While the males are responsible and must be held accountable her parents share some of the culpability. What responsible 13 year (7th /8th grader) old parents let them hang out with 17 and 18 year olds (juniors and seniors)?
Perhaps they didn’t know? When I was in HS, both my parents worked. They couldn’t quit their jobs just so they could follow me around 24 hours a day.
Anyone who expects better judgement from the 13 year old than the 18 year olds is weird
