My Nephew Lied About My Niece Selling Drugs To Her Students To Get Her To Lose Her Phd. What Should I Do?

Hi, Location: Boston. My nephew lives with his parents. His sister, my niece, is in her final year of her PHD program.

My nephew can be the sweetest person alive, except when he drinks and does dr-gs. He becomes deranged. I very recently found out that he sent a very formal letter to the department head stating that my niece has done things like abuse him physically, with pictures of bruises I know he received playing sports, and that she also deals c-ke to her students. He created two fake texts, one of which included the number of his dealer, and attached them, along with the pictures to the email which he sent to her department head in a blackout rage. The texts included asking for vials of c-ke and a text that didn't have any information but seemed to be probably cropped from a text from his dealer.

The first letter he sent was very official seeming. However, throughout the night, he sent the department head more emails (up until 6 in the morning), which did not seem coherent and contradicted what he said throughout the night when he was blackout. He also sent an email meant for my niece saying he was going to ruin her life, etc. Everything he accused my niece of, except stating she went through a breakup is false. Due to our unique family structure, we are super close in age and she would never do anything like that.

When he woke up, he apparently didn't remember any of it and when he saw the emails, he immediately contacted the department head, explained he was in an alcoholic blackout and irrationally furious at my niece and he took back everything. He stated that every statement he made about her was false and under the influence. He admitted to faking the texts off a site and that the bruises were not from her but sports.

Obviously, this is very serious. He is going to detox and rehab now, finally. However, I am terrified for my niece.

The department head is obligated to report this and everything sent. There will be a hearing. If it wasn't for the two texts citing c-ke and the pictures, I wouldn't be so afraid because he eventually just sounded deranged. There also wouldn't be any actual evidence because she's never done what he has accused her of doing.

Is there anything my family can do to help my niece before the hearing or is her PHD and career just over because of the unforgivable actions of my nephew?

Please please please help.
