You might want to put that in a spoiler for the folks who haven't seen it yet.

Spoiler for answer:

Anyway, the death note requires that the user knows the victim's name and face.

Chief Yagami is the only one who saw Mello's face; Light only knows his name, so he can't use the Death Note on Mello.

A sketch isn't enough to count as knowing the face.
