Murder in the Alps - S1 E1

2. Episode 2

The second episode sees Saad Al-Hilli's brother Zaid arrested on suspicion of conspiracy to murder, and follows leads that take investigators to Switzerland, Iraq and the USA. Detectives hunt for a motorcyclist with a distinctive helmet spotted near the crime scene, the FBI help to uncover a secret marriage, journalists dig into connections with the Iraqi regime, and police find a Swiss bank account containing almost a million euros.

3. Episode 3

The conclusion of the crime documentary asks why so much attention was focused on prime suspect Zaid Al-Hilli, who was eventually released without charge. Former senior investigating police officer Mark Preston turns the case on its head with a surprising new theory, and other investigators examine whether the killer could still be found, almost a decade after the shootings.
