Authorities say a fisherman found the body of Kent Zavala.
Zavala went missing Sunday night after he was ejected out of his vehicle during a major three-vehicle crash.
The Coast Guard's search was suspended on Monday, pending more information, but Texas Equusearch continued to look for him.
The Coast Guard said a Jeep with three men and a dog inside crashed into a guardrail on the outbound lane of the causeway near the Tiki Island exit.
Two of the men were taken to UTMB with critical injuries. The Coast Guard said a dog and Zavala were ejected through the soft top of the Jeep and into the water.
Boaters were able to rescue the dog.
