Dozens of kids die in hot cars each year. Some advocates say better safety technology should be required.

Three years ago, police investigated Tyler Cestia for negligent homicide after he left his 2-and-a-half-year-old son, Thomas, in his truck at work on a hot summer day. 

"In my mind, I remember thinking, 'well, I don't remember walking in the sitter's house to drop Thomas off; I don't remember that,'" said Cestia. "I just said to myself, 'it can't be. There's no way.'"

Cestia said a confluence of circumstances created the perfect storm that June morning. He wasn't originally supposed to drop off Thomas, and the toddler sat in his brother's car seat behind the driver — out of sight. Cestia said he was also recovering from COVID, which gave him brain fog, and his mind was preoccupied with an audit at work. Six hours into his workday, he realized he never dropped off his son that morning.
