WALTHAM — An 18-year-old man has been charged in connection with the suspicious death of a woman in her 30s, whose body was found in a residence early Saturday morning, according to the office of Middlesex District Attorney Marian Ryan.
Waltham police responded to a report of an assault on a woman in an Adams Street house at about 2:40 a.m. When officers entered, they found the woman dead, prosecutors said in a statement.
Derrick Lopez of Waltham was taken into custody in connection with the death, and charged with assault and battery causing serious bodily injury, as well as armed assault with intent to murder, according to the statement.
“This is not believed to be a random incident and there is no danger to the public,” said the statement.
The woman’s death is being investigated by the Middlesex District Attorney’s office, the Massachusetts State Police and Waltham police. The state medical examiner’s office will determine the cause and manner of death, the statement said.
Waltham police referred a request for comment Saturday to the district attorney. Elizabeth Vlock , a spokeswoman for Ryan, declined to comment beyond the statement.
No further information will be released pending notification of the woman’s next of kin and the medical examiner’s ruling, the statement said.
Two plainclothes police officers wearing badges knocked on the door of the boarding house at 20-22 Adams St. around 1:40 p.m. Saturday. After a brief delay, they were allowed in by a man.
A few minutes after police entered, another man emerged and walked to a car across the street. He declined to comment.
Police at the scene declined to comment when they left at about 2:15 p.m.
The building, which is listed in Waltham city assessing records as an 18-unit boarding house, is owned by Martin-Reilly Realty of Bacon Street in Waltham.
The state’s corporate database lists James C. Martorilli of Waltham as the sole officer of the organization. He could not be reached for comment Saturday.
One resident of the property said he was startled when police arrived early in the morning.
Ziggy Lycus, 52, said he was getting ready for work at 3 a.m. when he heard pounding outside.
He looked outside, and three police officers ordered him to open the door, he said.
“They were about the kick the door in,” he said.
The officers ran upstairs, and within minutes, additional officers arrived on the scene, Lycus said.
He said he did not hear any commotion before officers arrived. He does not know the suspect or victim, and did not learn of the death until he went to his job as a cook at a restaurant, he said.
Since he’s lived there, most of the tenants have been men in their 50s, who generally keep to themselves.
“I just think it is a fluke,” Lycus said. “In the three years I’ve been here, there’s never been a problem,” said Lycus.
But Susana Dorley, who has lived across the street for eight years, said there has been a repeated police presence at the property.
She has heard men and women arguing there, and has contacted city officials about her concerns, Dorley said.
On Saturday, she woke up to find detectives searching the bushes near her home, and learned of the death from news reports.
“I wasn’t surprised,” Dorley said. “It was bound to happen.”John Hilliard can be reached at firstname.lastname@example.org.
