Reduction in pay for employee who never schedule back

We are a very small business. Here’s my situation: I hired a new employee. One of my tenured employees came in on a weekend (I did pay them both)to help her get comfortable/train, etc before her start date, Monday. She started and...On day 2 she had to leave to take her daughter to Dr appt, Day 6 she left early saying daughter was in hospital- she lied about job responsibilities being completed and I had to pay other staff additional hours to complete. Then Day 7 She sent me a text saying she would not be in due to family emergency. When after 3 days she had not returned to work, I contacted her. She indicated she did not know definitely when she could come back. At this point I shared that I could not hold her position open as we are a VERY SMALL office. It was her decision to say she was “quitting”. My question is: do I have any ability to either lower her pay to minimum-wage or hold some of her pay out and not pay her to re-coop some of my losses for training, etc. This would be her first and only check with us. Thank you!
