; surprising, as he clearly has the IQ of a three-year-old. Too bad there's no surcharge for social media stupidity.
