PITMAN, N.J. (AP) — Autopsy results confirm a southern New Jersey man killed his wife and their young son before hanging himself inside their home (see previous story).

But it’s unclear why 49-year-old Francis Adolf committed the slayings. Gloucester County prosecutors have said he left writings indicating he intended to harm himself and family members but haven’t provided details.
