Judith Mackay, 7, and Susan Debra Mackay, 5, disappeared on the morning of Aug. 26, 1970, from a school bus stop 660 feet from their home in the Townsville suburb of Aitkenvale less than 10 minutes after leaving home. A search for the missing girls was mounted after they failed to return home after school and continued until the girls bodies were found on Friday in the dry bed of Antill Creek, 16 mi south-west of Townsville. Susan was found first and a trail of footprints from her body led searchers 230 ft to where Judith's body lay. They were found stabbed and strangled.
