With his crimes gaining a rising level of attention, Carver changes his "modus operandi" and begins targeting sex workers while posing as a police officer; he is dubbed the "Water Street Butcher." The police investigating the murders are led to officer James Foley; because Foley has a history of visiting sex workers, is mentioned in eyewitness statements, has no alibi and has matching sperm samples, he is convicted and sentenced to death in 1996. Foley continues to plead his innocence and refuses to make any plea deals. He is executed by lethal injection on September 9, 2001. Days later, his former partner finds a map in his mailbox with the location of another body. The real killer had presumably taken Foley's sperm from a fertility clinic and framed him. Foley is exonerated of the murders on September 12; but because of the proximity to the September 11 attacks, this goes unrecognized by the public.
