CHARLOTTE - A father is charged with child abuse for allegedly leaving five children in a car unattended.

Police say it happened Sunday afternoon on East Trade Street. The children are expected to be okay, according to police.

“We’re talking about minutes,” says Lester Oliva with MEDIC. “Even with mild temperatures around 70 degrees, temperatures inside your vehicles can turn life-threatening."

Police say the 39-year-old man left five children unattended in a car for 20 to 30 minutes ranging in age from 9 to 2 years old. Police did not immediately have information about the exact circumstances, including whether the vehicle was in the sun or parked in a garage.

However, medical experts say it serves as an important reminder as temperatures heat up this week.

“We want to make sure 911 is called immediately if you see a child in a vehicle that’s locked,” says Oliva.

Unfortunately, it’s too late for the dozens of children killed each year in the U.S. in hot cars, according to data from San Jose State University. According to the data, at least six children have died already this year.
