The new wife of a double murderer screamed “I love you” and flailed against the window as her husband was executed in front of her in Texas.

British law graduate Tiana Krasniqi had married death row inmate James Broadnax just weeks before he died by lethal injection Thursday for killing two men in a 2008 robbery.

The new wife — who struck up her relationship with the killer by writing to him in prison — was inconsolable as he was finally executed hours after the US Supreme Court denied a request to stop it.

“I love you,” she repeatedly screamed as Broadnax, 37, was injected for the double slaying he went to his death insisting he did not commit.

The new bride then threw herself against the death chamber window with her arms spread as her husband gasped and shook his head a final time.

He was declared dead after 21 minutes, with his widow so devastated she had to be helped out of the prison afterwards.

“They killed my husband,” Krasniqi said in a TikTok after the execution.

“My husband suffered so bad from the lethal injection that he had a nose bleed and bruising on his neck. The families laughed as they watched. Is that justice?”

Krasniqi and Broadrax tied the knot in a Texas prison on April 14. The pair had forged a relationship writing letters back and forth over two years as Krasqui lived in London working toward a master’s degree in human rights law, the Dallas Morning News reported.

She had been holding out hope that he would not be executed.

Broadnax was condemned to death for the shooting deaths of two men in 2008 when he was 19 years old. Broadnax and his cousin, Demarius Commings, fatally shot and robbed Stephen Swan and Matthew Butler in the parking lot of Butler’s recording studio in suburban Dallas, prosecutors said.
