Westerfield would have taken police to the site where her body was located, in exchange for a sentence of life without parole. Both the prosecution and the defense declined to comment on these reports. Many people, including Fox News commentator Bill O'Reilly, expressed outrage at the revelation, claiming that Westerfield's attorneys misled the jury by proposing an "unknown kidnapper scenario" even though their client said he knew the location of the body; however, legal specialists pointed out that defense attorneys are obligated to mount a vigorous defense regardless of their own opinion of the client's guilt or innocence. In the months following the end of the trial, audio tapes of Westerfield being interviewed were released to the media. During his first interview, he is heard to ask an officer to "leave your gun here for a few minutes" in a seeming suggestion that he would like to commit suicide. In one police interview he tells investigators that he does not feel emotionally stable. In one interview he is told that he failed a polygraph test; Westerfield says he wants a retest and that he was not involved in Danielle's disappearance. In late 2003, San Diego police received a letter from an outside party confessing to Danielle's murder. The author claimed to be James Selby, a man accused of various sex-related crimes in five states, including in the San Diego area. Both police and Dusek read the letter, and deemed it not credible; however, Dusek forwarded the letter to the office of Westerfield's attorney, Steven Feldman, who declined to comment. Selby, who also claimed responsibility for the slaying of JonBenét Ramsey, committed suicide while awaiting sentencing in Arizona on November 22, 2004. An episode of Animal Witness, an animal-based forensic series on the US TV network Animal Planet, was based on the belief that hairs consistent with Danielle's dog, which were found in Westerfield's laundry, in his RV, and on his comforter at the dry-cleaners, first got onto her pajamas when she cuddled with the dog, and then were carried on the pajamas to his house and RV in accordance with Locard's exchange principle. Legacy An overpass on Interstate 8 in El Cajon has been named the Danielle van Dam Memorial Overpass. It is near the place where her body was found. The years after the murder have led to increased levels of crime awareness in San Diego's neighborhoods as well
