A suspect connected to a shootout with police and also killing a man who he and another suspect were allegedly trying to carjack last week in San Jose appeared in court Wednesday.

A shackled 26-year-old Jonathan Dawson Wilbanks shuffled into Santa Clara County Superior court Wednesday afternoon, keeping his head down and rarely changing his somber expression the entire hearing.

Wilbanks was captured and arrested last Friday night after police say he and another man went on an armed robbery crime spree culminated in the two of them shooting and killing 22-year old Rory Parkpettiford during an attempted carjacking outside a convenience store. 

Police say, afterwards, Wilbanks and his partner opened fire on police officers during a chase.

Wilbanks surrendered after a standoff, and the other suspect remained unidentified and on-the-run as of Wednesday.

On Wednesday, Wilbanks was charged with numerous counts including attempted murder on a peace officer as well as first degree murder with special circumstance -- the carjacking.

"That potentially is a 'life without the possibility of parole' or a 'death penalty' charge, so there's not much more you can do to somebody after that," said prosecutor James Leonard. "Given the nature of the case, the defendant will be held without bail."

Wilbanks did not speak in court and afterward, defense attorney Charles Fredrickson had only a short comment when KTVU asked him what he wanted to say on behalf of his client.

San Jose Police said the public has responded after the department's plea this week for more community help, but so far it hasn't helped the investigation."

"No new leads, but they are fielding phone calls,” said San Jose Police Spokesman Albert Morales. “But nothing has panned out as of yet."

Wilbanks was scheduled to return to court on Dec 5 to enter a plea.

There was still a $20,000 reward being offered for information leading to the capture and conviction of his accomplice.
