A preliminary investigation found that a Jeep Grand Cherokee was traveling on Interstate 10 when, for reasons that remain under investigation, it veered onto the improved right shoulder and struck the rear of a trailer being towed by a semi-truck. Troopers said the semi-truck and its two trailers were parked on the shoulder because of mechanical problems.

The driver of the Jeep, 54-year-old Carlos Mugica IV, and his passenger, 46-year-old Jennifer Salazar Mugica, were pronounced dead at the scene. Both were Castle Hills residents.

The driver of the semi-truck was not injured.
