A 56-year-old Burley man has been charged with four counts of first-degree murder following an alleged deadly shooting spree in two southern Idaho counties on Tuesday.

Seven different law enforcement agencies in Cassia and Minidoka counties connected Benjamin Roy Naylor to the murders of a couple in Burley, a separate murder of a woman inside her Rupert home and the fourth murder of a man found dead in an SUV parked behind a closed cafe in Heyburn, according to police and court records the Idaho State Journal recently obtained.

Doorbell camera footage depicting Naylor and his vehicle appears to have played a pivotal role in the investigation.

“This arrest represents the collaborative effort of multiple law enforcement agencies working together to ensure public safety,” Cassia County Prosecuting Attorney McCord Larsen said in a Wednesday news release from Susan C. Ryan of the Missouri-based Vera Causa Group public relations firm. “We are grateful for the swift response and professional work of all officers involved.”

In addition to the four murder charges Naylor faces as a result of the quadruple homicide investigation, he also faces an enhancement for using a deadly weapon during the commission of a felony crime.

“Our offices are committed to working together to seek justice for the victims and their families,” Minidoka County Prosecuting Attorney Lance Stevenson said in the Wednesday release. “This partnership ensures that we can provide the resources and expertise necessary to handle a case of this magnitude.”

Naylor’s family on Thursday issued a statement on social media, apologizing to the victims’ families for his crimes.

“We find it necessary to say something out of respect for the victims involved and their families, as well as the community we have been a part of and loved,” Naylor’s family wrote on Facebook. “Our hearts and thoughts will forever be with every life touched by this terrible loss.”

His family said that Naylor has struggled with severe mental illness for most of his life, adding that “if he were in his right mind, he would be horrified by his actions.”

The investigation into Naylor — which involved Idaho State Police, the Rupert and Heyburn police departments and sheriff’s deputies in Cassia, Lincoln, Minidoka, and Twin Falls counties — began around 3:30 p.m. Tuesday when a police officer responded to a home in Rupert for “an unattended death that occurred under suspicious circumstances,” court records show.

Officers found a woman, whose identity has not been released, in the northwest bedroom of the home deceased from “at least one gunshot wound to the head,” according to a probable cause affidavit filed in support of the criminal charges against Naylor.

Officers reviewed the home’s doorbell camera footage, of which one video showed a man with “a darker mustache and light beard, wearing a black full-brimmed hat, a camouflage print jacket, a dark colored T-shirt with a multi-colored logo, black shorts, white socks and light colored tennis shoes” approach the front door of the residence and knock around 1:34 p.m., the affidavit states.

Another video showed the man “wearing a yellow glove on his left hand and his right hand was holding a firearm tucked under his jacket on the left side of his body,” according to the affidavit.

The doorbell camera captures the same man leaving the residence around 1:51 p.m., according to the affidavit.

Screenshots of the man were distributed to area law enforcement, the affidavit states, adding that a Minidoka County sheriff’s deputy identified the man as Naylor.

Around 6:21 p.m., Cassia County sheriff’s deputies responded to a home in Burley for a report that two people had been shot, police said in a subsequent probable cause affidavit filed in support of the criminal charges against Naylor.

A 66-year-old man was found dead in the living room in front of a couch from a gunshot wound to the head and a 62-year-old woman was found dead from a gunshot wound to the head in a closet near the back of the house, the affidavit states.

An online fundraiser started by the couple’s surviving daughter and comments on the Cassia County Sheriff’s Office Facebook page identified the Burley shooting victims as Kelly and Donna Jenks.

“On July 8, our community was shaken by the unimaginable,” The GoFundMe states. “Kelly and Donna Jenks were tragically murdered in their home in Burley, Idaho. This devastating loss has left their family, friends, and neighbors reeling in grief and disbelief.”

The fundraiser, accessible by visiting gofund.me/6c786ba7, says Kelly and Donna Jenks were “loving parents, devoted grandparents and cherished members of their community.”

“They leave behind their only daughter Jerica Harper, her husband Alex and their sweet baby girl Adalee — their pride and joy,” the GoFundMe states. “Kelly and Donna were overjoyed to step into the role of grandparents and baby Adalee was truly the light of their lives.”

The online fundraiser says Jerica and Alex shared an incredibly close bond with Kelly and Donna, living just blocks away.

“The sudden and violent loss of both parents is absolutely heartbreaking,” the fundraiser states. “In the midst of profound grief, they are now faced with the heavy burden of planning a double funeral, navigating complex arrangements and coping with an ongoing murder investigation.”

Court records show that investigators obtained and reviewed video of the Jenks’ residence that showed a gold 2013 Toyota Tundra parked against the curb across the street where a man, later identified as Naylor, exited the truck and entered the home, the affidavit states.

Investigators also connected Naylor to the alleged murder of a man found dead inside of a 2010 Ford Expedition that was parked behind the closed Connor’s Cafe in Heyburn, police said. The man’s identity has not been released.

Around 10 p.m. on Tuesday, Lincoln County sheriff’s deputies located the gold Tundra near the intersection of S. Greenwood and State Highway 24, according to the affidavit.

“The deputy followed the Tundra northbound on State Highway 75 while he waited for additional officers,” police said. “The deputy initiated a traffic stop northbound on State Highway 75 near milepost 90.”

Naylor was identified as the driver, police said. He was wearing a light colored woodland camouflage jacket, a black Steve Miller Band T-Shirt and black shorts, said police, adding that he was found to be in possession of a 1911-style handgun.

Naylor was subsequently arrested and booked inside the Mini-Cassia Jail in Burley.

He made his initial appearance in court on Wednesday, during which he was ordered to be held in jail without bond.

Both prosecutors emphasized the importance of allowing the legal process to proceed without interference from speculation or misinformation.

“We ask the public to refrain from spreading unverified information about this case,” Larsen said in the Wednesday release. “Such speculation can harm the investigation and potentially impact the defendant’s right to a fair trial.”

Naylor is due back in court for preliminary hearings on July 18 and July 23. Various motions to seal and preserve court records are set for hearings on July 15 and 17.
