WEST PALM BEACH, Fla. -- West Palm Beach authorities are investigating how a boy was left in a hot car as his mother did her nails hours before her wedding. The 4-year-old boy later died at a hospital.

The Palm Beach County Medical Examiner says the boy's temperature reached 108 degrees Fahrenheit.

The Palm Beach County Sheriff's Office says that 29-year-old Mirland Baptiste may not have known the boy was in the car. She dropped off other children at a relative's house Saturday before going to the salon.

She was supposed to get married later that day. Instead, the family mourned the death of Gregory Cesar.

Officials say the boy may have been in the car for more than two hours. Temperatures had reached 90 degrees.

Sherline Examor, a friend of the boy's family, told WPBF-TV that Gregory was a "good boy" and that the incident was just a horrible accident.

"He was a regular boy. He's a good little boy. But she's a good person. You know, it was an accident. It could've happened to anyone like that," Examor said.
