Richard Allen Davis

Richard "Rick" Allen Davis is an American pedophilic murderer, abductor, and bank robber. He is most well-known for being responsible for the passing of California's Three Strikes law.

Background
Davis was born on June 2, 1954 to Bob and Evelyn Davis. He was the third of their five children. Both Bob and Evelyn were alcoholics, and according to Davis' attorney, Evelyn was a strict disciplinary (allegedly once burning his hand when she caught Davis smoking). His parents divorced when Davis was eleven. Davis and his siblings stayed with their father, who was sometimes unwilling and incapable of raising them, causing them to have to shuttle between other relatives. Bob also remarried twice, giving Davis two stepmothers (who he loathed). Davis showed signs of being a sociopath at a young age (later being diagnosed with Anti-Social Personality Disorder, or ASPD). He frequently killed stray animals, especially cats who he would burn alive, and dogs he would cut with a knife he carried with him. On October 12, 1973, an 18-year old Marlene Voris was found dead from a gunshot. Seven suicide notes were found at the scene. Some believed Davis had murdered her (as he had been at her house when she had a party). Davis later confessed to a psychologist that her death deeply affected him (even going so far as to claim he heard her voice in his head, telling him she wanted to be raped, robbed, or assaulted).

Early Crimes
Davis began ranking up a highly lengthy criminal record, starting at the age of only twelve. He was arrested then on March 6, 1967 for a burglary. He was arrested later again that month on the 24th for forging a $10 money order. On November 15, 1969, Davis was arrested for another burglary. Bob Davis later turned him and Davis' brother to authorities for "incorrigibility" several times.

Modus Operandi
Since Davis only killed one person, the term M.O. is somewhat misused. When he killed Polly Klaas, he abducted her from a slumber party, strangled her, then buried her in a shallow grave.
