(CNN) — The lead Mexican investigator in the Falcon Lake case, Rolando Armando Flores Villegas, has been killed, his severed head delivered Tuesday in a suitcase to the Mexican military, officials told CNN. “His head was delivered to the army garrison this morning in a suitcase after he failed to report back home last night,” Zapata County, Texas, Sheriff Sigifredo Gonzalez Jr. said.
A spokesman for the attorney general of Tamaulipas state in Mexico, Ruben Dario-Rios, confirmed the killing Tuesday afternoon in a telephone interview. The report came a day after authorities in the Tamaulipas state attorney general’s office gave conflicting information on whether authorities were pursuing a pair of suspects in the case of David Michael Hartley’s disappearance.
Hartley’s wife, Tiffany, told authorities that her husband was fatally shot September 30 during a sightseeing trip the two were taking on Falcon Lake, which straddles the border. Eva Rodriguez, Flores’ secretary, said the news of his death came as a surprise. “We saw [Rolando] last night,” she said. “After he came back [from the search for Hartley] we were all together here in the office. That was the last time any of us saw him.”
She said she was not aware that Flores — whom she described as “very dedicated to his job” — had received any threats from narcotraffickers.
“What can you do?” she asked. “We’re still going to be here. We still have to work.”
Gosh, it seems we may have terrorists on the border.
