Witness in Utah trial say more surveillance videos may exist of Oklahoma City bombing

A police officer who was at the scene of the 1995 Oklahoma City bombing says he saw surveillance cameras at the federal building that may have recorded the attack.

Former Oklahoma City police officer Don Browning testified Wednesday he saw FBI agents taking cameras off the federal building.

Browning acknowledged he doesn't know if the cameras were operational.

The trial in Utah will decide whether the FBI must do additional searches in its archives for security camera videos.

A Utah man believes video exists that would show a second suspect. Jesse Trentadue says his brother bore a striking resemblance to a police sketch released after the attack of a second suspect. His brother was flown to Oklahoma several months after the bombing, where he died in a federal holding cell.
