You are right they do happen, and I read several articles last year that home invasions by strangers are on the rise all over our nation.
We have seen several home invasions discussed here on WS where victims were brutally beaten and/ or raped and murdered. Most of them had multiple victims in one household.
I remember another case where a guy came into a house to kidnap a young girl. He had never been inside of the home before, but in complete total darkness it took him less than 8 minutes to go in and come out with the child in his arms. IIRC, he kidnapped, raped, and then murdered her.
Home invaders have become viscous even doing gruesome over-kills.
Joe Duncan was willing to murder two adults and a large 12 year old boy in order to kidnap Shasta and Dylan.
Some of these brutes will stop at nothing and let nothing get in their way of taking the child they came for.....
IMO
