It wasn't a gun, knife, baseball bat, or even Samurai Sword that ended the life of a 59 year old University of Houston professor.

According to early reports, Ana Trujillo and Alf Stefan Andersson, went out for drinks, then got into a disagreement, before ending up back at Andersson's home.

Police were called to the residence in the wee morning hours to an "assault in progress", where Andersson was pronounced dead at the scene with ten puncture wounds to his head, and fifteen along his face, arms and neck.  The alleged murder weapon being a stiletto heal.

For know, Trujillo is claiming self defense, but with at least 25 stab wounds being counted, the Houston based prosecutor is charging her with murder.
