Two people borrowed money from the same person, wrote an iou, and one person ran away. Now it depends on the specific situation. Leave the money to one person:

1. If the amount borrowed by each person has been stated in the IOU, and the contents of the IOU cannot prove that the other two people have the same repayment obligation, the other party only has the obligation to repay the amount borrowed by itself, but has no obligation to help the other party to repay. Therefore, creditors can only claim rights from the other party according to their respective loan amounts, and cannot require the remaining people to repay them in full.

2. If the amount borrowed by each borrower is not stated on the IOU, but signed by the other two borrowers, or it is clearly stated on the IOU that the two borrowers jointly borrow, the two borrowers have the obligation to jointly repay. If one party can't find it, the creditor can ask the other party to return all the loans.
