HARRIS COUNTY, Texas (KTRK) — The Harris County Sheriff’s Office is investigating a fatal crash where a mother and her child were ejected from a vehicle in east Harris County on Sunday.

Deputies were dispatched to the single-vehicle crash at about 1:45 p.m.

Authorities say that the driver lost control of the vehicle which rolled over several times, leaving a long trail of debris.

Sheriff Ed Gonzalez said the major crash involved a family of five, including a 25-year-old mother, a 26-year-old father, and three small children, ages 2 and 6 years old, and a 4-month old.

Officials say that neither of the parents were wearing seatbelts, and all three kids were in the car seats.

The mother and her six-year-old daughter were pronounced dead at the hospital. The father and his other two kids were taken to the hospital for their injuries, but they are expected to survive.

Deputies believe that speed was a contributing factor to the major crash.
