LOS ANGELES—A serial killer who pleaded guilty last year to a crime spree in Los Angeles and Santa Monica that left five men dead and seven others injured, along with the killings of his aunt and uncle in Texas, has been charged with murdering his cellmate in a Kern County prison, authorities announced on Sept. 18.
Ramon Alberto Escobar is set to be arraigned Sept. 20 in connection with the Feb. 24 strangulation of Juan Villanueva at North Kern State Prison, according to the Kern County District Attorney’s Office.
The murder charge includes the special circumstance allegation of seven prior murder convictions. Mr. Escobar is also accused of committing an assault with malice by an inmate serving a life sentence, according to the Kern County District Attorney’s Office.
Mr. Villanueva—who was sentenced in Los Angeles County to life with the possibility of parole for aggravated sexual assault of a child under 14—was discovered unresponsive in the cell that he occupied with Mr. Escobar, the California Department of Corrections and Rehabilitation said earlier this year.
Mr. Escobar was sentenced in May 2022 to two life prison terms without the possibility of parole plus 124 years to life in prison for the crime spree in Los Angeles County.
During a subsequent video conference in that same downtown Los Angeles courtroom, Mr. Escobar pleaded guilty to the August 2018 killings of his aunt, Dina Escobar, and his uncle, Rogelio Escobar, in Texas, in a plea deal that spared him a potential death sentence in that state. He was also sentenced to life in those two slayings, and will serve his time in a California prison.
The murder charges in Los Angeles County involved a Sept. 10, 2018, attack in Santa Monica on Juan Antonio Ramirez, 51, who died of his injuries in January 2021; the Sept. 16, 2018, killings of Branden Ridout, 24, and Kelvin Williams, 59, in downtown Los Angeles; the Sept. 20, 2018, killing of Steven Cruze, 39, of San Gabriel, under the Santa Monica Pier; and the Sept. 24, 2018, slaying of Jorge Martinez, 63, in Santa Monica.
Mr. Escobar—who had indicated as early as November 2018 that he wanted to settle his case without going to trial—admitted the special circumstance allegations of multiple murders and murdering Mr. Cruze during the course of a robbery, along with pleading guilty to attempted murder involving seven other victims.
“Guilty,” the defendant said over and over again last year as Los Angeles County Superior Court Judge Mark Hanasono asked him how he pled to each of the charges.
During the May 2022 hearing, Suzanne Gonzalez called Mr. Cruze an “amazing father” who coached the baseball and basketball teams of their son, who was 11 when his father was killed.
“We suffered a tragic loss that we may never recover from,” she said during the hearing. “We will do everything to cherish his memory.”
In a statement read in court on her behalf, Mr. Cruze’s mother said she prayed that her son didn’t struggle or suffer and said her son—who would have given Mr. Escobar money if he had been asked—was “murdered for no reason whatsoever.”
“I grieve and suffer daily ... ,” she wrote. “All of us are devastated.”
Authorities said Mr. Escobar drove to California after being questioned by authorities in Texas about the disappearance of his aunt and uncle, who were siblings.
Los Angeles police obtained surveillance videos in downtown Los Angeles that showed Mr. Escobar beating a man with a baseball bat the same day Mr. Ridout and Mr. Williams were killed and then going through his pockets, according to a sentencing memorandum filed by Los Angeles County Deputy District Attorneys Victor Avila and Hilary Williams.
Mr. Escobar was wearing distinctive clothing and had a “very distinct bow-legged walk,” and Los Angeles police publicized video stills showing Mr. Escobar to ask for the public’s help in finding him, according to prosecutors.
Shortly after Mr. Martinez was struck in the head with what appeared to be bolt cutters, a Santa Monica police officer recognized him as the man involved in the downtown Los Angeles killings and detained him, according to the prosecution’s sentencing memo.
Detectives subsequently searched Mr. Escobar’s SUV and seized a wooden baseball bat believed to have been used in the two killings in downtown Los Angeles, and Santa Monica police found a pair of bolt cutters believed to have been used in one of the attacks, authorities said.
Some of the attacks were against people who were homeless, but Los Angeles Police Department Capt. Billy Hayes said in 2018 that the attacks did not appear to be based on any hatred toward homeless people.
“I think it was a crime of opportunity,” he said. “... It appears the motive in most of these cases was robbery.”
Mr. Hayes said Mr. Escobar was homeless himself, having recently arrived in the area from Texas in a 2004 black Honda CRV. He said Mr. Escobar arrived in the Southland on Sept. 5, less than a week before the attacks began.
Authorities said in September 2018 that Mr. Escobar was a person of interest in the disappearances in Houston of his aunt and uncle.
During an October 2018 interview with police, Mr. Escobar said he wanted to talk with them “about the people [he] killed and their locations” and said there were “bodies they can’t find,” such as his aunt and uncle in Houston, whose bodies he said had been dumped in separate trash bins, according to the prosecution’s sentencing memorandum.
“The reasons defendant gave for killing some of the victims in Los Angeles included the following: the victims irritated him, they were disrespectful to law enforcement, or he robbed them because he needed money,” according to the sentencing memorandum.
He was subsequently charged in Texas with killing his aunt and uncle, whose bodies were not able to be recovered from a landfill.
The prosecutors noted in their sentencing memorandum that the settlement would “not only hold defendant accountable for crimes committed against all of the victims in the instant case and keep him in custody for the rest of his life, but it would also avoid having to conduct a trial in which the surviving victims, witnesses, and relatives of victims would have to relive the violent acts committed against them or their loved ones.”
Criminal proceedings were suspended in California after a doubt was declared about his mental competency to stand trial, but proceedings were reinstated in June 2021 after he was determined to be competent.
One of Mr. Escobar’s attorneys in the Texas case, James Stafford, told City News Service after the hearing that his client had been “having some major mental issues” and that he thought “the gods and the demons were telling him to do this.”
Mr. Escobar served five years in prison from 1995 to 2000 in Texas for burglary, and had subsequent arrests in 2017 and earlier in 2018 on suspicion of assault and criminal trespassing, Mr. Hayes said earlier.
