Austin's former police chief and Houston's current police chief -- Art Acevedo -- got choked up when he confirmed to the media Tuesday that the body of an officer who drowned in his car had been found. That officer died Sunday morning trying to get to work.

As Houston officers sacrifice their lives to help those affected by Hurricane Harvey, Williamson County Sheriff's deputies are in Houston performing dozens of rescues along with Cedar Park police, Leander police, Austin police and Austin firefighters.

KVUE's Ashley Goudeau made it out to East Houston Tuesday morning to meet up with Williamson County Sheriff's deputies. Along the way, fuel tankers and other vehicles were stopped on the highway -- drivers had to abandon their vehicles to escape flooded lanes. Some resorted to turning around and driving in the opposite direction on the lanes.

The deputies from Williamson County have been working to rescue people from flooded homes in East Houston. The brave first responders have described the rain as relentless, saying the rescues were even more challenging because the rain just never stopped.

"We had an older gentleman, a quadriplegic, that had some issues in a wheelchair," said Lt. James David of the sheriff's office. "The National Guard assets were actually there. They came up and helped us out. We were able to get him through there without getting any of his extremities wet luckily."

In addition to National Guard members, retired service members are also helping out. These servicemen -- and their equipment -- are from the United States Armed Forces Museum that's nearby in Houston. They came out of retirement and took the vehicles off display to help with rescues.
