The only woman on the FBI's most-wanted fugitives list has been arrested in Mexico.

Brenda Delgado, 33, is suspected of orchestrating the murder-for-hire of a dentist who was in a relationship with her former boyfriend.

Delgado was captured on Friday by agents from Mexico's Criminal Investigations Agency after being on the run for seven months.

She was indicted on capital murder charges after her alleged accomplices shot Kendra Hatcher, 35, in a parking garage in Dallas.

“Although she didn’t pull the trigger herself, she is still responsible for the murder,” said Thomas Class Sr., of the FBI’s Dallas division.

A reward of up to $100,000 was offered for any information leading to her arrest.

Investigators believe that, days before the murder, Delgado discovered her ex-boyfriend and Ms Hatcher were planning to go on holiday to Mexico.

They suspect she planned to kill the dentist for months after finding out Ms Hatcher had met her former boyfriend's parents.

Her co-conspirators Crystal Cortes and Kristopher Love have been arrested and remain in custody. Authorities alleged Cortes and Love were lured by promises of money and a steady supply of drugs from Delgado's cartel sources, CNN reports.

Delgado will be detained in Mexico City, pending proceedings for extradition to Dallas, Texas.
