The Merced County Sheriff’s Office said in a Facebook post on Friday morning that it had arrested Alberto Salgado, the brother of Jesus Manuel Salgado who is suspected of kidnapping and murdering Aroohi Dheri, Jasleen Kaur, Jasdeep Singh, and Amandeep Singh.

Alberto Salgado, 41, was arrested Thursday night for criminal conspiracy, accessory, and destroying evidence, authorities said.

Suspect Had Worked for Family’s Trucking Business, Had Feud With Them

Murder suspect Jesus Manuel Salgado, 48, had worked for the family’s trucking business and had a longstanding feud with them that culminated in an act of “pure evil,” Merced County Sheriff Verne Warnke said Thursday.

The bodies of Aroohi Dheri; her mother Jasleen Kaur, 27; father Jasdeep Singh, 36; and uncle Amandeep Singh, 39, were found by a farm worker late Wednesday in an almond orchard near Dos Palos.

Investigators were preparing a case against the suspect — a convicted felon who tried to kill himself a day after the kidnappings — and sought a person of interest believed to be his accomplice. Relatives and fellow members of the Punjabi Sikh community, meanwhile, were shocked by the killings.

“Right now, I’ve got hundreds of people in a community that are grieving the loss of two families, and this is worldwide. These families are across different continents,” Warnke told The Associated Press. “We’ve got to show them that we can give them justice.”

Suspect Booked Into Jail

Jesus Salgado was released from the hospital and booked into the county jail Thursday night on suspicion of kidnapping and murder, the sheriff’s office said. It wasn’t clear if he had a lawyer who could speak on his behalf.

Warnke Calls for Death Penalty Trial

Earlier, Warnke called for prosecutors to seek the death penalty. The sheriff called it one of the worst crimes he has seen over his 43 years in law enforcement and pleaded for Salgado’s accomplice to turn himself in.

“There’s some things you’ll take to the grave. This to me was pure evil,” he said in an interview Thursday.

The city of Merced, where the family’s trucking business was located, is holding evening vigils in their memory through Sunday.

At the vigil Thursday evening, hundreds of people held lit candles and formed a circle of around enlarged photos of the victims. Religious leaders of different faiths opened the ceremony with prayers for the family, the Merced Sun-Star reported.

“Tonight was the community coming together and showing the Singh family that ‘we’re here with you and we will be here with you for as long as you need us, and we will remember the names of those we lost,’” family friend Priya Lakireddy told the newspaper.

The Victims

Salgado’s Criminal History

Salgado was previously convicted of first-degree robbery with the use of a firearm in Merced County, attempted false imprisonment and an attempt to prevent or dissuade a victim or witness. Sentenced to 11 years in state prison in that case, he was released in 2015 and discharged from parole three years later, according to the California Department of Corrections and Rehabilitation. He also has a conviction for possession of a controlled substance, the department said.

Relatives of Salgado contacted authorities and told them he had admitted to them his involvement in the kidnapping, Warnke told KFSN-TV on Tuesday. Salgado tried to take his own life before police arrived at a home in Atwater — where an ATM card belonging to one of the victims was used after the kidnapping. Efforts to reach Salgado’s family were unsuccessful Thursday.

The victims were Punjabi Sikhs, a community in central California that has a significant presence in the trucking business with many of them driving trucks, owning trucking companies, or other businesses associated with trucking.

Public records show the family owns Unison Trucking Inc. and relatives said they had opened an office in the last few weeks in a parking lot the Singh brothers also operated. The feud with Salgado dated back a year, the sheriff said, and “got pretty nasty” in text messages or emails. Other details about Salgado’s employment and the nature of the dispute were not immediately available.

Sheriff Believes Family Quickly Killed After Kidnapping

Warnke said he believes the family was killed within an hour of the Monday morning kidnapping, when they were taken at gunpoint from their business.

Surveillance video showed the suspect — later identified as Salgado — leading the Singh brothers, who had their hands zip-tied behind their backs, into the back seat of Amandeep Singh’s pickup truck. He drove the brothers away and returned several minutes later.

The suspect then went back to the trailer that served as the business office and led Jasleen Kaur, who was carrying her baby in her arms, out and into the truck before the suspect drove them away shortly before 9:30 a.m.

Hours later, firefighters on Monday found Amandeep Singh’s truck on fire in the town of Winton, 10 miles (16 kilometers) north of Merced. Police officers went to Amandeep Singh’s home, where a family member tried to reach him and the couple. When they were not able to reach their family members, they called the sheriff’s to report them missing.

They were likely already dead.
