Police are saying the shooting appears to be random. Sherwin had no contact with the people he killed before the shooting.

Snipped and bolded by me:
“Police say Sherwin had no contact with the people he killed before the shooting, police said.
Adam Morehouse, the brother of Sarah Schmidt, says the family did not know the attacker at all.
"We didn't know the suspect. The suspect didn't know us. We don't know of any interaction that occurred. It was simply this individual woke up this morning and decided to pick a tent and walk into that tent where my sister and her family were sleeping and never got a chance to wake up," Morehouse told WHBF-TV.
The family says they're prepared to accept that some questions will go unanswered. That includes why the suspect would carry out such an attack.
"I'm sure we're all going to end up processing it in due time our own way. And for right now, we're able to basically deal with it however we possibly can," Morehouse said.
The Iowa Division of Criminal Investigation said Sherwin's parents are cooperating with the investigation. They are from La Vista, Nebraska, an Omaha suburb. Sherwin lived with them.
DCI said they are working to find out why this happened.
"Sometimes, motives aren't revealed, so to say, or discovered. And at this time, we don't have any information that would lead us to a motive in this," Iowa DCI Assistant Director Mitch Mortvedt said.
Police in La Vista did go to his house for a welfare check Friday, but his parents were not home.”
I’m confused about the bolded part. Why would police in Nebraska go to the Sherwin residence for a “welfare check”? When did they do this welfare check? If they visited the Sherwin residence before the murders of the Schmidts at the campground in Iowa, then there was likely something (like an online post, text message, phone call…?) that caused someone close to the Sherwins to request the family be checked on.
If the welfare check happened AFTER the murders of the Schmidts, all I can guess is that the Sherwins might’ve been expected home at a certain time, and when they did not arrive as expected, friends/neighbor/family members asked for the welfare check? Or, alternatively, if AS was on leave from a residential program and had been expected to check in (or return) when the camping trip ended, a welfare check might've been requested by someone from that program when he failed to do so?
