2-year-old Taj Ayesh, of Lakeland, Florida followed his mother, 29-year-old Stephanie Nealy, when she walked out of her house to get something out of her boyfriend's truck.
Nealy told police that she moved a loaded, unlocked pistol that was inside the truck as she searched for a card. She said she was facing away from the truck when she heard a gunshot and saw her son fall to the ground.
Nealy and her boyfriend rushed Taj to the hospital where he underwent surgery. Taj did not survive.
Police are investigating the incident.
