A 29-year-old Massachusetts man is facing charges in New Hampshire after investigators said he was found with 2 pounds of what police suspect to be fentanyl.In court documents, investigators allege that Eddy Perdomo arranged to sell a kilogram of fentanyl to someone in Ashland over the weekend.The buyer was working with the Drug Enforcement Administration as a confidential source after being arrested a week earlier on a drug trafficking charge, officials said.The source told investigators that they met with their supplier 12 to 15 times in a parking lot off I-93 at exit 24 at about 10 a.m. on Saturdays. The transactions were described as quick, hand-to-hand exchanges through car windows. Investigators said they had their source text Perdomo to meet for 100 "sticks" of fentanyl, which is a little more than two pounds. They said Perdomo arrived as a passenger in a car that had traveled up from Lawrence, Massachusetts.Officials said the suspected drugs were found on the passenger-side floor between Perdomo's feet. "It literally could have been a deadly dose to tens of thousands of Americans, tens of thousands of individuals in this state, absolutely," said Paul Spera of DEA New England.Perdomo had an initial appearance in court Monday and is scheduled to face a judge again Wednesday afternoon.Perdomo was charged with possession with the intent to distribute fentanyl, which could carry a sentence of up to 20 years in prison, at least three years of supervised release and a maximum fine of $1 million. It's unclear if the driver is facing any charges.
