The Amsterdam police are making an innovative attempt to solve the 2009 murder of 19-year-old Hungarian sex worker Bernadette ‘Betty’ Szabó. A hologram resembling Betty will engage passersby in the Wallen district, asking for tips. Despite a thorough investigation after Betty’s brutal stabbing, the case turned cold. The police believe public attention could reveal new information and have increased the reward to €30,000. They are hopeful that someone may now be willing to speak up about this tragic incident that cut short Betty’s life and left a young child in foster care.
