The truck kind of flipped. I  just panicked, I called 911," said a witness who declined to give her name. She had been driving by with her two children in her car. "My first thing, I thought, it's explosive, you know, a suicide mission bombing at the FBI building, and there's the gas station (nearby)."The Pittsburgh police bomb squad searched the dump truck and found there was no explosive.Nonetheless, the FBI described the damage to the gate as, "pretty significant.""He drove over the barrier, broke our barrier," Heeb said.Ross was taken to UPMC Presbyterian, where police said he tried to escape from custody as he was being transferred to a police cruiser after his hospital visit."Locally, Ross faces numerous charges including aggravated assault, recklessly endangering another person, fleeing and eluding, and various summary driving offenses," said a statement emailed by Pittsburgh Public Safety spokeswoman Emily Schaffer.U.S. Attorney David Hickton announced later Tuesday that federal charges have also been filed in connection with the intentional destruction of the security gate.

He never saw an agent and left without further incident," the criminal complaint read.Police said they found multiple identification cards on Ross bearing his name but with different addresses, including two in Trafford, one in Ohio and one in Florida.Police also said they found a motel key marked "#15" on Ross.According to the criminal complaint, the damage to the FBI facilities tops $350,000.
