Chanin Starbuck was killed by her ex-husband, Clay Starbuck. A Spokane County jury convicted him of aggravated first-degree murder on June 4, 2013, and a judge sentenced him to life in prison without any possibility of release. The 42-year-old mother of five was found dead in her Deer Park, Washington, home in December 2011. The case against Clay was built on DNA, digital forensics, and a crime scene prosecutors argued he had staged to throw investigators toward one of her online dating partners.
What Was Found in the Deer Park Home
Chanin’s body was discovered on December 3, 2011, in the master bedroom. She was positioned on the bed in a sexually degrading manner, and sex toys had been placed around the room in what police described as being arranged “like they were on display.” Investigators believed the staging was deliberate. An autopsy showed she had been strangled and tased, with bruises and internal injuries consistent with a prolonged attack. There were no signs of forced entry.
The coroner also testified that a sexual device had been used on the body after death, which became the basis for a separate charge of sexually violating human remains.
Why Investigators Focused on the Ex-Husband
Clay and Chanin had finalized a contentious divorce in July 2011. Their post-divorce relationship was marked by bitter disputes over money and the children. In October 2011, a court ordered Clay to pay $9,600 in back child support and attorney fees. Prosecutors argued that financial resentment and jealousy over Chanin’s dating life drove him to kill her.
Their theory of the day itself: on December 1, 2011, Clay lured Chanin out of her home by faking a car breakdown, entered the house while she was gone, and attacked her when she returned. Police also noted his reaction when they told him she was dead. He showed no visible distress and instead seemed eager to talk about her online dating activities. He was arrested during a traffic stop in Deer Park and held on $1 million bond on charges of aggravated first-degree murder and first-degree burglary.1The Spokesman-Review.

The DNA Evidence
DNA was the most contested part of the trial. The Washington State Patrol Crime Lab used Y-STR testing, which reads DNA passed through the male line from father to son. Y-STR profiles are identical among all males in the same paternal lineage, so the test cannot tell a father apart from his sons on genetics alone. Clay’s Y-STR profile matched DNA recovered from Chanin’s right hand fingernails and her neck. To make that match mean Clay specifically, the prosecution had to place his sons elsewhere. Investigators confirmed that Drew, Austin, and Blake were at work or school when the murder occurred, leaving Clay as the only male in the Starbuck line without an alibi.
The DNA picture was not entirely clean. Male DNA on Chanin’s phone keypad excluded Clay. A vaginal swab contained sperm from a donor who was also not Clay. In total, DNA from three unidentified males turned up on the limited number of items tested. The defense argued that significant physical evidence went untested altogether: nineteen hair strands collected from Chanin’s body, a vaginal wash from the autopsy, the sexual device found on her body, and the mattress pad and bedding. A thorough investigation, the defense said, would have tested everything and might have pointed to a different killer.
The 911 Call and the Texts
On the morning of December 1, 2011, Chanin’s cell phone placed a 34-second call to 911. The recording captured sounds of a struggle but no intelligible words. Prosecutors argued the call was made during the attack itself.
Chanin’s phone came back online around noon. Someone then used it to send text messages to her ex-boyfriends and her children. When her daughter texted asking who would pick her up from school, the reply read: “Dad. I have a headache.” Detective Lyle Johnston testified that whoever sent those messages had intimate knowledge of the children’s school schedules and was working to keep them away from the house. The prosecution’s argument was that Clay sent the texts to create the illusion Chanin was still alive, buying time before her body was found two days later.
The Trial and Verdict
The trial opened in spring 2013 in Spokane County Superior Court. The charging document alleged aggravated first-degree murder with five aggravating factors, including that Clay acted with deliberate cruelty and that Chanin was especially vulnerable, alone in her home and unable to defend herself.2FindLaw. State v. Starbuck – Washington Court of Appeals The prosecution described a man driven by greed, anger, obsession, and jealousy, and argued the staged scene was meant to frame one of Chanin’s dating partners for a sexually motivated attack.
The defense pushed back on two fronts. It argued that the DNA was inconclusive because the Y-STR match could not single out Clay from other males in his paternal line, and because three unidentified men’s DNA was found at the scene. It also argued the investigation had been narrow from the start. The trial court had granted the prosecution’s motion to exclude “other suspects” evidence, so the defense could not present alternative theories about who else might have killed Chanin. The court also excluded evidence about her sexual relationships with men she had been dating.
After deliberating over parts of two days, the jury found Clay Starbuck guilty of aggravated first-degree murder and sexually violating human remains.3The Spokesman-Review. Starbuck Guilty of Ex-Wife’s Murder
Sentence and Appeal
Under Washington law, a conviction for aggravated first-degree murder carries a mandatory sentence of life imprisonment without any possibility of release or parole. No judge can suspend or defer it, no parole board can reduce it, and the statute bars any furlough or release program.4Washington State Legislature. RCW 10.95.030 – Sentences for Aggravated First Degree Murder Clay Starbuck, 48 at sentencing, received that mandatory term. The court also issued a no-contact order barring him from any communication with his three minor children.
He appealed to the Washington State Court of Appeals on four grounds: exclusion of his “other suspects” evidence, insufficient evidence, admission of the 911 recording, and prosecutorial misconduct during closing argument.2FindLaw. State v. Starbuck – Washington Court of Appeals
The appellate court rejected every argument. On the other-suspects issue, it held that Starbuck failed to establish a “nonspeculative link” between any alternative suspect and the crime, which Washington law requires. The men Chanin had dated had no demonstrated connection to the murder, and one alternative suspect’s phone records placed him far from Deer Park on the day of the killing. On sufficiency, the court found the circumstantial case strong: the DNA match, Clay’s financial and emotional motives, the texts showing intimate knowledge of the children’s schedules, and the staging of the scene all pointed to him. On the 911 call, the court ruled it was not testimonial hearsay because it captured sounds of a struggle rather than any statement, so its admission did not violate his right to confront witnesses.
The appellate judges unanimously upheld both the murder conviction and the life sentence.5The Spokesman-Review.
