In the opinion of police detective/profilers working on the case, the brutality and manner of the killing indicated that it was carried out either by a woman or a homosexual, Callaghan stated."
This sentence caught my eye.
Just how does a homosexual or a woman murder someone, and how does their manner of murder contrast with that of a heterosexual man??
This sentence does not make a lot of sense to me. It seems to me that the police should report on "the facts...just the facts, ma'am", and leave speculation -- es[pecially speculation that, on its surface, is somewhat non-sensical to the airheads in the media.
It's a criminological truism that women and homosexuals are far more violent (when spurred to action of this sort) than heterosexual males. Typical difference has to do with the number of wounds: women and homosexuals MORE, hetero men less.
A hetero man TYPICALLY will shoot only to kill and then stop shooting.
There are some exceptions, but they typically 'prove the rule' rather than disprove it.
