The speedboat seducer who made a fatal error

Jack Shepherd had a polished seduction routine. He would take women out for expensive meals and thrilling rides on his speedboat. But one night his fixation on trying to impress went horribly wrong when he killed his date, Charlotte Brown. Shepherd met Charlotte - or Charli, as she was known - for the first time on a December night in 2015. Before that, they'd got to know each other online through the dating website OkCupid.
