A lengthy investigation into his horrific crimes concluded that the US police officer who killed his British wife during a murderous rampage was “addicted to sex, drugs and pornography”.
Joshua Burin shot four members of his family including his wife Kelly and mother-in-law Mary King – both of whom came from Northampton – at their Utah home during a terrible accident in January.
Burin had previously drugged, raped and photographed his wife, according to a lengthy and disturbing report from the Spanish Fork Police Department.
The six-month investigation into Burin’s killing spree ended on Monday, and the 154-page report was obtained
Deseret News under the US Freedom of Information Act equivalent.
It states that the 34-year-old killer shot Kelly, 32, Mary, 55, Joshua “Jaden” Buren, 7, and Haley Buren, five, upstairs before shooting himself. .
According to Deseret News, the report says that Burin was sexually assaulted as a child, addicted to drugs and pornography and an intense hatred for his biological mother.
His father killed himself when Burin was five, and the police report states that one of the men she saw next sexually assaulted her son.
Burin had been seeing a therapist since last fall to deal with his failed marriage.
The therapist told the interrogators that the killer drugged his wife until she lost consciousness, raped her, and filmed the ordeal.
Police were told this happened four or five times over a two-year period, although no videos were found during the investigation.
The therapist described Burin as “a three-year-old boy stuck in the body of a big man.”
The report stated: “He was subjected to physical, sexual and emotional abuse as a child, and continues to resent his mother for not being protected from abuse.
Josh had writings indicating that he suffered from inappropriate sexual activity when he was a minor and into adulthood.
“They also state that Josh has a history of drug abuse. The literature appears to support the claim that he drugged and raped Kelly.”
Burin wrote a diary of ideas as part of his treatment, and police found a number of his notebooks after the tragedy.
In one of them, dated December 2013, he wrote: “I have a sex addiction,” “I regularly imagine people I see” and “I imagine being sedated and having sex with Kelly and other women regularly.”
The couple were both bodybuilders, and the report says that Kelly ‘s friends have claimed that she was involved with another man in the gym at the time of the murder.
This man reportedly told the police that he and my agent had exchanged 13,000 text messages in the two days prior to her death.
The investigation found the night before and the morning before the murder that the couple were arguing via text message.
According to the report, Kelly wrote a text message, “You drugged me (expletive) and raped me,” followed by four more texts with just the word “rape.”
She wrote: “I hate my life because of you.” “You killed a part of me.”
But the report alleges that Kelly told the therapist that she did not report the rape cases because she did not want to spoil his law enforcement career. Burin worked for the Utah County Sheriff’s Office.
The report concludes, “Ward began to go out of drugging Josh and rape Kelly, and perhaps he felt that he was about to be reported, which could lead to his job loss and imprisonment.”
Toxicology reports found no trace of alcohol or drugs in Burin or his victims.
Mary King’s sister, Janet Malpass, told the BBC earlier this year that the victims were “really loved” and that their families had been destroyed.
She said, “We are a close-knit family even though we all lived far from them.
“They were all really likable and we will carry this with us all the time.”
