ROBSTOWN - Texas Department of Public Safety is investigating a fatality crash that killed three teenagers and left one in critical condition. The accident occurred Sunday, at 2:03 p.m. on U.S. Highway 77 about a half-mile south of Robstown.

Jade Sherriod Robinson, 17, a rear seat passenger, and her sister Brianna Rachael Robinson, 19, both residents of Houston, Texas-rear seat passenger of the Hyundai were pronounced dead at the scene.

The driver of the Hyundai and front seat passenger were both flown by Halo Flight to CHRISTUS Spohn Memorial Hospital in Corpus Christi with life threatening injuries. Brittanie Tashay Johnson, 18, a resident of Houston, Texas, a front seat passenger was pronounced dead at the hospital. The driver of the Hyundai is in critical condition in Intensive Care Unit at Spohn Memorial Hospital.

Distracted driving by use of cell phone as a GPS is the factor in the crash, DPS officials said.

Preliminary investigation revealed a 2013 Hyundai Elantra (occupied by four teenage girls - including the driver) was traveling north on U.S. 77 in the left lane. A 2009 Freight liner truck tractor (occupied by the driver only) towing a flatbed trailer was traveling south on U.S. 77 in the right lane.

The driver of the Hyundai drifted into the center median and overcorrected multiple times before losing control of the vehicle and spun across the center median striking the Freight liner truck tractor on U.S. 77 southbound in the right lane.

The Hyundai, occupied by the four teenage girls was traveling back to Houston from South Padre Island on Spring break back vacation.

The driver of the freight liner truck tractor was not transported to the hospital.
