Prosecutors said Hamel with one other person followed Bui as he stopped alongside the curb in front of his friend’s home in Santa Ana.

During a confrontation, prosecutors said Hamel blocked-in Bui’s car and drove over his head after he was knocked to the ground by a co-defendant.

Bui died instantly.

Prosecutors say Hamel withdrew a 2013 guilty plea after requesting to have the evidence in the case further analyzed.

She faces a sentence of life in prison without the possibility of parole during a May 29 hearing.
