for tourists. With the increased tourist traffic of Expo 86, dealers introduced an influx of high-purity cocaine and heroin. In efforts to clean up other areas of the city, police cracked down on the cocaine market and street prostitution, but these activities resurfaced in the DTES. Within the DTES, police officers gave up on arresting the huge numbers of individual drug users, and chose to focus their efforts on dealers instead. Meanwhile, the provincial government adopted a policy of de-institutionalization of the mentally ill, leading to the mass discharge of Riverview Hospital's patients, with the promise that they would be integrated into the community. Between 1985 and 1999, the number of patient-days of care provided by B.C. psychiatric hospitals declined by nearly 65%. Many of the de-institutionalized mentally ill moved to the DTES, attracted by the accepting culture and low-cost housing, but they floundered without adequate treatment and support and soon became addicted to the neighbourhood's readily available drugs. Between 1980 and 2002, more than 60 women went missing from the DTES, most of them sex workers. A large number of missing women are missing and murdered Indigenous women. Robert Pickton, who had a farm east of the city where he held "raves", was charged with the murders of 26 of these women and convicted on six counts in 2007. He claimed to have murdered 49 women. As of 2009, an estimated 39 women were still missing from the Downtown Eastside. 1990s to present In the 1990s, the situation in the DTES deteriorated further on several fronts. Woodward's, an anchor store in the 100-block of West Hastings street, closed in 1993 with devastating effect on the formerly bustling retail district. Meanwhile, a crisis in housing and homelessness was emerging. Between 1970 and the late 1990s, the supply of low-income housing shrank in both the DTES and in other parts of the city, partly because of conversion of buildings into more expensive condominiums or hotels. In 1993, the federal government stopped funding social housing, and the rate of building social housing in B.C. dropped by two-thirds despite rising demand for it. By 1995, reports had begun to emerge of homeless people sleeping in parks, alleyways, and abandoned buildings. Cuts to the provincial welfare program in 2002 caused further hardship for the poor and homeless. Citywide, the number of homeless people climbed from 630 in 2002 to 1,300 in 2005. Without the
