Margaret Gil // Cameron County Jail

Margaret Gil sat behind the wheel of her 2006 Toyota Rav4 even though she was allegedly intoxicated on the morning of Sunday, June 30.

Gil was driving when she allegedly crossed the clearly marked solid lines around 10:15 a.m. on Highway 100 and slammed her Rav4 carrying her passenger Carmela Sanchez into a 2013 red Toyota Corolla carrying a 13-year-old, a 3-year-old and her parents.

According to court documents obtained by Action 4 News, her blood alcohol concentration (BAC) was well above the legal limit to be behind the wheel.

In Texas, it is against the law to be driving with a BAC above 0.08 percent.

According to the documents, Gil, the sole survivor TMs BAC was checked at the hospital 44 minutes after the officer was displaced to the scene of the accident.

Gil TMs BAC was 0.192, over twice the legal limit to be driving a vehicle.

Gil allegedly admitted to a Department of Public Safety (DPS) officer that she was the driver behind the Rav4 and a witness caught the scene of the crash on his cell phone as evidence.

Yesterday, DPS confirmed that five counts of intoxicated manslaughter would be added to her five counts of criminal negligent homicide.

Gil is behind bars at the Cameron County Jail and her bond is set at $2.5 million.
