Going unmentioned, the Head Box used on Colleen went missing some time after the trial. It is of great interest to law enforcement because if it were found intact advances in forensics could now prove if it was also used on Marliz.
Scenes of the Hooker house were shot at the actual Hooker residence. Several members of the crew described having eerie feelings of intense cold in the basement despite shooting in 100 degree temperatures. It is still owned by the family that got it following Cameron's arrest who have left it much the way it was. The family is very accommodating to renewed investigations on the Spannhake case as new developments in forensics occur.
Scenes at Spannhake's apartment were not filmed at the real apartment complex but another complex down the street that was built at the same time with the same design by the same builders. However, at the end Marliz's sister is looking at the real apartments.
