This is something I would be careful with. I would reach out to the mutual connection and see if they know the person and if so, ask if they would mind introducing you. Reaching out to someone currently in the position for which you've applied can be risky, as you don't know if they're leaving that position on good or bad terms. If you know that it is on good terms (promotion, etc.) congratulate them and think about asking some questions regarding the role; what they enjoyed or what they would've like to have seen done differently, or even what made them successful enough to move into their new role.
