OCALA, Fla. (AP) - Authorities say a 20-year-old woman shot her infant son and then turned the gun on herself.
    
The Marion County Sheriff's Office reports that 6-month-old Jonah Mendoza was pronounced dead Friday afternoon. His mother, Melanie Reyes, was in critical condition at an area hospital.
    
The Ocala Star-Banner (http://bit.ly/134bYtU) reports that a relative of the mother saw a Facebook posting concerning the woman and a suicide. The relative called authorities, and deputies went to the home of the young woman's parents, which is where the young woman and her baby lived.
    
Deputies arrived about 11:15 a.m. to find the woman and baby in a back bedroom. No one else was home.
    
A handgun was recovered. Investigators were processing the shooting scene.
