Armando Montaño, a 22-year-old U.S. man working as an intern at The Associated Press bureau in the Mexican capital, was found dead over the weekend, the Mexico City district attorney's office told Efe on Monday.

The body was found Saturday night in an elevator shaft of a building located in the downtown Condesa neighborhood near where the young man lived.

The AP released a note on the death of Montaño, who had arrived in Mexico City in early June.

According to the AP director for Latin America, Marjorie Miller, the young man was not on an assignment to cover any particular news story at the time he lost his life.

According to the note, the intern always showed enthusiasm and passion for his work and during his short time in the capital covered various stories, including the case of three federal police slain by three of their fellow cops at the Mexico City airport during an investigation into a drug-trafficking ring.

For their part, officials at the U.S. Embassy in the Mexican capital said they were following closely the investigation into Montaño's death. EFE
