A workboat sunk in the La Quinta Channel around 11 a.m. Friday.
The Blanks went down in the Corpus Christi Ship Channel near Ingleside. No passengers were aboard the unmanned boat.
A U.S. Coast Guard representative told KRIS 6 News no search-and-rescue efforts are underway, and it doesn't believe the incident resulted in any pollution to the area, which has been marked off with buoys.
Crews are in the area investigating the cause of the incident, and what needs to be done to remove it from the channel.
This is a developing story. Check back with KRIS 6 News for updates.
