Alberto Mora, of Morriston, Florida on Thursday moved to enter a guilty plea to charges of conspiracy to distribute heroin, cocaine and fentanyl and conspiracy to distribute morphine, according to documents filed in the U.S. District Court in Trenton.

Mora, 52, was one of five men arrested on Feb. 5 after a DEA stakeout in Passaic County, according to a criminal complaint originally filed with the federal court in Newark.

Investigators seized more than 77 pounds of suspected heroin and more than 44 pounds of suspected cocaine between two traffic stops and a search warrant served on a tractor-trailer, the complaint states.

Agents conducting surveillance on the location had witnessed men carrying heavy bags out of the tractor-trailer prior to conducting traffic stops on their vehicles, the complaint states.

Mora faces a minimum sentence of 10 years in prison and a maximum sentence of life imprisonment on the first count, which charges him with conspiring to distribute heroin, cocaine and fentanyl. He faces a maximum of 20 years on the second count, which charges him with conspiring to distribute morphine, according to the plea agreement.

In exchange for a guilty plea, the U.S. Attorney's Office won't prosecute Mora on other drug charges, according to the agreement.

Another suspect, Emmanuel Gonzalez, previously also pleaded guilty Sept. 1 to conspiracy charges from the stop and is scheduled to be sentenced Dec. 15 before Judge Peter G. Sheridan in Trenton.

A future court date for Mora has yet to be scheduled, according to court records.
