You have not given enough information about the situation for people to even comment about it. It is obviously something serious enough for the school to be concerned and for you to be too embarrassed to put into your post. But I have serious concerns that you would consider to model behaviors that are inappropriate like lying. That shocks me, when it appears that the problem with the school stems from LYING. One of the hardest lessons in life is know that there is a consequence for your actions. You teach her now that there is a way around, you will start a chain reaction that will last her lifetime. Think hard about this. Your decision to lie for her is NOT good.
Your next step after she "suffers the aftermath" is for you to look at your daughter and decide WHY she made such poor choices. Was it your parenting OR is there something she needs help with? Often bad behavior is a way of looking for attention. She may need extra TLC right now and you need to figure out what she needs.
