The momma won't come back if your fiance has touched them. I would take them to the vet ASAP!!!!!

What kind of rodent is it?-a mole, a rat, or what? If I were you, I would give them a couple drops of whole milk or something until you can reach the vet.

Make sure to keep them warm and safe from any animals.

Good Luck, and my prayers are with you and the babies!

ps. I would post this in pet general also, you will get more help!-everywhere on PT, and in you siggy, leave a quick note!
