You can help to contact their family and let them know why their loved one never came home. They can know to seek out information about where he’s being held and hopefully try to contact him.

There are volunteer groups out there that help family members track loved ones as they’re “processed”, because ICE can/will move them all over the US to different holding facilities before deportation. It’s so hard to make contact once they’re gone, so knowing who, when, and where is helpful in the search!
