A new donor is enabling the Islamic Center of San Antonio to add $80,000 to its reward in the search for four-year-old Lina Khil. The center raised its reward on Sunday to $200,000. The Crime Stoppers reward is still 50-thousand-dollars, bringing the total rewards to $250,000. Lina disappeared in December from a playground at the Villa Del Cabo Apartments on Fredericksburg Road. Her family observed the girl's fourth birthday at the apartments on Sunday.
