Austin police say Mark Conditt was behind five explosions in March that gripped Texas' capital city, killing two people and injuring five others.
Helicopter video, released Friday as part of a meeting with Texas Department of Public Safety commissioners, shows law enforcement officers closing in on Conditt on an I-35 frontage road following a March 21 police chase.
As officers approach Conditt's vehicle, a flash of fire erupts from the car.
"Got an explosion! Got an explosion inside the vehicle," a DPS officer can be heard saying on the video.
