Dutch police attempt to solve sex worker murder case with hologram

Betty Szabó, a 19-year-old sex worker, was brutally murdered with over 70 stab wounds behind the window where she advertised herself in the city's red light district.

The perpetrator remains at large.

Anne Dreijer-Heemskerk, a member of the cold case department at the Amsterdam Police, said the hologram was created in the "hope people will remember the case again when they see this."

Dreijer-Heemskerk explained that previous police efforts to find the perpetrator were unsuccessful due to a lack of cooperation from witnesses.

"There are certainly several people who know who committed that crime," she added.

Szabó moved from Hungary to The Netherlands when she was 18 and gave birth to a son just three months before she was killed.

Police are offering a reward of €30,000 for information that leads to her killer.
