Patrolman Timothy J. Ruopp, 31, was killed on September 14, 1984, while on duty in Grape Street Park in San Diego. Ruopp and Patrolman Kimberly Tonahill had stopped a vehicle carrying two underage females and two males. Ruopp was issuing a citation to one male for contributing to the delinquency of minors while Tonahill questioned the other male. That suspect produced a concealed handgun as Tonahill began a search and shot her in the side. The suspect then shot Ruopp in the leg and fatally in the head; Ruopp died at the scene.

The suspect, identified as Joselito Cinco, fled after the shootings and was later apprehended following a brief exchange of gunfire with another officer. Ruopp had served two and a half years with the San Diego Police Department, was a U.S. Navy veteran and an ordained minister, and left a wife and four children. If anyone has information about that day or remembers the officers, please share what you know.
