HUBER HEIGHTS -- The grandmother of a NFL star was shot inside her Huber Heights home Wednesday night. Authorities are saying the shooting appears to be accidental after 70-year-old Mae Worthy's husband accidentally fired a handgun he was handling in the back room of their Rolling Glen home. Huber Heights Lieutenant Matt Dulaney said the evidence is in line with the husband's story, "it (bullet) went through the bedroom wall, down into the opposite end of the house and it happened to strike her in the back of the head while she was sitting on the couch." Dulaney said the husband has been cooperative with authorities. We found out in 2007, there was another accidental shooting between Mae's husband, James, and her 14-year-old granddaughter's father. A gun accidentally went off in the home that night -- hitting the teen. It's unclear who fired the weapon in that incident. Neighbors tell us the couple have been together for decades, "they're very nice. Very nice," said one neighbor. Police want to remind everyone of firearms safety, "if I have my firearm out, I'm not pointing it in any direction, other then the ground," said Dulaney. We're told the case has been handed over to the prosecutor's office for possible negligence with firearms. Mae Worthy is in critical condition -- and her husband is not in custody at this time.
