Winchester pass a clue in 1979 killing
The case began as a string of robberies in Austin, Texas, until the 1979 night when a struggling singer-songwriter named Michael Cahill chased down the thief who was stealing his guitar... and got a bullet in the forehead.
What makes the case so unusual is that the killing appeared to be the work of a burglar who targeted photographers who had contributed to an artsy photo calendar called "The Book of Days," whose small circle of contributors included future Pulitzer Prize-winning cartoonist Berkeley Breathed of "Bloom County" fame.
Winchester, widely considered one of the heroes of American folk music, is unconnected to the still-unsolved case other than that pass which was made for a performance at the Austin Opry House and attached to Cahill's guitar at the time of the murder, according to the television program, which originally aired in April.
Cahill was obviously a fan of Winchester, a passionate foe of war who, in the 1960s, popularized the song "Yankee Lady" and fled the Vietnam draft to Canada. He moved to the Charlottesville area last year.
