My car ran hot for the first time yesterday!

What is your question?

I have a 2004 Suzuki forenza! I purchased it in February and have had no problems at all with it! However, I let my sis n law borrow my car to go to her daughter's graduation, ( we live in VA daughter's graduation in DC). At 9:45 she calls to tell me my car drove great going up there! At 10:53 she calls to say my car ran hot and there's no antifreeze in it! She says she bought antifreeze to put in my car and it still ran hot, then she said she put water in it and drove to s mechanic who told her my radiator was cracked from left to right
