Franklin County Sheriff’s investigators said a 56-year-old Wellsville man died in an accidental shooting last weekend at his home.

Sheriff’s officials had said earlier they were investigating the death of Sean Thomson as a homicide, but that was out of caution because Thomson was home alone at the time of the shooting. Officers were called about 1 p.m. Saturday to his home in the 200 block of Downey Lane in Wellsville. He later died at Olathe Medical Center.

Master Deputy Jerrod Fredricks, a sheriff’s spokesman, said Tuesday morning that investigators believe Thomson was handling the gun when it accidentally fired.

According to his obituary, Thomson worked for 20 years at Liberty Hall in downtown Lawrence.
