In another series of appeals, Mr. Guzmán discussed the deployment of a Kartelloperator named Gato to bribe a new commander of the Federal Police.
"Does he receive the monthly payment?" Asked the kingpin.
"Yes," Gato said, "he receives the monthly payment.
In an astonishing moment, Gato handed the commando the phone himself.
In the recording, Mr. Guzmán told the man that Gato from the company "asked the commander to take care of him."
"What Anything we can do for you, you can count on it, "said Mr. Guzmán, and the commander replied," You have a friend here. "
One of Mr. Guzmán's Colombian suppliers, Jorge Cifuentes, made the Kingpin an IT expert, saying last month that Mr. Rodriguez had promised to organize secure communications for the entire leadership of the cartel. Mr Marston said on Tuesday that his system uses VoiP or Voice over Internet Protocol and is only accessible to those within the network. According to Mr. Cifuentes, Mr. Guzmán could also log in via his hiding place in the mountains of the Sierra Madre via WLAN.
But F.B.I. A few days after Mr. Guzmán called her, the agents could hear phone calls, Marston said. From April 2011 to January 2012, the US authorities, with the help of Dutch officials, received a total of 1,500 calls. Those who were believed to have been placed by Mr. Guzmán had been authenticated, Marston told the jurors, comparing the high, nasal voice of the calls with other recordings of the Kingpin, including a video interview he was rolling Stone gave in October 2015.
