Keith Siegel, the hostage who was released from Gaza about two weeks ago, had been working as a pharmaceutical sales representative for the Danish company Lundbeck, which specializes in psychiatry (its most well-known drug is the antidepressant Cipralex), until he was abducted.
According to a report tby the medical news website Doctors Only, following Siegel's kidnapping, Lundbeck Global hired a specialist in locating missing persons, a former operative of the British intelligence agency MI6, who arrived in Tel Aviv and operated in Gaza with a mandate to negotiate with Siegel's captors. However, his efforts were unsuccessful, and after about three months of activity, the agent's mission was terminated,

In an effort to obtain information on Siegel's condition and whereabouts, the international company examined every possible lead, analyzing all available footage across local, Arabic, and international media. However, no breakthrough was found.
"There was very strong backing from the Danish company at the start, extensive efforts were made, and various avenues to assist were explored," said Shani Tzuri, marketing director of Lundbeck Israel, in an interview with Doctors Only. "But at a certain point, alongside the fatigue and weariness of the situation, the entire senior management of the company in Denmark was replaced, and we were left here with our harsh reality."
Tzuri added that at all company gatherings, both in Israel and worldwide, employees made sure to display Siegel's photo along with the number of days he had been missing. They continued to fight for his release while maintaining contact with his family.
