A Louisiana sheriff's deputy's twin toddlers died over the weekend of heat exhaustion after they were found in a pickup truck outside of their house, according to authorities, NBC News reported.
Bossier City police found the 3-year-old twins — a boy and a girl — in the pickup around 3 p.m. Saturday, according to a statement from the department.
Neighbors called police after the kids' "mother, who was home at the time, had contacted them saying she was looking for the children," the statement said.
The toddlers were pronounced dead at a hospital.
No arrests have been made, but Mark Natalie, a public information officer for the Bossier City Police Department, said Child Protective Services was monitoring the twins' 8-year-old brother.
