A Worcester man accused of lying to firearms dealers after purchasing several guns plans to plead guilty to firearms charges in federal court Monday.

Authorities say he was unable to account for nine of the 16 purchased guns.

As police investigated 23-year-old Ruben Ramos for allegedly lying to firearms dealers during the purchases they also noted his brother is a known gang member.

Ramos said his brother and other gang members never asked him to buy weapons for them and never asked to borrow one of his guns, authorities said in federal court records.

Ramos is facing five counts of lying to licensing firearms dealers, two counts of making a false statement during firearms purchases and possession of a stolen firearm in federal court.

Records show he plans to plead guilty Monday in a Worcester federal court.

Michael Finnerty, special agent for the U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives, said Ramos listed that he lived in a Worcester Housing Authority apartment in Great Brook Valley when he received a license to carry and firearms identification card from Worcester police in December 2016.

Records show however his mother removed him from the lease at the apartment two years earlier.

Ramos bought 16 guns between May 2017 and May 2018 and on at least five occasions – during which he purchased seven firearms – Ramos provided a false address to the federally licensed firearm dealer, authorities said.

The guns, mostly pistols, one shotgun and one rifle, were purchased from dealers in Berlin, Webster, Worcester and Woburn, authorities said in federal records.

One Glock was purchased during a private sale.

In June 2018, investigators spoke with Ramos as his apartment on Hollis Street.

“When agents interviewed Ramos in June 2018 about his purchase of a large number of guns over a short period, Ramos was unable to account for nine of the 16 guns, first claiming that he had sold the missing guns and later claiming that some of the guns had been stolen,” investigators said.

During the interview, Ramos said three of the guns were stolen in 2017 but he was afraid to call the police, records show. He claimed he sold some of the guns including a sale to “some guy he met online.”

When police searched the residence, a shotgun was found leaning against a wall, unsecured, according to federal records. A rifle, also unsecured, was found under a bed. Some of the guns were in a locked box.

Investigators said two more guns were unsecured in Ramos’ car.

Ramos, according to federal records, agreed his brother was a gang member, although the specific gang is not mentioned.

“Although Ramos told investigators that people ‘ask him for guns all the time,’ and agreed that his brother was a gang member, Ramos denied that his brother or any other gang member had asked Ramos to buy the firearms for them or had asked to ‘borrow’ the firearms from Ramos,” the ATF agent wrote.
