Samuel Isaacs was charged with first degree assault around 12:30 a.m. on Tuesday.
The teenage boy who was shot was the love interest of Isaacs’ 13 year old granddaughter.
Pat Melton, the Franklin County Sheriff, and a Franklin County Constable, Richard Sandifer, walked along the train tracks with Isaacs Monday from about 7 p.m. until midnight.
Melton said the entire time Isaacs had a gun on himself and was walking along the R.J. Coleman train tracks near Chenault Road, about a mile from where the shooting happened.
"He said I’m not here to hurt you. I’m here to hurt myself," said Melton.
Isaacs was at peace according to Melton, but around midnight was taken into custody by Kentucky State Police Special Task Force.
The task force then handed Isaacs to the sheriff’s office where they questioned him.
"He said his granddaughter had snuck out with the boy," said Melton.
Isaacs’ arrest papers said he was taken to the Franklin County Regional Jail.
His charges could mean between 10-15 years in a detention center.
Kentucky State Police are also handling an investigation. Their spokesperson said they have filed an additional charge of resisting arrest.
