MEXICO CITY (CBSNewYork/AP) — Mexican authorities have arrested the man they believe was responsible for the 2014 killing of a Westchester County man who vanished while heading on his motorcycle to Brazil for the World Cup.

Mexico’s federal police said Tuesday they arrested Adrian Reyes Cadena, the leader of a drug gang in the Pacific coast resort of Zihuatanejo.

A federal official who was not authorized to be quoted by name said Reyes Cadena’s gang apparently thought victim Harry Devert, a 33-year-old stock trader from Pelham, was a U.S. agent.

Devert, a world traveler and adventure blogger, headed down to Mexico on his motorcycle with the hopes of riding to Brazil for the World Cup and then all the way to the tip of South America, according to his travel blog.

He left for his trip from New York City in early December of 2013.

He was last heard from in January of last year when Devert told a friend that he was headed for Zihuatanejo and was being guided by a Mexican military escort.

Devert had also been keeping in close touch with loved ones during his journey and said he was expecting more escorts waiting for him in other towns.

His decomposed remains were found along with his motorcycle months later about 16 miles from Zihuatanejo. The remains were identified through genetic testing.

Authorities also said they recovered a bag nearby containing 10 packets of what appeared to be marijuana and cocaine.

Reyes Cadena led the “Guerrero Guard” gang and was known by the alias “El Tigre.”

He also allegedly oversaw the kidnapping and disappearance of two federal police officers in 2013 and the kidnapping of an Italian businessman in 2014.
