Hi, my name is Tammy and I live in NY. I am currently in an arguement with my oldest son's girlfriend on what she had done tonight. She is 18 years old, and she came to our home tonight with my oldest son. My youngest, 14, asked if he could go with them to visit his aunt and that the girlfriend would bring him home. My oldest son lives with his aunt, so I figured it was okay and let him go. Well, 12:30am comes and he still isn't home and no calls. Aunt's phone isn't working properly and I don't drive. I texted her and said I hope there is a good reason why my 14 year old isn't home yet and she replied: My grandmother wanted me home and he didn't want to come with me so I left him there. So he obviously would miss school if he doesn't come home. I am about to call her mother and tell her her daughter better go pick him up because I left him in HER charge and she will be responsible if anything happens to him. Am I correct? Is she legally responsible for an underage child left in her care?
