Alarm für Cobra 11 - Semir Gerkhan's partners

Hint

Answer

The first partner ever, worked at the Autobahnpolizei before Semir alongside Ingo Fischer.

The second partner, who was tough and considered to be rather aggressive. Presumably killed in Mallorca, he returned as an antagonist 14 years later.

The third partner, who was Semir's good friend. Had a 2 years pause, but returned. Killed by gangsters while protecting a young Asian girl.

The fourth partner, considered to be a rookie, yet was very brave and loyal. Disappeared without a single word from the show and was replaced by the third partner.

The fifth partner, who used to work as an undercover agent. Suffered from PTSD, he was shady and not particulary sharing. Killed in action while saving the life of his lover.

The sixth partner, who had a rough start but managed to get on Semir's good side, even despite his rebelious nature. Retired after a few years and became a full-time musician.

The seventh partner that has experience with prison. Rough and professional, we worked with Semir for a few years and left the police force to look for his mother in Brazil.

The eighth partner, who was young and charming. Semir saved his life when he was a little boy. Their friendly/mentoring relationship ended by him leaving police force and taking a journey on a boat with his dad.

The ninth and a last Semir's partner. Even thought they had a bad start, they managed to get along fairly well. It's a first and only female partner.
