Deaths from heat exhaustion are not uncommon, yet they don’t regularly make national news. That changes when negligent parents leave their kids in their cars during the summer months. And that’s just what has happened again. This time, though, it looks purposeful. A Texas mother stands accused of leaving her two kids in her car to die. On purpose.

Amanda Hawkins, 19, is from Kerr County, Texas. The teenage mother is alleged to have left her children Brynn Hawkins, just one year old, and Addyson Overgard-Eddy, who was two, in her car overnight.

The next day, Hawkins brought both of the unconscious children to a hospital, but both died.

“This is by far the most horrific case of child endangerment that I have seen in the 37 years that I have been in law enforcement,” Kerr County Sheriff Hierholzer said.

The Kerr County Police believe Hawkins left the children in her car for 9 hours while she went and partied with friends. They say that the children were seen crying in the car, and that Hawkins was told that they were crying, but that she ignored them.

One of her friends, a 16-year-old, even slept for a while in the car, with the children, but did nothing to aid the children.

Hawkins, who works at a local Walmart, is married. Her husband was not present during the event.

It wasn’t until Wednesday at noon that Hawkins removed the children from the car. Both were unconscious. Even then, Hawkins didn’t seek medical attention. She was afraid of the consequences. When a friend convinced her to take them to the hospital, Hawkins concocted a story about the children suffering an allergic reaction after smelling flowers in the park.

The staff at the hospital, though, saw through that. Hawkins has been charged with two counts of abandoning or endangering a child. Those charges will be upgraded now that both have died.

Hawkins, who is fond of supporting her chin with one hand while taking selfies, will have a hard time defending the charges against her, and will likely face even more harsh sentencing because of her selfish and slow response.
