A bicyclist accused of striking and killing a pedestrian in San Francisco's Castro District nearly a year ago pleaded not guilty Thursday to felony vehicular manslaughter.

Chris Bucchere, 36, did not speak during a brief court allowing his attorney Ted Cassman to enter his not guilty plea.

He was ordered to return to court for a pretrial hearing on April 23rd.

Prosecutors allege that Bucchere ran multiple red lights and a stop sign before striking Sutchi Hui, 71, at Castro and Market streets shortly after 8 a.m. on March 29, 2012.

Assistant District Attorney Omid Talai has told the court Bucchere showed a lack of concern for the victim in an online post he made on a cycling forum the day of the collision.

In that post, Bucchere said he wanted to dedicate the story to his "late helmet" that was destroyed in the crash. The post prompted criticism from other forum members and was later taken off the site.

"He is not dedicating this story to the man that he killed," Talai said.

Cassman has countered that Bucchere "was concerned about Mr. Hui because he is a good man" and visited the hospital to check on him before he died days after the collision.
