A 33-year-old woman and a 16-year-old boy were arrested Tuesday after police seized multiple narcotics and illegal handguns from a Waterbury apartment.

Police executed a search and seizure warrant at an apartment on Hillview Avenue in Waterbury Tuesday. Police said they found 30 bags of heroin, 7.3 grams of crack cocaine, 21.6 grams of cannabis, 10 pills suspected to be a controlled substance and two loaded 9-millimeter handguns with extended magazines.

Officers arrested 33-year-old Beronica Vicente and a 16-year-old who lived at the home. A 13-year-old girl was also inside the house at the time police executed the warrant.

Vincente was charged with criminal possession of a pistol or revolver, criminal possession of a firearm or ammunition, illegal sale or transfer of a pistol or revolver, two counts of failure to declare high-capacity magazines, possession of narcotics with intent to sell, possession of cannabis with intent to sell, possession of a controlled substance with intent to sell, operation of a drug factory, tampering with evidence and two counts of risk of injury to a minor.

She was previously convicted of a felony and is ineligible to possess a handgun under Connecticut state law.

She posted a $150,000 bond and is pending a court arraignment, police said.

One of the two guns was found to belong to the 16-year-old boy. He was not home at the time of the police raid but was located later by police and arrested. He was charged with failure to declare a high-capacity magazine and illegal sale of a pistol or revolver.

The Department of Children and Families was contacted during the investigation, police said.
