Donna Lee Sobb of Sacramento, who won a $50,000 lottery prize, has been fined $153 in Sacramento Municipal Court for a petty theft she committed last January. Sobb, 31, pleaded guilty to the charge and immediatedly paid her fine. The former welfare mother of three was arrested at a Sears store after reportedly placing three children's outfits in a bag and leaving the store without paying for them. She reportedly told the store detective that she stole the outfits for her son's birthday, which was the next day. Sheriff's deputies said the publicity about Sobb being one of the state's first big lottery winners enabled them to find and arrest her.
