POMONA, California (AP) - A Southern California woman has been sentenced to death for smothering her two young sons with a pillow and killing her husband with a sword. Prosecutors say 32-year-old Manling Tsang Williams killed her family so she could be with a lover who wanted her to divorce. City News Service reports Williams was sentenced on Thursday on three counts of first-degree murder for the August 2007 killings at her home in Rowland Heights. Authorities say Williams smothered her sleeping boys, ages 3 and 7, then scanned her lover's MySpace page on her computer and went out with friends before returning home and hacking her sleeping husband to death. Neal Williams, 27, was cut more than 90 times.
