Question: What crime is Gary Ridgway associated with? 
Context: Green River Killer is a 2005 American crime film by Ulli Lommel starring George Kiseleff, Jaquelyn Aurora (as Jacquelyn Horrell), Georgina Donovan, Shannon Leade, Naidra Dawn Thomson, and Shawn G. Smith.  It is based upon the crimes of serial killer Gary Ridgway. The "Meleager" of Skopas is a lost bronze sculpture of the Greek hero Meleager – host of the Calydonian boar hunt – that is associated in modern times with the fourth century BCE architect and sculptor Skopas of Paros.  The sculpture escaped mention in any classical writer.  It is judged to have been a late work in the sculptor's career, but it is known only through a number of copies that vary in quality and in fidelity to the original, which show it to have been one of the famous sculptures of antiquity: "the popularity of the Meleager during Roman times was certainly great," notes Brunilde Sismondo Ridgway, who reports Andrew F. Stewart's count of 13 statues, 4 torsos, 19 heads (which are similar enough to the Ludovisi Ares to raise confusions) busts and herms, a variant with changed stance and attributes, and 11 versions adapted for a portrait or a deity.  Six or seven of the accepted copies are accompanied by a dog, 12 wear a chlamys, 3, clinching the sculptural type's identification with Meleager, are accompanied by a boar's head trophy, as in the Vatican "Meleager" ("illustration, right").  Ms Ridgeway accounts for the sculpture's popularity in part "by the appeal that hunting figures had for the Romans, through their heroizing connotations." Tammy A. Vincent was an American teenager who was murdered in September 1979.  Her body was not identified until 2007, twenty-eight years after her death.  Despite the fact that her identity was discovered, the case remains unsolved, although a prime suspect has been selected.  It was believed she may have been a victim of the notorious Green River killings, which have an approximate number of 49 victims while she remained a missing person.  Gary Ridgway has since pleaded guilty to most of these killings, plus six additional murders.  However, Vincent's case has not been officially solved. " NCIS" cast member Pauley Perrette collaborated with the popular television show "America's Most Wanted" in 2009 to work on solving the case.
