Mexican authorities say a government-owned Learjet has crashed into a lake east of Mexico City, killing two pilots.
The crash late Sunday was the second involving a federal jet in just over a month.
Emergency workers were trying Monday to recover the body of the co-pilot from the lake. The Associated Press reports the body of the pilot has already been recovered.
Last month, Mexico's interior minister, Juan Camilo Mourino, and the former prosecutor for drug crimes, Juan Luis Santiago Vasconcelos, were among 15 people who died when a government Learjet crashed into evening rush hour traffic in Mexico City.
Mexican Transportation Minister Luis Tellez said there was no evidence to suggest that the crash on November 4 was caused intentionally, but authorities were investigating.
