(CNN) Jury deliberations in the trial of Mexican druglord Joaquin "El Chapo" Guzmán stretched into a second week Monday as jurors worked their way through nearly two and a half months of testimony.

Guzmán, 61, faces 10 counts, including engaging in a continuing criminal enterprise, conspiracy to launder the proceeds from narcotics, international distribution of cocaine, heroin, marijuana and other drugs, and use of firearms. He has pleaded not guilty and could be sentenced to life in prison if convicted.

Jurors, who are partially sequestered, deliberated for four days last week. US marshals escort them to and from US District Court in Brooklyn each day. A sworn court officer guards the door of the room where they work, and lunch gets delivered.

The twelve jurors -- eight women and four men -- deliberated until 4:15 p.m. Monday without reaching a verdict. They asked to hear testimony from two law enforcement witnesses, including a DEA agent who described several shipments of cocaine. DEA agent Scott Schoonover testified that some of the seizures were among the largest of his 30-year drug interdiction career.

Guzmán was brought into court Monday for some of the questions. Each day of deliberations is another day he does not have to spend in solitary confinement. And he gets to see his wife, Emma. He smiled and waved at her Monday in the courtroom.
