The families of two teen murder victims in Houston, express relief in the execution of Jose Medellin. The execution of the Mexican-national sparked international debate because Medellin did not have immediate access to the mexican consulate. Texas courts say Medellin did not try to invoke his right to consulate until four years after his arrest. By then he'd already been convicted. The case attracted worldwide attention after the International Court of Justice said Medellin and about 50 other Mexicans on death row in the United States should have new hearings in U.S. courts to determine if the 1963 Vienna Convention treaty was violated during their arrests. Medellin's execution late last night was delayed for about four hours while the U.S. Supreme Court reviewed his appeal. Medellin took part in the 1993 gang rape and murders of 14-year-old Jennifer Ertman and 16-year-old Elizabeth Pena. In a final statement before his execution, Medellin apologized to the victim's families saying, ""I'm sorry my actions caused you pain, I hope this brings you the closure that you seek." Medellin was 18 at the time of the crime. Of the six involved with the murders, three were sentenced to death. One was executed two years ago, an execution date for Peter Cantu has not be set. Two others involved in the attack received life in prison. Medellin's brother, Vernancio, also took part in the murders and was 14-years-old at the time. He was sentenced to 40 years in prison.
