IOWA COLD CASE UNIT Case Number: 6500401 
On March 9, 1965, Myrtle Zelda Cumpston was shot and killed in the display area of the
C. & K. Aqualand Incorporated, located near Adel, Iowa. The Police are still seeking further information about this murder. If you can help them contact: http://www.dps.state.ia.us/DCI/coldcaseunit/victims/Cumpston_Myrtle.shtml
I found this newspaper item about a woman with the same name who died on the same day. Adel and Coalville are just an hour away from each other. Does anyone know if these were the same woman?
