Stuck on mission story

[PTPetisco]

Guys. Sorry if this question already had been made.

I'm stuck in the story missions. Theres no missions left to do, has no one are marked in the map.

I just made the mission ...Pest Control, and got 82 missions done. The list shows charactrs missions like this:

Roman mission progress . 73.33%
Francis mission progresso . 83.33%
Gerry mission progress - 40%

I read somewhere that sometimes there's a glitch that the letter on the map is hide, but in the character location there's the mission icon. The problem is that I don't know these locations. There's some good maps in the internet, but concerning the major characters, it doesn't show then.

Anyone can give some tips, please?

Thanks
