GALVESTON -

Testimony was set to get underway in a hearing Monday afternoon that intended to find out who was responsible in the devastating oil spill back in March.

168-thousand gallons of oil leaked into the water near Galveston Island, after two boats collided in the Houston Ship Channel.

The United States Coast Guard conducted the hearing as part of its marine casualty investigation into the incident.

The hearing was scheduled to begin at 1 p.m. at the Galveston County Criminal Justice Center. Officials expected the trial to wrap up by Friday.

During the trial, the board will examine the cause of the accident and make recommendations to avoid similar incidents in the future.

Meanwhile, the National Transportation Safety Board is investigating whether civil and criminal charges should be filed.
