You could spend hours upon hours digging around a variety of different websites for arrest records for Cass County and the worst thing is, you might never find them. One reason for this is that a full criminal background check can be obtained only by filling out the proper paperwork, and by getting the explicit consent of the person whose background you apparently need to have access to.
However, that doesnt mean that all arrest records are unobtainable. In fact, there is an online resource that actually specializes in getting everyday citizens the records of people that are currently in jail. While this search tool cannot provide an extensive background, it will nonetheless tell you what persons currently in jail did to land themselves there, as well as some other personal information about them. You can find this tool here: https://offender.tdcj.texas.gov/OffenderSearch/index.jsp .
Unfortunately, there isnt a resource quite like this for getting the arrest warrant information for every person in the state. Because of a lack for any statewide search tools like this, you will be best off by simply contacting the sheriff of Cass County for arrest warrants in that county. You may do so by calling 903-756-7511.
You should be aware that the sheriff may ask that you visit the station in person, or even outright refuse to give you this information. If you run into this kind of problem, we advise contacting a civil defense attorney as quickly as possible.
