My question involves criminal law for the state of: CAlifornia

I just recently found out my husband and I could possibly be charged with supplying alcohol to minors (my son and daughter) from back in February 2008.

It was my husbands birthday and we were celebrating. My daughter went out with her friends and came home drunk. My son got into our beers.

Since it has been 19 months since this happened can we still be charged with contributing to minors? Or is there a statute of limitations and if so how long is it?

Thank you
