Deputy District Attorney Martha Carrillo with the Sex Crimes Division said Robert Charles Lee, 42, was sentenced by Superior Court Judge Larry P. Fidler. A jury deliberated about 2 ½ days before finding Lee guilty of 36 counts, including nine counts of forcible rape and 13 counts of forcible oral copulation. The verdict was read on March 26.

Carrillo said Lee attacked his victims in their homes and sexually assaulted many of them at knifepoint. The victims ranged in age between 32 to 80 years old, but most were elderly and disabled. One victim was assaulted on two separate occasions. The assaults occurred between 1997 and 2006.

Four of the 10 victims lived in Orange County, Carrillo said. Lee was arrested and charged with the sexual assaults in June 2006 after a DNA sample connected him to assaults in Los Angeles, Gardena, Carson and Brea.
