Eric Keng had a very bad Tuesday night. The 20-year-old college student is behind bars after he smashed a driver's windshield with a golf club, tried to carjack two people, successfully carjacked a third and tried to rob a convenience store at gunpoint. He was waving a gun and demanding “one of everything” before an employee recognized him as a regular customer. Then he led police on a 10-mile chase through the streets of Dallas in the stolen vehicle before he crashed into a guardrail. He then tried to run away from the scene, but was caught by officers and pepper sprayed. Now, in a jailhouse interview, Eric says "I think I was drugged." He believes a friend tainted the C4 (a bodybuilding supplement) he took before he went on his crime spree, ended up with an awesome mugshot and behind bars.
