FORT COLLINS, Colo. (CBS4)– More than two dozen cyclists supporting the memory of a bicyclist who was struck and killed in a hit and run, believe the sentence isn’t harsh enough for the driver.

Theresa O’Connor admitted to striking and killing bicyclist Ernesto Wiedenbrug near Windsor on Jan. 25 and then driving away.

A judge sentenced O’Connor, 29, to four years probation for leaving the scene of a crash and one year in jail that can be served as work release.

“Basically it says it’s okay to hit a cyclist and leave them there for dead,” said cyclist Dan Porter.

Wiedenbrug was a beloved scientist who had been out for a ride along the Frontage Road in Windsor. He was born in Argentina and lived in Fort Collins where he was working as an engineer.

O’Connor apologized in court. Her attorney blamed the crash on a medical condition that causes her to feel dizzy.

Friends and family want to know, if she felt dizzy, why didn’t O’Connor stop driving?

“I think the fact that she has to live with what she did is far more harsh than what any court could do,” said Porter.
