Accused killer Garry Handlen was denied bail on Tuesday in B.C. Supreme Court in Vancouver.
Handlen's bail hearing took place last month, and the judge's decison was reserved until this week.
Handlen's next court date has been set for Nov. 4.
The 67-year-old was charged in December with two counts of first-degree murder in the deaths of Kathryn-Mary Herbert, 11, of Matsqui (which later amalgamated with Abbotsford) and Monica Jack, 12, of Merritt.
Kathryn-Mary was last seen in the area of Townline and Marshall roads in Abbotsford on Sept. 24, 1975, and her remains were discovered on Nov. 17 of that year near Harris Road in an undeveloped area of Matsqui First Nations.
Her skull was fractured and her jaw was broken. The autopsy was not able to confirm whether she had been sexually assaulted.
Monica vanished on May 6, 1978 while riding her bike along Highway 5A near the Nicola Ranch in Merritt, B.C. Her remains were found on nearby Swakum Mountain in June 1995.
A date for Handlen's trial has not yet been set.
