A baby died Sunday after being left inside a hot vehicle in a Belcamp neighborhood, according to the Harford County Sheriff’s Office.

The 6-month-old girl was found unresponsive in the 300 block of Hampton Hall Court, according to a police news release. First responders tried to save her life, “but sadly the child succumbed to her injuries,” the news release stated.

Police were called at 9:47 p.m., and believe the baby was in the car for multiple hours, according to a sheriff’s office spokesperson.

The National Weather Service said temperatures reached a high of 89 degrees Sunday in the Baltimore area. The sheriff’s office noted that a car’s interior temperature can increase by 20 degrees in just 10 minutes “on a warm day.”

Heatstroke begins when the core body temperature reaches about 104 degrees; death occurs at a core body temperature of 107 or above, according to the National Highway Traffic Safety Administration.

As of July 2, nine children had died after being left unattended in vehicles in California, Florida, Louisiana, Maryland, New Mexico, New Jersey and North Carolina, according to Kids and Car Safety, which collects data on hot car deaths. Five died in June.

Last year, 39 children in the U.S. died after being left in hot cars.

No other details were available on the Belcamp death, and no charges have been filed, but the Sheriff’s Office said an investigation continues.
