Refusing accident insurance money

Hello all, I have a scenario that I wanted to see if anyone could provide some insight on. Here’s the situation (names are changed)

The evening of a party, John (18) was driving a truck around some country roads because Logan (17) wanted to steal road signs. This was an underage party and both were inebriated, from what witnesses have said, Logan was insistent on getting into a friend’s truck and driving to take the signs. This truck was accessible as it has a code door and the keys are kept inside. Logan was, as witnesses say, blackout drunk. John knew Logan wouldn’t back down on driving so John drove Logan to find these signs. John was also inebriated but appeared to be less so.

John had driven Logan around (with Logan sitting in the bed of the truck) to let Logan take signs. The pair were headed back to the party when John hit a dark curve, veered to the left of the road, and hit a culvert. The truck was then airborne for maybe 20 feet and turned on its side, hitting a tree straight on. It’s assumed that when the truck hit the culvert, Logan was thrown from the bed of the truck and hit a guy wire, severing his arm from the elbow down. John’s neck is said to have been broken upon hitting the culvert and the truck lifting into the air violently. Their friends heard the sound of the accident and made their way to the scene, where John was determined to have already passed and Logan was unconscious but still alive.

This occurrence little over a year ago and in the entire time since the accident, Logan has declared that he remembers nothing of that night and denies any wrongdoing. I am a member of John’s family and we have been dealing with not only the loss of John, but also a very stressful legal situation. Logan’s family has decided to refuse our insurance’s offer and has been going for my family for things we don’t even have. They have been harassing our insurance, as in literally calling constantly and yelling at the poor woman to increase the amount of money they can offer, which is $50,000. Logan’s father has called and demanded that our insurance give him our mothers’s contact information and has frequently called just to tell our insurance to let us know they still won’t accept the money our insurance can give to them.

In all of the grieving, at least once a month we have been called and told these things. A few months ago, Logan’s family’s lawyer sent an affidavit for our mom to sign confirming that she has no property or assets of value (which she doesn’t). She signed it and we just heard back that they’re refusing the affidavit and still want more money.

Here’s where I would so greatly appreciate any advice.

• I first want to ask, since John was 18 at the time of the accident, why/how would they be trying to go after our mom’s assets, being that he was legally an adult and owned nothing/had nothing in his name?
• Why are they doing this? For 14 months they’ve been told how much money they can get from our insurance. The affidavit felt like some sort of performative intimidation. I began to look into this online and spiraled, thus why I’m here, and I read something about if time goes on long enough, and insurance decides to close the case, Logan’s family could try to come after us personally for money. Are there any ulterior motives here legally?
• Is there anything we can do as John’s family? John and Logan were good friends before the accident, but Logan’s family has completely turned against us. They have not once spoken to us except through other people in a way that absolutely seems intimidating. We’re tired and angry and still grieving. Is there anything we could do legally to at least separate them from us?
