The sister is a moron. She lost her family due to gun violence? Really? Actually your brother in law killed your family, not gun violence, the violence was due to your brother in law alone.
If the gun caused the violence, then lock up the gun and let the person go free.
Sigh. It’s those “violent” guns again...
The other morons are those that donated to their GoFundMe page. Surely they had some assets that the surviving daughter could have liquidated.
