Executing a criminal background check is important, not only for your safety but for the safety of your family and business as well. With that said, the first place to look for criminal reports is with the local police department or your own Sheriff’s office. More often than not, if the person was arrested, you can get a copy of the arrest report or make a request for one. Siskiyou county arrest records are available from the Sheriff’s Office. You can obtain the report via in-person or accessing the In Custody Information search tool provided through the Sheriff’s website. If you will be accessing it through online, you need to have MS Silverlight installed in your computer to be able to access the database. If you do not have one installed, you can download it from the site free.
