Woman, 8-year-old girl die of carbon monoxide poisoning at home in Houston

A woman and an 8-year-old girl are dead due to carbon monoxide poisoning after a car was left running in a garage to help generate heat, Houston police say.

KTRK reports that HPD officers and the Houston Fire Department were called to do a welfare check at a condominium in the 8300 block of La Roche near Jackwood in southwest Houston.

When officials arrived, they found two adults and two children affected by carbon monoxide poisoning.

The woman and the 8-year-old girl did not survive

KTRK reports that upon entering the condo, police found the woman dead in her vehicle. The girl was found dead in the condo, which is attached to the garage that housed the running car.

An adult male and a 7-year-old boy were transported to the hospital for carbon monoxide poisoning.

"Initial indications are that (a) car was running in the attached garage to create heat as the power is out," police wrote in a tweet. "Cars, grills and generators should not be used in or near a building."
