Kim Kardashian West wants to be a forensic investigator because she is ''obsessed with murders''.

The 34-year-old reality star - who has 16-month-old daughter North with her rapper husband Kanye West - is so intrigued by killers she has asked to do internships as a forensic investigator because she is convinced she would be able to help solve murder cases.

When asked about what she might have done if she'd taken a different path in life, she told London's Time Out magazine: ''Maybe a make-up artist. I just love make-up. But more than that, I would love to be a forensic investigator.

''I've literally asked attorneys to intern on a case, a big murder trial. I know I can help solve it.''

The 'Keeping up with the Kardashians' star admitted that while she is fascinated by criminals, she feels very sad for the victims.

She said: ''I'm obsessed with murders. I don't really understand why someone would kill someone. I just feel so sad for people.''

Kim's comments come after her late father, Robert Kardashian, acted as the primary defence lawyer for American footballer O.J. Simpson - the brunette's godfather - during his murder trial in 1994, in which he was acquitted in 1995.
