TRAVIS COUNTY, Texas — Family members and friends of a man who disappeared while swimming in Lake Travis on May 5 are continuing their search and asking for the public's help.

Manuel Salas, 53, of Elgin, was swimming by a boat near Mansfield Dam Park when his wife called 9-1-1 and told dispatchers he went underwater and never resurfaced, according to the Travis County Sheriff's Office.

Salas' family told KVUE Salas and his wife had been married for two months.

"That's the last we've seen and heard of him," Salas' brother David told KVUE.

After sonar and dive teams called their search off a week after Salas' disappearance, his family and friends have been searching the shore and water as often as they can to find his body.

"He's still out there," David said. "He's missing, so we're really wanting to find him and put closure to this."

The days following Salas' disappearance have been difficult for the family.

"It's been devastating. It's tragic," David said. "He's a great person. It's just something that shouldn't have happened."

Salas was no stranger to the water, according to David. His military training made him a great swimmer.

"He knew waters. He knew what he was getting into," David said. "We were very shocked and surprised when this happened."

Joe Angel Zamarron, a coworker of Salas for more than 15 years, was just as surprised when he heard the news of Salas' disapperance.

"I saw him every day, Monday through Friday, in the morning," Zamarron said. "It's just strange going [to work] every day and knowing that I'm not going to see him again."

Zamarron was one several coworkers who came by the park Saturday afternoon to offer support to Salas' family.

"It's like a void, and it's noticeable. We're going to miss him," Zamarron said.

There were no signs of Salas during their search Saturday, but his brother is hoping the public can help keep an eye out.

"If you see something, know something," David said, "just report it."

Salas' family told KVUE they are looking for volunteer divers who can get in the water and help search for his body.
