guided crackhead

A crackhead (or other person of violent, irrational behavior, such as a crystal meth addict) who is intentionally given information as to where a particularly choice/valuable target may available by theft or armed robbery. The implicitly or explicitly intended victim, however, may be someone who it is known will be home at the time of the assault, to be disposed of before the valuables are taken. In this manner the crackhead is used as a 'fire-and-forget' weapon, like a guided missile.
