DALLAS -- The FBI announced Wednesday that it has officially added Brenda Delgado to its Ten Most Wanted Fugitives list.
During a news conference, officials said a $100,000 reward is being offered for information leading to an arrest. Delgado is wanted for the murder of Dr. Kendra Hatcher, who was murdered on September 2 in the parking garage of her Uptown apartment building.
Delgado's addition to the Most Wanated list "underscores violent and calculative nature of the crime she's accused of committing," the FBI said.
Police have arrested two other people in the case. Crystal Cortes, who police say drove the get away car, is already in jail. The alleged gunman, Kristopher Love, was also arrested.
Dallas police say Delgado was the mastermind behind the plot to kill Dr. Hatcher; the motive supposedly involved Hatcher's boyfriend at the time of her murder, who was Delgado's ex-boyfriend.
Dr. Hatcher was dating Delgado's ex-boyfriend, and police say she was jealous, so she hired a hit man and convinced Cortes to help her.
In Dallas last November, we asked the Mexican Consul General Sergio Hayakawa why Delgado had not been arrested.
"I don't know why she hasn't been arrested. I don't know if they know exactly where she is at," he said.
Dallas police questioned Delgado within days of the shooting, and even arrested her on outstanding traffic warrants.
The get-away car driver, Cortes, implicated her, but Dallas police let Delgado go, saying they didn't have enough evidence to charge her in the case. They also did not keep her under surveillance.
Multiple sources tell WFAA they believe Delgado fled to Mexico, where she has family.
Cortes' brother met with Dallas police homicide detectives and recorded part of the conversation. The detective is heard on the recording telling the Cortes family they can easily pick up Delgado.
"We know where she is," the detective says. "We can arrest her when it's time."
But weeks later, Delgado is still on the run.
The FBI is now in charge of the case and working with Mexican authorities to bring her in.
"Between Mexico and U.S. we have a lot of international cooperation in these cases," Consul General Hayakawa said.
The Mexican Consulate tells WFAA there is an Interpol warrant for Delgado, so it's up to U.S. federal authorities working with Mexican police to arrest her. But returning her to Dallas may not be easy.
It's complicated by the fact that Delgado was born in Mexico and is a naturalized U.S. citizen, which means Mexico considers her a citizen and won't extradite her unless there is an agreement in place saying prosecutors won't seek the death penalty.
Hayakawa says,"Because our constitution doesn't have the capital murder or death penalty, our government asks for the U.S. government put in writing that they are not looking for the death penalty," Hayakawa said.
Delgado is the 506th person to be added to the FBI's list. Ninety-three percent of them have been arrested.
