A Baton Rouge man was working on his handgun Saturday night when it accidentally discharged, killing a 13-year-old boy who was baby-sitting his kids.

The incident began when 25-year-old Adonis Forbes was out celebrating an anniversary with his wife. The couple decided to check on their kids at about 9 p.m. before heading out again, said Cpl. L’Jean McKneely, a Baton Rouge police spokesman.

While they were at their house at 2014 Tennessee St., Forbes decided to check on his gun and found it was malfunctioning — and while trying to fix it, the gun fired, McKneely said.

The bullet struck the baby-sitter, Murrain Hawkins, of 3405 Myrtlelawn St., in the abdomen.

When police arrived, they found Hawkins lying on the ground with a bullet wound and Forbes trying to administer aid, McKneely said. The teen was taken to a hospital where he was pronounced dead.

Forbes was questioned and ultimately booked into Parish Prison on a count of negligent homicide. His bail was set at $10,000.

It was unclear whether Hawkins and Forbes are related, McKneely said.
