It is unclear by the article but what you wanna bet this was the in-laws talking bad about their daughter-in-law?
Either way they should not have said this to a 13 year old. He is too young to understand adult things and in his eyes Mom is everything.
because Proper told them that “his friend had shot and killed his grandparents,” the complaint said.

so he lied about killing them... trying initially to blame his friend.
...so, i would doubt all the rest he said, in an attempt to “blame the victims”.
it’s quite possible, they didn’t say anything at all bad about the Mother.
(and in fact, may have scolded the boy, who deserved that and more!)
You really think this is what happened? Seriously?
In reality, this double murder took a lot of planning and premeditation.
He just, on the spur of the moment, found a set of boltcutters and used them to open a gun safe? His grandfather just felt like going out for pizza on a whim that one night, leaving him alone with his grandmother? He just happened to have his earphones in when he snuck up behind grandma and killed her? He only wounded grandpa first and hesitated before killing him?
Everything about this story stinks of an attorney trying to build a plausible scenario to support a claim of second-degree murder versus first degree murder.
Think about it for a few minutes. Let it sink in.
The murderer's last name is Proper.
The mother's current last name is Kapp.
The murder victims' last name was Fross.
So it's possible that she was the daughter - i.e., her last name was Fross and is now Kapp and may have been at one time Proper or she may have simply given birth to Proper's child without benefit of marriage.
Or she was the daughter-in-law and was once involved with Fross, and then maybe with Proper and then maybe with Kapp?
But the most plausible explanation is that she is their biological daughter, since it is possible her name was Fross, but it is unlikely that they had a son with the last name of either Proper or Kapp.
