Rusty Day (born Russell Edward Davidson; December 29, 1945 – June 3, 1982) was an American rock singer,[1] best known for his work with Cactus, the Amboy Dukes, and Steve Gaines.

Cactus was conceived in late 1969 as a supergroup of the Vanilla Fudge rhythm section, bassist Tim Bogert and drummer Carmine Appice, plus guitarist Jeff Beck and singer Rod Stewart.

In 1976, Day re-incarnated Cactus by placing an ad in Rolling Stone which stated that he needed exceptionally good guitar, bass, and drums.

The murder officially remains unsolved, although the Seminole County Sheriff's Office believe the victims may have known the perpetrator, and that the killings may have been drug-related.

[2] In 2011 and 2015, it was asserted that Ron Sanders, guitarist and bandmate in Uncle Acid & the Permanent Damage Band, was the perpetrator of the shooting.
