Pauline and her husband Louie said they had let Paala stay with them after he was kicked out of his parents' house.In weeks, they noticed jewelry was missing and they confronted their guest."He turned white. For a Samoan, he turned a little white," Louie said.Paala's next move took them by surprise. He met them at a pawnshop where he authorized the clerk to show the couple his account, which listed many of their missing items.Louie recounts Paala's words to the clerk, "Yeah, I stole all their stuff. This is all their stuff."As Eyewitness News reported in February, Paala has a history of taking deposits for appearances , failing to show up, then seeking forgiveness."I do apologize for my actions," Paala said to viewers of RadioUnderland last winter.And now Montebello police said Paala has confessed to grand theft.

Montebello police urge all Paala clients to contact their local police departments if they suspect he was stealing valuables as he was engaging young fans.
