SUNDAY PM UPDATE:

A man arrested in Carson City Saturday is believed to be the person responsible for four killings in Reno and Gardnerville.

19-year-old Wilber Ernesti Martinez-Guzman is in custody in the Carson City jail on an immigration charge and at least one of stolen property possession. He is also on an immigration hold, and Carson City Sheriff Ken Furlong says while the suspect has apparently been in the Carson City area at least a year, he is in the United States illegally.

Washoe County Sheriff Darin Balaam says there is enough evidence to charge him for all four murders. District Attorneys in Washoe and Douglas counties will look to have him charged with murder in the coming days.

The suspect was arrested after being identified as a person of interest by investigators.

UPDATE:

Washoe County Sheriff's spokesman Bob Harmon tells KOLO 8 News Now that a man is in custody in connection with the investigation into two murders in south Reno.

Harmon says the man was taken into custody Saturday, January 19, 2019 in Carson City. Carson City Sheriff Ken Furlong says the man was arrested on an immigration charge after being rammed by deputies on Carson Street in the Carson Mall parking lot.

Furlong says that person is the only person in custody so far in investigations taking place Saturday on Carson Street and other parts of town, including Woodside Drive. Harmon says the person is not a suspect at this point in the murders, but is likely involved in some way with the investigation. Furlong is not giving specifics yet on the purpose of the overall investigation in Carson City.

No name has been released; more information is expected sometime Sunday. Stay with KOLO for updates.

EARLIER INFORMATION:

The Washoe County Medical Examiner’s Office has released the names of a couple killed in south Reno. 81-year-old Gerald David, a former Reno Rodeo President, and his wife, 80-year-old Sharon David, were found dead in their home January 16, 2019. Both had been shot to death.

January 18, acting on tips, Washoe County Sheriff’s Office Search and Rescue crews searched the southern part of the 580 corridor in Washoe Valley on the chance there might be evidence connected to the killings. Detectives have not revealed whether they found anything connected to the case, but they were looking for things that had been stolen from the home.

WCSO has set up a tip line for the public to call in information. That number is 775-321-4911. You can also call Secret Witness at 775-322-4900 or go to

. Refer to case WC19-306. $5,000 in reward money is being offered for information leading to arrest and conviction. People who give tips to Secret Witness can remain anonymous.

Deputies were called to the Davids’ home near Zolezzi Lane, on La Guardia Lane east of Valley Springs Road the afternoon of the 16th. Sheriff's spokesman Bob Harmon says a neighbor had noticed something didn't seem to look right on the property, and called someone familiar with the family. That person looked around and determined there was reason to call deputies, who found the bodies inside the home.

Neighbors on La Guardia east of Valley Springs are allowed to leave their homes and go back home during the investigation, but they will be escorted by Sheriff's deputies in and out.

The Sheriff's Office says because of similarities between the Reno deaths and

, Washoe County is sharing information with the Douglas County Sheriff's Office. No specifics on those similarities have been released, other than that all the victims are older than 50 and had been shot. Other area agencies, including Reno and Sparks Police and the Carson City Sheriff's Office, as well as the FBI, are also on hand to provide assistance as necessary.

Regarding the causes of death being gunshot wounds, “We have established one more similarity between the La Guardia Lane investigation and the Douglas County homicides; however we are still unable to confirm an absolute connection,” Washoe County Sheriff Darin Balaam says. “Our thoughts and prayers go out to the families of the victims. As these cases develop, law enforcement will continue with our regional collaborative effort aimed at increasing the safety of the public while we work toward bringing those responsible for these crimes to justice.”

All agencies are working together to add patrols as necessary.

The sheriff’s office gives these tips:

keep doors and windows secure

use outdoor lighting if available

don’t open doors for strangers

keep cellphones handy and charged

report suspicious activity to law enforcement
