(WXIN) – An Indiana couple on their way to Arizona never arrived, initiating a search that ended with the husband dead and his wife hospitalized.

On March 27, Ronnie and Beverly Barker set off from a California campground in their RV, traveling across the Nevada desert to see friends in Tucson. Seven hours later, their trail went cold.

They essentially vanished without a trace, with the only clue to their location a ping from an isolated stretch of road. Their RV, car and a host of electronics vanished with them.

Beverly Barker was planning on celebrating her birthday on April 9, and the couple was expected in Tucson on March 29.

Instead, friends and family became concerned once that date came and went.

When was the last time anyone heard from them?

According to the couple’s daughters, the Barkers left Albany, Oregon, around 9:30 a.m. on March 26 after visiting their grandchildren. They headed south on their way to Arizona.

Beverly Barker called a friend around noon that day. As far as the family knows, no one spoke to the couple after that. Since March 28, every phone call made to them has gone straight to voicemail.

Lynn Bledsoe, their daughter, said they wouldn’t have gone so long without returning calls unless something went wrong.

“If they saw I had called, they would have called me back,” she said.

The couple departed the Mt. Shasta KOA Campground in California at noon on March 27. Just before 4 p.m., they stopped in Stagecoach, Nevada, to get fuel. That was their last known purchase.

The last known sighting of the Barkers was a grainy image of their RV on a desert highway in Luning, Nevada. It was taken around 6:05 p.m. on Sunday, March 27.

The final known ping from their cellphone followed just over an hour later, at 7:16 p.m.

Why didn’t a Silver Alert come sooner?

Eight days after their disappearance, a Silver Alert was issued Monday night in Nevada. The delay frustrated family members, who believed there was too much red tape involved in activating the alert.

Jennifer Whaley, another daughter, said local authorities hesitated to issue a Silver Alert because her parents weren’t Nevada residents. Authorities eventually made an exception.

“The reason they weren’t going to give a Silver Alert is that they aren’t residents of Nevada. That, to me, is insane. What does that have to do with anything? They’re missing in your state. So … it’s frustrating,” Jennifer said.

What did the search effort involve?

Local police searched campgrounds and rest stops in the area. Online sleuths and local witnesses also tried to help. Family members looked at everything from stray photographs of the RV to statements detailing credit card purchases.

The family set up an email account specifically for tips about the missing couple: findronandbev@gmail.com.

The Nevada Civil Air Patrol (CAP) assisted in the search this week, although it was unclear if the group spotted the couple’s RV. A spokesperson for the CAP told KLAS the group assisted with 24 personnel from Reno, Las Vegas and Hawthorne.

The CAP utilized four aircraft in search efforts Tuesday, with two additional aircraft on standby. The total air crew time dedicated to the search was approximately 12 hours, covering open desert, mountainous regions, highways, off-road trails and densely wooded areas.

Where were they found?

While specific information regarding how they were found remains elusive, the couple’s nephew, Travis Peters, told KLAS their RV was located in Silver Peak, a small, unincorporated area in Esmeralda County that’s one of Nevada’s oldest mining communities. Neither Ronnie nor Beverly was with the RV and their car, a Kia Soul, was gone.

Ronnie Barker had died, Peters said. Beverly was alive and airlifted to a Reno hospital. Details about Ronnie’s death were not immediately available.

Mineral County Undersheriff Bill Ferguson told The Associated Press that the Barkers were found with their car late Tuesday afternoon. Rescue personnel from Mineral County had located them.

According to Ferguson, searchers found the couple and their car in the forested mountains about 2 miles from the RV.

“It was just one bad decision after another,” he said. “I’m not sure what took them off course. They got the motor home stuck and then unfortunately, they got the car stuck.”

Ferguson said Beverly Barker melted snow for water and stayed mostly in the car. Temperatures dipped into the 30s overnight.
