he has targeted them for death. by having that really good current understanding of his life history, we were able to prove that he was lying. take a seat. we were able to get a dna sample from him, and that was an exact match from the offender profile that we'd found that the scene of wendy, and a match to what we now knew from the forensic link to caroline. at that point, we thought, here, we've done it. we now knew david fuller was the offender. but then we found something else. he's identified the victims. in 1989, david fuller secured a job at the kent and sussex hospital. that friday evening, we were just sort of tidying everything up, ready for him to go to court the following morning. and we get the camera. he was an electrician by trade and he was a maintenance man.
