David will star as Dennis in Des

According to Laura Foreman's Serial Killers, Dennis feigned surprise when he was investigated after neighbours had complained of plumbing problems, in which human bones were discovered. According to the true-crime book, after being confronted he had said: "It's a long story; it goes back a long time. I'll tell you everything. I want to get it off my chest. Not here — at the police station." When he was asked if anyone else lived at his flat, he added: "Fifteen or sixteen, since 1978."
