Maddie's accident occurred shortly before 3 p.m. on Sunday, and was witnessed by both 25-year-old Jamie Lynn and her husband, Jamie, who were approximately 100 yards away from Maddie at the time. According to a police report on the incident obtained by ET, Maddie was steering her ATV to avoid running over a drainage ditch near a pond on the family property in Louisiana when she "overcorrected," and caused the vehicle to enter the pond.

"The ATV and child were instantly submerged in the water right before their eyes," a statement by Tangipahoa Parish Sheriff Daniel Edwards read. "The child was trapped and secured by the seatbelt and the ATV's safety netting. Within two minutes, Acadian Ambulance Services arrived and assisted in freeing the child from the cold waters."
