Looks like American actor, David Keith
Shawn Roberts is the splitting image of 1980s American actor, David Keith.

Keith also played a supporting role in the Stephen King thriller, "Fire Starter", from the mid-80s.
In Resident Evil, Shawn Roberts is completely unrecognizable.
Shawn Roberts looks like he could be the brother of the actor who plays the ill-fated bridge navigator on STAR TREK: FIRST CONTACT (1996).
