"Even if we had put surveillance on her and she decided to go to Mexico, we wouldn't have had probable cause to stop her," Maj. Max Geron of the crimes against persons division said in October. "We got the [arrest] warrant as soon as we had probable cause."

Cortes, 24, has said that she didn't know Hatcher would be killed. She told police that Delgado agreed to pay her $500 to drive Love to rob Hatcher.

She told detectives that Delgado used an iPhone to track Hatcher's cellphone location before the slaying.

Cortes faces a capital murder charge and is being held at the Dallas County Jail in lieu of $500,000 bail.

Love, 32, was arrested Oct. 2 after police said they found the murder weapon, a .40-caliber Smith & Wesson pistol, under the front seat of his car.

Love faces a capital murder charge and a federal weapons charge and is being held in lieu of $2.5 million bail. He has previously been convicted of aggravated assault, aggravated robbery and burglary of a residence in Tennessee.

Delgado was the ninth woman to be placed on the FBI's Ten Most Wanted Fugitives List since its creation in 1950. A reward of $100,000 was being offered for information that led to her arrest.

"Delgado's addition to the list underscores the violent and calculated nature of the crime she's accused of committing," said Thomas M. Class Sr., FBI special agent in charge.
