TAMPA — Shawn Lee Burton, 31, has asked a judge to sentence him for leaving the scene of a crash that killed a University of South Florida cancer researcher in 2010 rather than face trial on Tuesday, the State Attorney's Office announced Friday.

Authorities say Burton was driving a 1998 Ford Explorer when he hit 30-year-old bicyclist Kayoko Ishizuka near University Square Drive and Bruce B. Downs Boulevard.

Sheriff's detectives found almost 100 pieces of debris, including paint chips and parts of a broken headlight, at the scene.

Ishizuka had lights on her bike, wore a helmet and rode in the bike lane, investigators said.

Burton had been arrested for driving while intoxicated in California in 2006, prosecutors here said after his arrest.

A jury trial for Burton had been scheduled for Tuesday. Now, he will be sentenced by Hillsborough Circuit Judge Scott Stephens on Oct. 19.
