Every once in a while, a website comes along that ends up being exactly what you need it to be. For Texas, particularly if you’re searching for arrest records and warrants for Comal County, this website would be that of the Comal County Sheriffs Office.
Housing information above and beyond the call of what other Texas sheriffs believe to be their duty, Comal County makes it easy to find most of the information that deals with arrest records and warrants. First, though, you should probably check out their home page, which can be accessed here: http://www.co.comal.tx.us/so/index.html.
One of the resources that really ought to be universally available but which is only so on a limited basis is that of the Top Ten Most Wanted for any given county. This information can be used to determine who has the strongest arrest warrants out for them (although it is not an exhaustive list!). You can find this page at http://www.co.comal.tx.us/Most%20wanted%20main.htm.
On a similar note, you can even read about the Crime of the Week, which changes every week and can be a story of human interest. This is at http://www.comalcrimestoppers.org/crimeoftheweek.aspx.
To ask the sheriff of Comal County about arrest warrants, you should call their hotline at 800-640-8422.
Unfortunately, one of the things this website does not detail is actual arrest records. Thankfully, you can find complete jail listings, detailed arrest records on this page: https://offender.tdcj.texas.gov/OffenderSearch/index.jsp.
