It’s difficult to see what the similarities are between the HFS rapes and Cannan’s known crimes, imo.
The HFS rapist was described in various attacks as between 30 and 45 years old, and between 5ft7 and 5ft10. He was well spoken with brown hair, and during one rape threatened to harm the victim's small children.
He wore gloves and on at least one occasion a beige anorak. He tied one of his victims to her bed. He ransacked properties and stole cash.
