The guards do not attack the crime and murderer by player or NPCs called "guard"?

Sorry for my bad English,first of all...

I nerver found this problem.
Today I found this happened when I test some killing issues.
One of player killed another many many times,and I send both back to town.
And NPCs called the guard and the guard showed up,but guard didn’t attack the murderer,and the murderer system message showed 2 lines：
"Guards can now be called on you!"
"Guards can no longer be called on you."
then only showed just like the image shows:
"Guards can no longer be called on you."
I checked the "GuardedRegion" was "Active" and the player kills 9.
I tried many place of the scripts codes but I can't understand where to fix this?

Could some one help me?Thank a lot!

Well, is the player taged as PK? If i remember, guards only kills red players...

I see a guard bug with NPC mobs, its very annoying =P If you don't SELECT the mob before call guards, tghe guard don't kills it. And if there are 2 mobs on you, and you called guards, it will kills only one. You have to target the other mob and calls guards again. Well, its very sux =P It would be better if you call guards, and the guards searchs for all PKs or agressives mobs on area, what that don't happens.
