Not sure which suicide winder method you're referring too, but it isn't enough to simply die. You need to be killed by a ship that will collect the bounty on you.
Typically this means the issuing faction's system autority vessels or, and this is the quickest, by the station security where the issuing entity is the controlling faction. If going the ship route, they have to scan you and see that you are wanted. This is also easiest hanging around the station or in a haz res.
So, go to their station, get scanned and wait for shangrila.
