As I have stated on another thread my suspect in this case would be Ralph Leon Jackson who I believe struck in Missouri as the I70 Killer and was capable of controlling multiple victims. Of course it might be difficult to get a definitive answer but LE will have to look into it:
I-70 Killer - Wikipedia
On May 4, 24-year-old Nancy Kitzmiller was killed while working alone at Boot Village, a footwear shop in
St. Charles, Missouri. She opened up the shop at noon and was found dead by customers at 2:30 p.m.

The final confirmed murder occurred on May 7 in
Raytown, Missouri. The victim was 37-year-old Sarah Blessing who was working in her gift shop, Store of Many Colors. The murder occurred during the day, and the owner of the video store next to the Blessing’s shop saw the killer enter the shop, heard a pop, and then saw him leave. He discovered Blessing's body after checking to see what had occurred in the store. A clerk at a nearby grocery store also saw the suspect. He was climbing a hill towards I-70.
