US hands over former Mexican cop accused in murders of 43 college students

American authorities handed over a key suspect in the 2014 abduction and killing of 43 college students to their Mexican counterparts after he tried crossing the border without the proper documents. 

Mexico’s National Immigration Institute identified the man only by his first name, but a federal agent later confirmed to The Associated Press on Thursday that he is Alejandro Tenescalco. The institute said he failed to qualify for asylum in the United States.

Tenescalco, a former Mexican police officer, was caught trying to cross the border on Dec. 20.

He was a police supervisor in Iguala, a city in the state of Chilpancingo where students from a rural teachers college were taken by municipal police. Mexican authorities have suggested that corrupt police turned the students over to a drug gang, who killed them and burned their bodies.

Alejandro Encinas, the head of the government Truth Commission, has called Tenescalco “one of the main perpetrators” of the crime.

He faces charges of kidnapping and organized crime. The Mexican government had offered a $500,000 for his arrest. 

The killing of the students drew international outrage and became an example of the endemic violence by brazen drug gangs and corruption throughout Mexico. 

The investigations resulted in the arrests of three soldiers, including a now retired general who had been the army commander in the area when the abductions occurred. Also, then federal Attorney General Jesús Murillo Karam has been accused of inventing the government’s original account based on torture and manipulation of evidence.
