Washington and Colorado serial rape cases

Between 2008 and 2011, a series of rapes in the suburbs around Seattle and Denver were perpetrated by Marc Patrick O'Leary,[1] an Army veteran who had previously been stationed near Tacoma.[2] Police did not believe the first victim, an 18-year-old woman known as Marie, who reported being raped at her home in Lynnwood, Washington.[3] Detectives' bullying and hounding of her, according to a later report,[1] led Marie to recant her statement, allowing her to be charged with making a false report of rape.[1][3] O'Leary went on to rape five more women in a similar manner, one in Washington and four in Colorado.[1]

O'Leary was arrested in Lakewood, Colorado in February 2011,[4] following 40 days of investigation by a team of detectives collaborating across several departments. The investigators used similarities in the attacker's methods, along with photos found on O'Leary's computer, to link O'Leary to the five rapes in both states.[1] He pleaded guilty to multiple counts of rape and was sentenced to the maximum 327½ years in prison in Colorado[1][3] and a total of 68½ years in Washington.[1][5] O'Leary is currently imprisoned in the Sterling Correctional Facility.[6][7][8]

Between 2008 and 2012, Lynnwood police labeled 21 percent of rape cases as "unfounded", five times the national average for similarly sized municipalities.[1] An outside review of Marie's case by the Snohomish County Sheriff’s Office found that she had been "coerced into admitting that she lied", and that the police had ignored strong evidence of the crime to focus on "minor inconsistencies" in her account.[1] As a result, Lynnwood police have since adopted new training methods for sexual assault investigations,[9] and must have "definitive proof" of lying before questioning a rape report.[3] Despite the critical review, no Lynnwood police officers were professionally disciplined.[1]

T. Christian Miller of ProPublica and Ken Armstrong of The Marshall Project were awarded the Pulitzer Prize for Explanatory Reporting[10] for their "examination and exposé of law enforcement's enduring failures" in the rape investigations.[11] Their work, titled "An Unbelievable Story of Rape", was used as the basis for an episode of This American Life, narrated in part by Armstrong,[10][12] and the Netflix series Unbelievable.[13][14]
