Who is Brian Lariva? Nancy Guthrie case brings back shocking memories of Tucson’s terrifying predator

Larriva targeted more than 90 victims and reported more than 30 break-ins, KVOA reported. Some of these homes are located in Nancy’s neighborhoods near Campbell and Skyline.

When police surrounded Lariva’s home, he committed suicide. Like the Lariva case, investigators reportedly have tens of thousands of leads in Nancy’s case.

Robbie Mayer is a former detective with the Pima County Sheriff’s Department who solved the infamous Prime Time Rape case in 1986, Tucson News 4 reports. Most recently, he publicized the Guthrie case.

“We ended up getting over 4,000 leads,” Mayer recalled of Prime Time Rapist. “One of the detectives has Lariva’s name as a clue, but he hasn’t found it yet because he has so many clues ahead of him.”

He said of Nancy’s case, “I believe the suspect’s name is among those 50,000. The question is whether they recognize it when they see it. A case like this is like being in a rocky field and what you’re looking for is under a rock. You just have to keep turning.”

Mayer called Nancy’s case “unique.”

“Most of the time we try to look for patterns. But in this case we can’t,” he said. “These people were prepared, no hair or DNA left. Look at what the person was wearing. They had their phones turned off.”

He added that this was a “high-level investigation” and said he believed the FBI would eventually solve the case.

Nanos also pushed back against suggestions that Guthrie’s case has become a “cold case.” He said the matter only became a cold case after the lab told them they couldn’t identify the blood evidence.
