Hi,

I seek the movie, but I got only a few memories:

• street gunfight between groups (mafia ?)
• witness (man) watching that gunfight from his window
• the briefcase filled by money lies close to one dead body
• the man carefully took the briefcase and hide it (inside flooring plate ???)
• the man is investigated by inspector and police, but they found nothing

The movie is old, over 20 years, I guess. (French or Italian ???)

Thanks in advance for any suggestion.
