On Dec. 2, 2006, Steve Cox was interviewing witnesses at a party in White Center about a car crash when recently released felon and gang member Raymond Porter opened fire, killing Cox before being gunned down himself. Cox’s death forced law enforcement to take a serious look at how they handle gang-related violence, with money and personnel being targeted to combat the issue.But while Cox’s death might result in better police work and interagency cooperation in unincorporated King County, Maria Cox and her son Bronson will never get their husband and father back. Maria believes missing paperwork in Porter’s case file, an escape conviction following a prior arrest that was missed when deciding to release him in Aug. 2006, and lax oversight from Department of Corrections personnel responsible for ensuring that he complied with the conditions of his release, all led to the death of her husband. SWeekly’s Rick Anderson takes a hard look at the state prison’s revolving doors and the impact on cop-targeted violence here.On May 30, Maria Cox filed suit against the state Department of Corrections in King County Superior Court alleging that the agency: “completely failed in its responsibilities in relation to the incarceration and community supervision over Porter. The DOC could have prevented to [sic] death of a highly respected law enforcement officer by adhering the minimal standards.”Last December, Cox filed a $22 million claim against the DOC with the state, according to one of her attorneys, Lincoln Beauregard. The May 30 suit formally puts that claim into the court system.
