In 2001, a man who preyed on heroin addicts and prostitutes pleaded guilty to the 1999 murders of three women whose bodies were found in Forest Park near Northwest Saltzman Road, though forensic analysis showed the murders took place elsewhere and the bodies were brought to Forest Park.[45] In 2003, jurors convicted another man of the 1996 murder of his ex-girlfriend on a Forest Park trail.[46] Less serious crimes have included assault (rarely), car break-ins and petty theft (frequently at trail heads), rare arsons,[47] rare indecent exposure,[48] and marijuana cultivation. Multnomah County Sheriff's deputies in 2007 seized 114 mature marijuana plants found growing in the park on a hillside near Portland's Linnton neighborhood. Deputies had seized another small grow operation in the park in 2005.[49] More common has been illegal camping by homeless transients and others.[50] An illegal bicycling trail, about 1 mile (1.6 km) long, was discovered in a remote part of the park in February 2010.[51] In 2014, hikers found a booby trap meant to fire a shotgun shell across a path leading to the park.
