<human>: Long story short, two BILs tried to come over here to the US on foot. They were left behind somewhere in Texas because one of the two got violently ill. Last communication with them was yesterday morning (they had a cellphone that they kept turned off because who can charge a cellphone in the desert).

Anyway, my husband and another BIL (who both have valid papers, thanks) flew down to Texas to try and find them, but the lost BILs couldn't give a good location. We think they were picked up by immigration, but I can't find record of them in the system. My husband and other BIL are flying back home today.

My husband has been very distant. We'd had numerous fights over the past couple months since he announced they were trying to come. He knew I didn't want them here. Anyway, he's worried sick about their mom, their aunt, and of course his brothers. 

How the hell do I help here? I told them it's a good thing if immigration got them because then they'll go back home and be with their mom... And he told me I don't understand.

Help. :(

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: two BILs are probably dead or still lost or with immigration because they tried to come without papers. How do I help my husband deal with the uncertainty and/or loss?
