The Tarrant County Medical Examiner's Office has not yet released the names of the woman and child who died after their car crashed into a pond Thursday night, but according to family members the driver's name was Christina Williams, 36, and her daughter was Tisiphone Rose, 22-months, both of Mansfield.
Richard Williams of Irving told NBC 5 he is the estranged husband of Williams, from whom he has been separated for two years.
Richard Williams said Christina had likely just picked up her child from child care prior to the crash.
"Usually she'll call me after she picks up Tisiphone and let me talk to her while she's driving. Yesterday she didn't," Richard Williams said. "And I thought that was kind of strange, 'cause I hadn't heard from her all night."
According to Williams, Christina was often distracted when she drove and he is concerned that may explain why she reportedly ran a stop sign prior to Thursday night's accident.
"I knew she was gonna get in another wreck one of these days but not like this," Williams said. "She had quite a few little minor accidents, 'cause she doesn't always pay attention to what she's doing."
Police said the vehicle was heading east on Collett Little Road when it ran a stop sign and collided with a car heading southbound on the Loop 820 service road. The force of the crash sent the car that ran the stop sign through a fence and into a pond at the Amelia Park Apartments in the 6100 block of Southeast Loop 820, police said.
The woman driving the car called 911 as her vehicle was sinking. She told the Forest Hill police 911 operator that she couldn't open the doors to her car.
Forest Hill police have released a recording of the 911 call, but NBC 5 has chosen not to air or post it because it is too disturbing.
Police have not made an official ruling on the crash.
