Witness Frank Romo says, "The dog jumped in I guess to try and rescue him and everybody else just pretty much panicked and were in disarray of what had happened. I guess they just couldn't believe it was happening. When he went under, he never came back up. And it was just seconds, just seconds was all it took."

According to Roger Wade with the Travis County Sheriff's Office, Todd Mobley, 48, was staying at a family vacation home on the Pedernales River over the weekend.

Around 11:15 p.m. on Saturday, Mobley was seen swinging from a rope at a dock. Witnesses say he did not resurface after a second attempt at swinging into the water.

Search efforts were initiated late Saturday but officials called off the search and began a recovery effort at daylight Sunday.

Mobley's body was found by divers shortly after 9 a.m. in 14 feet of water, nearly 50 feet from the dock.

Wade says the death is being investigated as accidental at this time. Toxicology results will be ready in six to eight weeks.
