UPDATE: 3:35 p.m.

Ford Hood officials did not give the identify of the missing driver in a press conference Thursday morning but did say the driver is a man.

Close to 80 people continued the search, according to Deputy Director of Emergency Services, Christopher Zimmer.

Zimmer said the vehicle, a red Ford, was found with its windows broken. He said the search will continue Friday if the man is not found.

Search and rescue crews further increased their search effort Thursday morning, after deploying additional soldiers Wednesday to find the missing driver who was swept away in Clear Creek near Turkey Run Road just before 6 a.m. Tuesday.

Water levels were lower Thursday, allowing teams to access more locations that were previously flooded out from Tuesday's storms. In response, more ground and canine search teams were deployed, and more boat crews were launched from staging sites on Turkey Run Road and West Range Road, Fort Hood said.

Search teams combed both land and water areas downstream from where the driver vanished. The search zone encompassed several miles, as of Thursday, Army officials said.

Emergency crews have used a deliberate search pattern that was based on analysis of topography and meteorological conditions, a Fort Hood official said, adding two AH-64 Apache Helicopters were searching by air. A UH-60 Blackhawk medical evacuation helicopter was also flown to the staging area, where it stood ready to respond as soon as the missing driver was located.

The vehicle the missing person was operating was located Wednesday. Authorities said they knew the identity of the vehicle's registered owner, but they had not publicly released the individual's name nor confirmed if the owner was also the missing driver.

A media updated on the search progress was expected at noon on Thursday. Channel 6 Military Reporter Jillian Angeline will be there. You can follow her on Twitter for breaking updates, which will also be posted on KCENTV.com.
