On the evening of July 31, 1974, 15-year-old Cynthia Cindy Ardina Leslie and her 13-year-old sister Jackie Lynn Leslie left their family’s mobile home in Mesa, Arizona, while their parents were at a church service and never returned. The family had moved to Desert Sands Mobile Home Park from Page so the girls’ father, Jack, could be closer to medical care for terminal cancer. The sisters left a note saying they were going to a babysitting job; investigators later determined that was false and that the girls intended to attend a party and that Cynthia wanted to meet a teenage boy her father had forbidden her to see.

They were last seen walking west on Baseline Road near Power Road, a few blocks from home, in an area then described as semi-rural with cotton fields and orange groves. Reports from partygoers conflicted about whether the sisters arrived. Extensive searches at the time and in later years found no trace of either girl. Foul play is suspected but no concrete evidence has been made public. The Maricopa County Sheriff’s Office keeps the case open and has released age-progressed images; the family has continued to seek answers.

Did anyone in the community remember sightings of the sisters that night or know more about the people who hosted that party?
