Schmidt remains in the burn center at the University of California San Diego Hillcrest Hospital.

An exposed gas line appears to have caused the fiery training accident that engulfed the armored vehicle according to the Washington Post.
The Amphibious Assault Vehicle (AAV) had pulled off the road in what is known as a "herringbone" formation.
While completing the maneuver, the vehicle seems to have busted a gas line, severing the pipe with its tires, the official told the Washington Post. Somehow, a spark hit the gas leak, igniting a blaze under the AAV.
Camp Pendleton is a U.S. Marine Corps base located north of San Diego.
A Pendleton spokesman said the vehicle has been used to transport Marines from sea to land since the 1970s.
