Alfredo Ramirez-Rosas was arrested by the United States Marshall's Office and is awaiting extradition back to the US, according to the Tomball Police Department.
Rosas' arrest comes nearly 20 years after the murder of Mildred Stallones, a retired Tomball School Teacher/Librarian.
The Tomball Police Department says it worked with various federal law enforcement agencies and Mexican officials in an effort to find Rosas.
After the Harris County District Attorney's Office notified police of the arrest, Tomball Police Chief called Stallones' son and told him: "I cannot imagine what it has been like for you and your family to endured this nightmare, however I assure you this has been very personal for us too! Although this does not make the emotional wounds go away, I am hopeful that the capture of Ramirez-Rosas helps us all at least a little bit ? knowing that he is going to be held to some level of accountability."
