Most likely, her son and her parents do at the least. Even though there's the incident about the tire slashing and his emancipation, he has spoken with love and admiration for his mom since. He's also stated he was with her at his sisters' births (or shortly after), held them, and cared for them over time. Evil stepdaddy may have made the relationship untenable for a responsible 17 year old who went to school, worked, and was able to buy a very nice truck and maintain it. I'd be curious where he lived after he was granted emancipation.
It was evil stepdaddy that stated in the tire slashing that he was "acting like a parent". He clearly had a gigantic control problem and he clearly felt he was ENTITLED to violence and destruction of another's property.
In any event, this woman's estate, who had just been granted a hard fought for divorce, should NOT be left in its entirety to her EX husband even IF he had nothing to do with the heinous murder of her and their 2 children.
