Dutch police hope to solve the murder of a sex worker using a hologram

“A completely different life awaits them in Amsterdam. “Betty starts working as a sex worker in the red light district,” Amsterdam police said in a statement. “She has a striking appearance, with her friendly smile and a large dragon tattoo on her stomach and chest.”

Shortly after finding work, Szabó became pregnant. She continued to work throughout the pregnancy and her son was placed in foster care immediately after his birth.

Szabó died on February 20, 2009, just three months after the birth of her son. Her body was found with multiple stab wounds in a pool of blood in a prostitute's study on Oudezijds Achterburgwal in Amsterdam's red light district.

“She had been brutally murdered. Alarmed by the unusual silence in her room, her sex workers found her that night,” investigators said. “The case is still not solved.”

Now investigators have created a life-size hologram of Szabó, which they hope will lead to a lead in the investigation. The hologram sits on a stool in a window and tries to ask people who see it for help.

Benjamin van Gogh, the coordinator of the wanted and missing persons team in Amsterdam, told The Guardian that officers were cautious before creating the hologram and launching the high-profile campaign to find her killer.

“Before we decided to use a hologram for the campaign, we discussed with various parties inside and outside the police whether we should go ahead with it and how we should set it up,” he said. Her family is said to have approved the project.

Another investigator, Anne Dreijer-Heemskerk, determined that Szabó was killed at one of the busiest intersections in the Netherlands.

“It's really almost impossible that there wouldn't be people who saw or heard something unusual at this point. Or heard someone talking about the case that didn’t even have to take place in Amsterdam,” Dreijer-Heemskerk said. “After all, the red light district attracts visitors from all over the world.”
