Burglary at rental property

Hi BP, 

Better weather is here so people are out and about! My tenant called me and told me that someone threw a brick at my rental property in Indiana and smashed a window. Its an older window so it will need to be replaced for about $300 M&L. Should I be eating the repair cost on this and or can I pass this on to the tenant? I'm pretty sure the brick thrower is someone she knows but I have no proof. 

Thanks

Brian
