Swedish Ali Boulala broke through with a bang on the international skateboarding scene in the mid-90s.

Together with his team, he embarked on a ten-year world tour filled with skateboarding, fame and limitless partying with alcohol and drugs.

But life and career took a sudden turn on March 7, 2007 in Melbourne, Australia.

After a night of partying, Ali Boulala and friend Shane Cross were involved in a tragic motorcycle accident.

The accident was so serious that Shane Cross died and Ali Boulala ended up in a coma for four months.

- I'm lying there in the hospital and I don't understand why I'm lying there.

I don't know how many times it was entered that I had been involved in an accident, then the next time I woke up I had forgotten it, says Boulala and continues:

- I thought the same things, what the hell am I doing here and what the hell has happened?

"Everything would have been much better then"

After he woke up from the coma, Boulala was sentenced to four years in prison for negligence in traffic and causing the death of another.

He was also deported to Sweden.

- The first thing I thought was: I should have died instead of him, everything would have been so much better then.

- But that was not the case.

But I was left as some damn punishment.
