REDDING, Calif. -

Redding Police have identified the suspect in an early-morning homicide in West Redding as the nephew of one of the victims.

Officers arrested Cody William Nash, 30, at the home on the 4100 block of Boston Avenue Friday morning, following a 911 call from within the home around 5:30 am. That call was disconnected, and a second 911 call came from a neighbor's home moments later.

When officers arrived, they found Robert Watson, 68, in front of his neighbor's home, suffering from multiple lacerations to his upper body. He was unable to speak with officers and was taken immediately to the hospital. Watson is a former principal at Grant Elementary School in West Redding.

Officers then went to the Watson's home, where the first 911 call came from, and found Candace Watson, 66, dead inside the garage. She had severe lacerations across her entire upper body.

Cody William Nash of Oregon was taken into custody and treated for lacerations to both of his hands at Shasta Regional Medical Center. Nash has been identified as the nephew of Candace Watson.

Redding Police say, during their initial investigation, Nash confessed to the murder of his aunt and the attempted murder of her husband. He is being booked into Shasta County Jail on charges of murder, attempted murder and assault with a deadly weapon.

At last check, Robert Watson was in ICU at Mercy Medical Center with life-threatening injuries.

KRCR News Channel 7's Shay Arthur was the first reporter to arrive after it happened Friday morning. Witnesses tell her they awoke to helicopters flying over their neighborhood around the time of the attack.

Detectives went to several homes, asking neighbors if they knew the couple who owned the home. Detectives told neighbors they did not need to be concerned for their own safety.

Police have closed off Boston Avenue to through traffic and have surrounded the home with crime scene tape. The Coroner's van arrived late Friday afternoon, along with a private cleanup company.

Investigators tell us they expect to be at the home most of the day.
