SAN ANTONIO – A 22-year-old woman was found guilty Tuesday in the execution-style deaths of two men.

Jurors deliberated for two hours before finding Antoinette Martinez guilty of capital murder in the June 2014 slayings of two men.

Prosecutors said Martinez lured the men to her apartment with a promise of sex. Instead, she and her boyfriend, Cameo Clines, robbed the men and took them to remote rural fields and shot them to death.

The conviction means Martinez must spend the rest of her life in prison without the possibility of parole.

"She is a ruthless killer with no remorse," prosecutor Mari Janssen told jurors during closing arguments. "She is cunning and dangerous."

Martinez's attorney, Mark McKay, countered by saying his client was a "Woman in love manipulated by her boyfriend."

Prosecutor Josh Somers countered by saying, "The only people trying to be manipulated here? Cameo and Antoinette tried to manipulate you."

Clines testified that he did the shooting and that Martinez should have her charge reduced to murder from the more serious charge of capital murder.

He pleaded guilty to the killings last year and is serving two life sentences.
