Piers Morgan sits across from convicted murderer Mark Riebe and can barely
disguise his contempt.

After a long interview, the Good Morning Britain host has failed to drag the truth from a man who’s thought to be among America’s worst serial killers, yet the detective who caught him isn’t surprised.

Riebe is serving a life sentence for killing Donna Callahan in 1989, but almost certainly murdered many more women, and the twisted fantasist has tormented the families of his victims for decades by refusing to come clean.

As a piece of TV, this is a chilling glimpse of a wicked and deluded man, with the only satisfaction coming in the final moments when Piers tells him as much.
