Cops: Bone Near Garrido House Likely Human

Police say a bone fragment found near Phillip Garrido's Antioch, Calif. house is probably human.

Garrido, a convicted sex offender, and wife Nancy allegedly kept Jaycee Dugard, now 29, captive in tents and sheds in their backyard for 18 years. Garrido also fathered Dugard's girls, 15 and 11, authorities say.

Additional DNA testing is under way, reports "Early Show" national correspondent Hattie Kauffman, even more about Garrido's past is surfacing.

He once wore long hair, and sang in a band and, even back then, his interests were clear, says former band mate Eddie Loebs, who recalls Garrido as a womanizer with an "association with" porn.

Loebs told celebrity Web site Radaronline.com he saw Garrido snort cocaine and mistreat his first wife. "He'd bring over a girl that he met somewhere," Loebs says, "and his wife would go sleep in the next room."

Newly discovered lyrics said to have been written by Garrido show his obsession with young girls, Kauffman observes. One such lyric: "Feelin' good, la la la, stop and took her for a candy bar."

Special Section: Jaycee Lee Dugard

Twenty years later, Dugard was snatched.

Former prosecutor Michael Cardoza says police sources tell him Garrido and Nancy, his second wife, specifically targeted Jaycee. "The day before Jaycee was actually kidnapped," Cardoza said to CBS News, "the Garridos were out looking, I call it child shopping -- they were out actually looking for someone to kidnap. And they went by a group of little girls, one of which was Jaycee Dugard and, as they went by, Philip said to Nanci, 'Ooh, ooh, I want that one. She's cute. Her. Her.' "

The next day, Kauffman says, the Garridos went back and grabbed Jaycee as she stood alone at a bus stop.
