Intense coverage of the case by the media lent a kind of celebrity status to Berkowitz, and some observers noted that he seemed to enjoy it. In response, the New York State legislature enacted new legal statutes, known popularly as "Son of Sam laws", designed to keep criminals from profiting financially from the publicity created by their crimes. Despite various amendments and legal challenges, the statutes have remained law in New York, and similar laws have been enacted in several other states.
Berkowitz has been incarcerated since his arrest and is serving six consecutive life sentences. During the mid-1990s, he amended his confession to claim that he had been a member of a violent Satanic cult that orchestrated the incidents as ritual murder. He remains the only person ever charged with the shootings. Although some law enforcement authorities have questioned whether Berkowitz's claims are credible, a new investigation of the murders began in 1996, but was suspended indefinitely after inconclusive findings.
