If the arrest was in Dallas County, you can look on their website (www.dallascounty.org) to see if there is a case pending against you. If the case is in another county, you may be able to check their website. If not, call a defense attorney in that county to see what they can find out for you.
If the case was filed back then, it hasn't gone away. It's just sitting there with an active warrant. If the case wasn't filed, the statute of limitations has expired.

Contact a lawyer who is local to where you were charged. The lawyer can access the information about the case - perhaps online or at least in the clerk's office - and tell you the status and how you should proceed.
There is great chance given the level of offense that there is a warrant for your arrest and if you enter the U.S., you will be arrested.
