REDDING, Calif. -

A Shasta County jury found Cody Nash guilty of first-degree murder and assault with a deadly weapon on Thursday afternoon.

Nash was charged with slitting his aunt Candace Watson’s throat, killing her, then severely attacking his uncle Bob Watson inside their west Redding home in the early morning hours of June 8, 2012.

Bob is now wheelchair-bound because of the knife attack.

The jury was handed the case late Wednesday afternoon after hearing closing arguments for much of the day.

They began deliberating Thursday morning and reached a verdict just after 2 p.m.

In those closing arguments, Shasta County Deputy District Attorney Curtis Woods told jurors he firmly believed Cody Nash committed the "cold, calculated murder of his aunt.”

Woods went on to point out this crime was "all thought out, the defendant coming up behind her, grabbing her hair and slitting her throat.”

Nash's defense attorney, Michael Horan, spoke about a statement he previously made during opening arguments, saying he and his client “are not disputing what happened.” But that “nothing about this case is black and white.”

Horan also stated that this trial is "about Cody Nash's mind - chemically, emotionally and how it's affecting his decision making."

The very last piece of the case played for the jury was the 911 call Candace made after her throat had been slit. She never spoke on the tape - but everyone in the courtroom could hear her last breaths being taken.
