CHALLIS, Idaho (AP) — An 86-year-old man has been arrested in connection with a 1980 shooting in central Idaho that left one man dead and another injured.

The Custer County Sheriff’s Office says 86-year-old Walter James Mason was arrested Oct. 10 in Eastland County in central Texas and transported to Idaho on Oct. 13.

According to court records, Mason is charged with first-degree murder and has a preliminary hearing Monday. His court-appointed attorney, Dave Cannon, didn’t return a call to The Associated Press on Tuesday.

Mason is a suspect in the Sept. 20, 1980 killing of 52-year-old rancher Daniel Woolley outside a bar in Clayton, Idaho.

Mason was found in Texas living under the alias Walter James Allison.

Authorities have not released details on what led investigators to Mason.
