Authorities charged a Mississippi mother with second-degree murder nearly a week after her 10-month-old son died in a hot car parked outside her Jackson County home.

According to ABC News, police said Kash Barhonovich was left inside the car for an uncertain amount of time Thursday—when temperatures reached 90 degrees. The Jackson County Sheriff’s Office said the 10-month-old’s autopsy indicated his manner of death was consistent with hyperthermia.

Authorities have since charged Elizabeth Marie Barhonovich, 28, in connection with her son’s death. The Mississippi Clarion Ledger reported that she has other children.

Kash was the 13th child to die this year of a hot-car related death, according to NoHeatStroke.org. Two other children passed away after Kash, raising the death rate to 15 children who have died in hot cars this year.

The SunHerald reported that the Mississippi mom’s bond was set at $50,000.
