With regards to the multiple sharp force injuries, I was wondering if this is considered "overkill" which has it's own meaning as to motive. Anyone here good at crime scene analysis? I did find this which seems close.
- "Disorganized offenders: These criminals usually live alone or with a relative, possess lower-than-average intelligence, are unemployed or work at menial jobs, and often have mental illnesses. They act impulsively, or as if they have little control over their fantasy-driven needs. They rarely use ruses to gain the victim’s confidence, but rather attack with sudden violence, overwhelming the victim. The crime scene often is messy and chaotic. This type of offender doesn’t plan ahead or bring tools along, but rather uses whatever is handy. As killers, they typically leave the body at the scene and exert little effort to avoid leaving behind evidence. Some have sexual contact with the victim after killing him or her."
"Overkill usually is personal, with anger as the common underlying drive."
