His crimes are driven less by theft or conventional assault than by a starved, fantasy-bound longing to possess a woman's love. The case shows how a predator can be a lonely, damaged person and still be dangerous, and how the victims' sense of safety at home collapses even where there is no conventional injury.
The offender's acts are read as a warped attempt to meet a real human need for closeness, which he cannot satisfy through ordinary relationships.
