Robert Lee Yates

In July 2015, the Washington Supreme Court once again rejected an effort by Yates to overturn his conviction and death sentence. After the Washington State Supreme Court ruled in 2018 that the death penalty violated the state constitution, Yates's death sentence, as well as that of Washington's other death row inmates, was commuted to life in prison without the possibility of parole.

In 2013 Yates's attorneys filed a habeas corpus petition in federal district court, stating that Yates is mentally ill and, "through no fault of his own ... suffers from a severe paraphilic disorder" that predisposed him to commit murder. The still-pending motion is regarded as a "long shot" by most observers. "I don't think Mr. Yates helps his cause by relying on the fact that he's a necrophiliac," said Pierce County Prosecutor Mark Lindquist.

Yates remains incarcerated at the Washington State Penitentiary. His case was further complicated by Washington Governor Jay Inslee's 2013 declaration that he would not sign death warrants for anyone on death row while he is in office. Inslee cited the high cost of the appeals process, the randomness with which death sentences are sought, and a lack of evidence that the penalty serves as a deterrent to other criminals.

The 2002 death sentence was appealed on grounds that Yates believed his 2000 plea bargain to be "all-encompassing", and that a life sentence for 13 murders and a death sentence for two constituted "disproportionate, freakish, wanton and random" application of the death penalty. The arguments were rejected in 2007 by the Washington Supreme Court. A September 19, 2008 execution date was stayed by Chief Justice Gerry L. Alexander pending additional appeals.

In 2002, Yates was convicted of killing two women in Pierce County and sentenced to death but it was commuted to life without parole after Washington outlawed the death penalty in 2018. He is currently serving life in prison at the Washington State Penitentiary.

In 2001 Yates was charged in Pierce County with the murders of two additional women. The prosecution sought the death penalty for the deaths of Melinda L. Mercer in 1997 and Connie Ellis in 1998, which were thought to be linked to the killings in Spokane County. On September 19, 2002, Yates was convicted of those murders and subsequently sentenced to death by lethal injection on October 3, 2002.

Yates was arrested on April 18, 2000, for the murder of Jennifer Joseph. After his arrest a search warrant was executed on a 1977 white Corvette that he had previously owned. A white Corvette had been identified as the vehicle that one of the victims had last been seen in. Coincidentally, Yates had been pulled over in this vehicle while the Task Force was searching for it, but the field interview report was misread as saying "Camaro" not "Corvette", thus the incident was not realized until after Yates had been arrested.

After searching the Corvette, police discovered blood that they linked to Jennifer Joseph and DNA from Yates that they then tied to 12 other victims. In 2000 he was charged with 13 counts of first-degree murder and one count of attempted first-degree murder in Spokane County Superior Court. As part of a plea bargain in which Yates confessed to the murders to avoid the death penalty, he was sentenced to 408 years in prison.

On August 1, 1998, Yates picked up sex worker Christine Smith, who managed to escape after being shot, assaulted and robbed. On September 19, 1998, Yates was asked to give a DNA sample to Spokane police after being stopped. He refused, stating that it was too extreme of a request for a "family man".

Yates left the Army in April 1996, apparently a year and a half short of being eligible for his full retirement benefits and pension. At this time the military was reducing its numbers so he got his full retirement despite being short of the customary 20 years served.

In October 1977 Yates enlisted in the United States Army, in which he became certified to fly civilian transport airplanes and helicopters. Yates was stationed in various countries outside the continental United States, including Germany and later Somalia and Haiti during the United Nations peacekeeping missions of the 1990s. Yates also served three years in the Army National Guard as a Helicopter Pilot from April 1997 through April 2000. He earned several commendation and service medals during his military career, including the US Army Master Aviator Badge.

The murders Yates committed between 1975 and 1998 in Spokane all involved sex workers who worked along Spokane's East Sprague Avenue. The victims were initially solicited for sex work by Yates, who would have sex with them (often in his 1979 Ford van), sometimes do drugs with them, then kill them and dump their bodies in rural locations. All of his victims died of gunshot wounds to the head. Eight of the murders were committed with a Raven .25-caliber handgun, and one attempted murder was linked to the same model of handgun.

Yates grew up in Oak Harbor, Washington in a middle-class family that attended a local Seventh-day Adventist church. He graduated from Oak Harbor High School in 1970. In 1975, he was hired by the Washington State Department of Corrections to work as a correction officer at the Washington State Penitentiary in Walla Walla.

Robert Lee Yates Jr. (born May 27, 1952) is an American serial killer from Spokane, Washington. From 1975 to 1998, Yates is known to have murdered at least 13 women, all of whom were sex workers working on East Sprague Avenue, in Spokane. Yates also confessed to two murders committed in Walla Walla in 1975 and a 1988 murder committed in Skagit County.
