Prosecutors dropped a felony charge Tuesday against a Vinson & Elkins practice leader who authorities said abandoned injured passengers after a boating accident on Lake Travis last year.

Authorities said that Douglass McWilliams, head of the equity capital markets practice at Vinson & Elkins in Houston, was at the helm of a boat that crashed into a sandbar on the Austin lake. According to the Austin American-Statesman, McWilliams told his injured passengers that he was going to get help. When McWilliams wasn’t seen for several hours, authorities initiated a search of the water that included the use of an Austin police helicopter, according to the Statesman.
