Torres and her 14-year-old son, Christopher Nuno, were both killed instantly. Investigators say the driver of the Tahoe could face several charges.
"They could be charged any numerous offenses, manslaughter, negligent homicide; it just depends on our reconstruction of our crash," Harris County Sheriff's Office Sgt. Susan Potter said.
Emergency crews airlifted the six-year-old girl to the hospital in critical condition.Investigators say alcohol was not a factor. The driver and passenger of the Tahoe had only minor injuries.
Deputies say they're reconstructing the crash, and will decide whether charges will be filed after their investigation.
