A family of six, including four children between the ages of 11 months and 4 years, were found dead in the back of an SUV parked in the garage of a San Antonio home, authorities there said Thursday night.
San Antonio Police Chief William McManus said the smell of gas was so strong when officers arrived that it "kind of blew everybody back out the door".
He said police had gone to the house for a welfare check requested by the husband's employer, who had been unable to reach him.
Police at one point suspected the house was potentially rigged with explosives but found none, McManus said.
