CARSON CITY, Nev. (KOLO)-- A man suspected of killing four people in south Reno and the Gardnerville Ranchos area sold stolen jewelry belonging to two of them at a Carson City coin store, charges newly-filed in Carson Justice Court Thursday allege. The amended complaint with additional charges was filed January 24, 2019, shortly before his first appearance in Carson City Justice Court, and the day after the original complaint was filed.
Wilber Ernesto Martinez-Guzman, 19, sold an Elks ring belonging to Gerald David for $126 and sold stolen silver rings, toe rings and turquoise ring belonging to Connie Koontz for $33 to Northern Nevada Coin in Carson City, the charges say.
Martinez-Guzman also had a gold ring with channel-set diamonds and red stones and a gold fan ring with clear stones that belonged to Koontz, the complaint says. The complaint says he got $379 for selling unspecified rings that belonged to Koontz to Northern Nevada Coin.
Charges added Thursday include:
12 new counts of possession of a stolen firearm, including rifles, shotguns and one handgun belonging to Gerald and Sharon David.
Two counts possession of stolen property – an Apple watch belonging to Connie Kootnz, plus golf club and tools belonging to another Carson City burglary victim.
Twelve counts of prohibited person in possession of a firearm.
Two misdemeanor counts of possession of stolen property, rings belonging to Connie Koontz.
Three misdemeanor counts of obtaining money under false pretenses for the sale of two rings belonging to Connie Koontz, one belonging to Gerald David.
The complaint relates to events that allegedly happened only in Carson City and does not deal with the deaths in Washoe and Douglas counties.
Koontz was found shot dead at her home in the Gardnerville Ranchos. Authorities believed it happened January 9 or 10, 2019. January 13, 74-year-old Sophia Renken was found shot dead a mile away.
January 16, the bodies of 81-year-old Gerald David, a former Reno Rodeo president, and his wife, 80-year-old Sharon David, were found in their home on La Guardia Lane in south Reno. They had also been shot.
The charges filed Wednesday do not list any items taken from Renken’s home. Investigators say they have a mountain of evidence to dig through.
David’s ring was engraved with the initials JD and the date 12-25-74. Martinez-Guzman allegedly had 16 silver rings, toe rings and turquoise rings that belonged to Koontz.
The complaint has nine charges: three felony counts of burglary for going into the business with the intent to get money under false pretenses; a felony count of possessing David’s Elks ring, which had a value of $650 to $3,500; two misdemeanor counts of possession of stolen property worth less than $650 for Koontz’s jewelry; and three misdemeanor counts of obtaining less than $650 for selling all the jewelry.
He sold the Koontz jewelry January 12 and 14 and he sold David’s ring January 17, the complaint says.
