I am on my phone now and don't know how to link but other posters have linked several cases where the parents or others in the home were murdered and then young children kidnapped by the perp.
Of course Joseph Duncan murdered three...mother..boyfriend and teen son before kidnapping Shasta and Dylan. After torturing and raping Dylan for 6 weeks he murdered him as well.
The Short parents were murdered inside of their home and their little girl kidnapped and later found murdered.
In one case a pedophile tried to burn down the home hoping to murder the little girl's family then he kidnapped the child and she is presumed dead at the hands of the pedophile.
There are more cases than these though. Perhaps you could search in the prior threads to find some of them or do a Google search.
I would do it but as I said i just started posting on my phone and haven't learned how to do links yet.
Imo
The Short murders have yet to be solved and it was years ago but it sure is similar to this case. JMO
