U.S.: Accused Teen Hit Man In Mexico Is An American Citizen

(CNN)

A 14-year-old accused of ruthless killings on behalf of a Mexican drug cartel boss is a U.S. citizen, a U.S. State Department spokeswoman said Monday.

Gini Staub would not provide any further information.

"We have confirmed the boy's U.S. citizenship but can't say anything more about the boy's situation in the absence of a (provisional arrest warrant) signed by at least one of the parents," Staub said.

Earlier, Staub said that the boy, once his citizenship was confirmed, would be given "all appropriate consular assistance, just like we would for any U.S. citizen arrested and incarcerated overseas." Assistance would include prison visits, information on local attorneys and checks on his welfare, she said.

The teen -- reportedly carrying a birth certificate issued in San Diego -- and two of his sisters were detained Thursday at an airport in central Mexico after an anonymous tip alerted authorities he was heading to Tijuana, Mexico, local media reported.

A spokeswoman for the Mexican attorney general's office said authorities detained the 14-year-old Thursday evening on suspicion of working as a drug-cartel hit man, but declined to provide details.

But the boy faced a battery of questions from reporters after he was detained, answering questions point-blank as camera flashes lit his face.

"I slit their throats," he said, describing what he said was the killing of four people.

The teen told reporters after his capture Thursday night that he was an orphan who joined the Pacifico Sur drug cartel when he was 12. He said Julio "El Negro" Padilla, one of the group's alleged leaders, threatened him.
