Sheriff's investigators will discuss the results of their investigation into a 4-year-old boy who shot his mother in the back after getting ahold of her loaded gun.

The Putnam County Sheriff's Office is scheduled to address reporters at 2 p.m. Tuesday about its criminal inquiry into the mother, Jamie Gilt. She's apparently a gun lover who made numerous social media postings about gun rights. She's been hospitalized since the March 8 incident.

She was shot while driving after the boy somehow got hold of a loaded gun and fired through the driver's seat.

The 31-year-old mother could face charges of leaving a weapon unsecured and improperly stored, but authorities have said she legally owned the firearm.

Florida's Department of Children and Families also is investigating.
