In a unique effort to revive public interest in an unsolved murder, Amsterdam police have introduced a hologram of Bernadette Chambo, a young sex worker who was murdered in 2009. The lifelike hologram, positioned in the city’s red-light district, depicts Chambo reaching out for help. Authorities are offering a reward of €30,000 for information leading to her killer, as they aim to encourage witnesses to come forward and finally resolve this long-standing case.
