Duration: 1 x 47'

This jaw dropping documentary looks into what turned a sweet schoolgirl into one of Britain’s worst ever serial killers. How did the daughter of loving parents become a ruthless murderer who tortured and stabbed lovers and strangers without motive?

Over two weeks in 2013, 30-year-old Dennehy murdered three men and attempted to kill two others. At trial, she showed no remorse for her victims, and became one of only three British women ever to be sentenced to spend the rest of her life behind bars.

Five years on from Dennehy’s conviction, Susanna Reid speaks to the lead detective, the father of her two children, family members of victims, a man who was present when two of the attacks took place, school friends and experts who reveal how an intelligent and privileged young girl transformed into a dangerous, bloodthirsty psychopath.
