David Ramon Toschi (/ˈtɒski/ TOSS-kee; July 11, 1931 – January 6, 2018) was an American law enforcement officer widely known for his efforts in the San Francisco Police Department as an inspector in the Zodiac Killer case.

Immediately upon graduation, he joined the US Army, and became a member of the 24th Infantry Division, holding the Pusan Perimeter during the Korean War, honorably discharged in 1952.

[4] He is best known for his role as a chief investigator in the Zodiac Killer case, which he and his partner, Inspector Bill Armstrong, began to work on after the murder of taxi driver Paul Stine.

Toschi was well known for his style of dress, including bow-ties, 'loud' plaid suits, bounteous curls, and exaggerated trench-coat at a time when investigating officers strove to look subdued "like G-men".

George Lucas included a subtle tribute in the 1977 film Star Wars, having Luke Skywalker "going into Tosche Station to pick up some power converters".
