It happened on August 16 around 3:38 p.m. in the parking lot of the Lindenwold PATCO station.
Authorities say they found an unresponsive 22-month-old girl inside a minivan. Crews tried to resuscitate the child but were unsuccessful.
On Monday, authorities announced charges against the child's legal guardian, 60-year-old Shelton Shambry.
Authorities say Shambry put the child in the vehicle just prior to 6:30 a.m. that morning and forgot that the child was in the vehicle.
The medical examiner ruled the manner of death to be accidental.
Shambry was charged with fourth-degree abuse and neglect. Shambry was released on a summons.
