A 2-year-old boy was found dead inside his family's SUV hours after a man fatally shot his dad at a Houston gas station, and then stole the vehicle, police said.
Officials have not yet determined a cause of death for the toddler, but they believe it might have been heat exhaustion, Houston Police Executive Assistant Chief Larry Satterwhite said.
Authorities believe the suspect abandoned the SUV with the child locked inside and with the engine turned off as the temperature reached 35C in Houston.
A 38-year-old man was arrested and faces charges of murder and tampering with evidence.
