What happened to Sanchez after Suikoden 1?

Do we know what happened to Sanchez after Suikoden 1 ends?

Mathiu prevents Flik from executing him after his betrayal because it will hurt the Liberation Army’s morale. Okay. Sure.

But what happens to him afterwards? Is he simply executed? Is he in Soniere Prison? Is there any mention of him in Suikoden 2 or 3?
