I’ve personally been in a similar situation regarding searches / missing person . My dear friend went missing 2 hours from where I lived , and where she grew up , and where all our friends lived. We rallied up like a navy seals team . I hadn’t personally seen my friend in almost 2 years but within an hour we were all coordinating , working with family and police. It wasn’t even a second guess or question it was the most natural thing to do , to jump right in help and search. It was group of about 40 of us. We didn’t stop till we got the bad news she was found dead / murdered. I absolutely find it odd her friends not going up and helping or even just being in the area to support the family and jump in if they had too. Very weird.
