A man arrested Wednesday moments after police said he participated in a deadly home invasion in Dorchester pleaded not guilty Thursday to charges of unlawful possession of a firearm.
Cedrick Slayden, 18, was also charged in Dorchester Municipal Court with illegal possession of ammunition and carrying a loaded firearm, charges that stem from his arrest on Esmond Street as police responded to investigate a shooting.
Police allege that Slayden, of Roxbury, and another man, both masked, forced their way into a unit inside 85 Esmond St. shortly after 9 a.m. Wednesday. A resident of the apartment, however, opened fire with his own weapon, fatally injuring Slayden’s associate, police said.
As police flowed into the neighborhood after a series of 911 calls, officers spotted Slayden near the intersection of Harvard and Bicknell streets “breathing heavily and sweating despite the cool temperature,’’ police said in a report.
As officers approached him, police said, they saw him pull an object out of his pants and throw it into an adjacent yard. Police later recovered a black and silver Smith & Wesson 9mm handgun with six rounds in the magazine and one round in the chamber, they ssaid.
Police and Suffolk District Attorney Daniel F. Conley’s office continue to investigate the fatal shooting and have not released the name of the person who was fatally shot or the name of the Esmond Street resident who shot him.
In court, Judge James Coffey set bail at $50,000 cash for Slayden and revoked bail from an unrelated charge. According to prosecutors, Slayden was free on $1,000 bail on charges of stealing a man’s iPhone in the North End last May 29.
