Gary Ridgway was employed by Kenworth.
  Kenworth marked several firsts in truck production; the company introduced a raised-roof sleeper cab, and the first heavy-duty truck with an aerodynamically optimized body design
 Ridgway's victims were not women of any specific race or ethnicity, rather, they were all financially poor, younger women and girls between the ages of 14 and 26 (except for 3) whom he found in vulnerable circumstances, often working as prostitutes or having run away from home
