Joseph Facundo and Tony Escobar were caught last Friday in Laredo. They are charged with killing Russell Lopez, 31, in his home on December 20.
Investigators say the two men, along with Amber Thornton, 22, went to Lopez's home to buy drugs. Police say the two men tied up Lopez, and two of his children, and beat him to death with a hammer.
Thornton was arrested last week, but Facundo and Escobar were able to get as far as the international bridge. Both men are being held without bond.
