Dedham man told police to ‘go ahead and check’ his SUV. They found heroin inside.

A Dedham man on Wednesday admitted to a charge related to the sale of heroin and fentanyl, a lethal combination of drugs that has fueled the overdose crisis in Massachusetts.

Manuel Rosario Herrera, 23, pleaded guilty in US District Court in Boston to possession with with intent to distribute 100 grams or more of heroin and fentanyl, cocaine, and cocaine base, legal filings show.

Herrera faces sentencing on June 6.


An indictment filed in the case said he possessed the drugs with intent to distribute in December 2016 in Dedham and elsewhere in Massachusetts.

Public health and law enforcement officials have repeatedly cited heroin mixed with fentanyl as a major driver of the overdose crisis that has claimed thousands of lives in Massachusetts in recent years.

Court filings in the case show Herrera’s arrest arose out of law enforcement surveillance of a drug trafficking crew operating out of the Boston, Dedham, and Revere areas.

Investigators spotted Herrera leaving a residence under surveillance with a small white plastic bag, records show. He put the bag in the trunk of an SUV and drove away and was stopped soon afterward, according to ruling in the case by Judge Allison D. Burroughs.

Burroughs wrote that Herrera was frisked, and a state trooper removed $2,000 cash from his pocket. Asked if there were weapons in the vehicle, Herrera said no and told the trooper to “go ahead and check,” Burroughs wrote.


The trooper obliged and found “a plastic bag that contained what he believed to be heroin” inside the vehicle, among other items, the ruling said.

In the ruling, Burroughs denied Herrera’s motion to suppress evidence from the search, with the exception of the $2,000.

Herrera had said in a a prior affidavit that “I never consented to the search of my person or the vehicle.”

He’s being held pending sentencing.
