"Someone" the "someone lvl10" has Fallen

[hdm]

How to remove this shit ? "Our hero has fallen", I want to know how to remove the old guy speaking it and the msg that appears, "Mountain King lvl 10 has fallen".

Object editor => Stats - Hero - Hide hero death message.
If that doesn't mute the sound as well (I think it should), then you may as well try to import an empty sound file as a replacement for the generic one.
