MARTINEZ -- A Contra Costa jury convicted a Richmond man Tuesday on 21 of 22 felony charges, including first-degree murder, stemming from a 2009 spree of violence.

In keeping with his demeanor through most of his monthlong trial, Jimmie Doss took the verdict with a smile.

Doss, 36, was charged with the shooting death of Clarence Haynes, as well as robbery, false imprisonment by violence, kidnapping for extortion, criminal threats and assault with a deadly weapon related to a string of violent hostage robberies -- all of which occurred during November and December 2009.

Almost overshadowing the voluminous charged offenses against Doss was his erratic behavior during the trial. He had to be removed from the courtroom several times, including on the trial's first day when he soffed at and mocked prosecutor Melissa Smith. Eleven law enforcement officers, including eight bailiffs and three plainclothes officers, were on hand for Tuesday's hearing. Before the jury was allowed in the courtroom, Judge Theresa Canepa warned Doss that he would be removed if there were any outbursts. Four bailiffs formed a semicircle behind Doss during the lengthy reading of the verdicts.

Doss smiled often as if he was amused, shook his head at times and looked pensive at other times. But there were no incidents. He spoke only after the verdicts had been read and the jury had been sent outside the courtroom preparatory to phase two of the trial, in which Smith was to present evidence to the jury that could qualify Doss as a three-strike defendant. When Canepa asked Doss if he wished to sit in on the brief presentation as is his right, he made it clear he did not.

"I'm set for appeal," he said. "This trial has been basically a mockery. As long as I'm set for appeal and set to be released, I don't want to sit through this."

Bailiffs then shackled Doss and led him out of the courtroom.

The jury will begin deliberation on phase two of the trial Wednesday morning. No sentencing date was set.
