REDDING, Calif. -

It took jurors just a few hours to convict Cody Nash on all charges, including first degree murder of his Aunt Candace Watson.

Emotion overwhelmed the many family members and loved ones of Candace inside the Shasta County courtroom Thursday afternoon as the guilty verdicts were read aloud.

Those closest to Candace wore pink and purple, her favorite colors, and Hawaiian attire – their way of keeping her spirit with them in the courtroom.

Nash never once looked back at his family or his uncle Bob Watson, who was severely slashed at the hands of Nash. Bob is now confined to a wheelchair because of the violent June 2012 knife attack.

"It is a tragedy, and it's still unbelievable. It's still horrendous and unbelievable,” explained Dawn Lawrence, the daughter of Candace and Bob Watson.

“It's sad on all aspects, with Cody, it's sad, sad, sad. For our family, I don't know what to say," Lawrence said through tears.

Despite Nash's defense attorney's attempt at convincing the jury his client's mental illness played a role in the killing, the jury also unanimously decided Nash had been lying in wait - before violently slitting his aunt's throat.

He was also found guilty of attempted premeditated murder and assault with a deadly weapon, for the attack on his uncle Bob.

Shasta County Deputy District Attorney Curtis Woods said he believes the jury did the right thing, by finding Nash guilty of all charges against him.

"It was a swift verdict. And Mr. Nash's punishment will also be swift and harsh as he deserves for what he did to this family here in Redding. He shattered the lives of Bob and Candace Watson's family and their children’s family,” said Woods outside the courtroom.

Nash is facing life without the possibility of parole. His sentencing is scheduled for April 21.
