My step-son and daughter-in-law are separated but not divorsed yet. She and our 2 grandsons moved in with us(my husband and I). She left on Sat. evening with us babysitting the boys. We have not heard from her since except for 1 text message she sent on Sunday afternoon. It is now Mon. afternoon and she still has not shown up or called. Can Abandonment charges be placed on the mother?
