Game-breaking bug in PQ1?

[Nintenfrog]

I am stuck after visiting Marie in the prison. I am called to go to Cotton Cove but whenever I try to stop there the car drives by and I get the message that I have to drop the suspects in the jail first, and I am carrying none.

I don't find any info about this on the internet. Any solution?

Here with the same problem, guess there's no solution?!
