An illegal immigrant from Honduras who claimed his treaty rights were violated when he was arrested for a robbery-murder near Dallas was executed Thursday evening.

"God forgive them, receive my spirit," Heliberto Chi said in English. In Spanish, he told a friend watching through a window that he loved him and appreciated his hard work. He appeared to be whispering a prayer in Spanish with a tear at the corner of his right eye as the lethal drugs began to take effect.

One of Chi's cousins, who was among the witnesses, sobbed uncontrollably. Two sons of his victims watched through another window and Chi glanced at them briefly but didn't appear to acknowledge them. Chi was pronounced dead nine minutes later at 6:25 p.m. CDT.

He murdered his former boss, Armand Paliotta, during a 2001 robbery at an Arlington men's clothing store where Chi had once worked. An employee was wounded trying to run away and another hid among clothing racks and called 911 for help.

Chi went on the run with his 18-year-old pregnant girlfriend. She turned him in California about six weeks later for assaulting her and told authorities he was wanted for murder in Texas.

Lawyers for Chi had claimed in appeals to the U.S. Supreme Court that he should have been told he could get legal assistance from the Honduran consulate when he was extradited to Texas to face charges.

The Supreme Court, ruling about 2 1/2 hours before his scheduled execution time, rejected his appeal without dissent. The Texas Court of Criminal Appeals, the state's highest criminal court, rejected a similar appeal late Wednesday.
