lady -- if you don't know your own background, how are we going to know it?\nBelow is a link to some agencies that provide background checks.  Some of them may be able to pull your history.

There is no place to find free criminal reports.  You'll have to pay someone to research (do a background check) to get that kind of information.  Well, if you are resourceful and have a lot of time, you can do it yourself, but it will take a lot of reading, making contacts in the court system and clerk's office.

If they are currently in jail, you can find out everything for free on their prison's website.\n\nIf not, you can do crimial background checks online....of course they cost.

There are on line businesses that will give you any available public info on a person. The often have names like "find anyone now" or "find anything or anyone". The service often cost $29.99 to join. Look for one that offers a "guarantee to find" service. If your friend is under 18, you might need to try to locate an adult family member of his to find him. Good Luck

Break into the records building...\n\nActually there are ways to do background checks on people, businesses hiring do this all the time.  A little searching will probably turn up something, but don't expect it to be free.

Not officially from the police.  Try the local newspaper records, if you  know his name, then its easy.

These things are probably free, but aren't generally online.  Most of the records you're talking about are public record, and you can get copies at the relevant courthouse or police department, but these institutions don't tend to go through the time or expense of putting the information online.  \n\nIf you want to check, look up the institution which would have created the records you're looking for: county courthouse, etc.  See if they've got an online document repository.  If they don't, give them a call and the clerk will be able to help you.

look up the corrections site for your state, it usually has records of current criminals for free. Michigan does, but I noticed colorado doesn't so It will depend on your state.

Go to the county courthouse and ask for the records department.  The bureaucrat on duty may not be of much help, but the records are there for your perusal--for free.
