Rosanna Camilo’s former neighbor, now charged with her rape and murder, left his DNA at the crime scene and beneath her fingernails when he sexually assaulted and strangled her to death in November, Suffolk County District Attorney Daniel F. Conley’s office said today.

ELDRICK D. BROOM (D.O.B. 4/7/84) was arraigned today in Suffolk Superior Court on charges of first-degree murder and aggravated rape. Assistant District Attorney Gretchen Lundgren of Conley’s Homicide Unit recommended that Broom remain held without bail, as he had been since his district court arraignment last year; Clerk Magistrate Gary D. Wilson granted that request.

Lundgren told the court that Camilo, 34, was “a wife and devoted mother of three” who had come to Boston from the Dominican Republic to seek medical care for her 17-month-old son when she was raped and murdered in her temporary residence on Fairlawn Avenue.

Camilo’s 16-year-old daughter, who had come to assist with the boy’s care, was at school in the early afternoon of Nov. 21, 2011, when Broom allegedly gained access to their apartment, raped Camilo, and strangled her to death.

Camilo’s killer “used so much force that he crushed her larynx,” Lundgren said.

“The defendant was known to Ms. Camilo strictly as a neighbor,” the prosecutor said, noting that Broom had lived across the hall from Camilo and her family until late October, when he moved to a different apartment within the same complex.

Lundgren told the court that Boston Police homicide detectives investigating Camilo’s homicide met with Broom shortly after her death. Broom allegedly told them that he had seen her around the complex but had never spoken to her. Detectives took a voluntary buccal swab from Broom at that time.

“In early December, after the DNA swabs from the rape kit and from under Ms. Camilo’s fingernails had been analyzed, Boston Police criminalists determined that the defendant’s complete DNA profile was present on the swabs from the rape kit and that the defendant’s partial DNA profile was present on the swabs from under Ms. Camilo’s fingernails,” Lundgren said. “No other individual’s DNA was present on these swabs.”

Broom “dramatically” changed his story in a subsequent interview with detectives, Lundgren said, and concocted a story in which he said he had several intimate encounters with her, including one the night before she died.

“The investigation reveals that his story was completely fabricated,” Lundgren said, calling the statement “a desperate attempt to mislead detectives.”

At the time of the incident, Broom was free on his own recognizance after allegedly assaulting his girlfriend on Aug. 8. Conley’s office had asked for $2500 cash bail in that case. He has an additional case out of Brookline in which he is charged with open and gross lewdness.

Katherine Moran is the DA’s assigned victim-witness advocate. Broom is represented by attorney Norman Zalkind. He is due back in court on April 5.
