HUNTSVILLE — With his final words, “suitcase killer” Rosendo Rodriguez of San Antonio called for the FBI to investigate the Lubbock County district attorney and medical examiner.

After a final statement that took more than seven minutes in which Rodriguez urged onlookers to write other men on death row, called for a boycott of Texas businesses and referenced his Catholic faith, he died by lethal injection.

“The state may have my body but not my soul,” Rodriguez said.

A day after his birthday, the 38-year-old lost a final appeal — which stemmed from claims prosecutors withheld information regarding a lawsuit against the medical examiner — less than half an hour before he was scheduled to die at 6 p.m.

The lethal dose of pentobarbital started flowing at 6:24 p.m., and Rodriguez was pronounced dead 22 minutes later.

“I had the honor and privilege to know many prison guards and staff,” he told onlookers before his death. “I want to thank all of them. I would like for everyone to write the people on death row as they are all good men, and I am very happy I got to know them. All of their lives are worth knowing about.”

“I want everyone to boycott every single business in the state of Texas until all the businesses are pressed to stop the death penalty,” Rodriguez continued. “With that, Lord, I commend my spirit.”

At one point, he decried the “thousands” he alleged were wrongfully convicted by Lubbock County District Attorney Matt Powell.

“This needs to be brought to justice,” he said. Powell declined to address the condemned man’s final words against him.

“Today’s not a good day,” Powell said. “We’re not happy about anything, but like I’ve said all along I certainly think justice was done, that he paid the ultimate price for the crimes he committed. I think it was justice, I certainly do.”

Rodriguez — the fourth man executed this year in Texas — was sent to death row nearly a decade ago for the 2005 slaying of Summer Baldwin, a pregnant sex worker and mother of four.

Workers at the Lubbock city landfill spotted a new suitcase in the trash, opened it and discovered the body of Baldwin. She had been beaten and strangled, and her body was covered in cuts and bruises — roughly 50 blunt force wounds.

The 29-year-old’s death may have stayed a local investigation were it not for the woman’s ties to a federal counterfeiting case in which she’d been a witness.

The feds swooped in, and eventually authorities found records to zero in on a suspect.

Detectives used a barcode label sewn to the luggage to establish it was purchased a day earlier at a Walmart. Debit card records and store surveillance video identified the buyer as Rodriguez, a Marine reservist who’d been in Lubbock for training that included martial arts combat.

When authorities arrested the former fraternity brother at his parents’ home in San Antonio in 2005, Rodriguez admitted to the slaying. But he said he killed the woman in self-defense after she attacked him with a knife for stealing her crack pipe.

In the hours before the murder, the two met up while Rodriguez was visiting Lubbock. He brought the woman back to his room at a Holiday Inn, then raped, beat and strangled her. Then he bought some food, rented a movie and went to sleep before checking out of his hotel room.

After his arrest, according to court records, he also admitted to the 2004 slaying of 16-year-old Joanna Rogers — who was also found in a suitcase in the Lubbock city landfill, according to court records. Later, during trial, jurors heard testimony linking him to five other rapes.

At one point Rodriguez was scheduled to take a plea to avoid the death penalty. But the day before he was to sign the agreement, Rodriguez began claiming he did not understand anything he was told. His lawyer pulled out of the case, the plea deal fell apart and prosecutors decided to seek a death sentence instead.

On appeal, Rodriguez’s attorneys argued that the sex was consensual, that there is no evidence he’d planned to kill the woman and that he had ineffective trial counsel. But the courts rejected his claims and in late 2017 the Supreme Court turned him down.
