A South Boston man was arrested and charged with shooting a 32-year-old woman to death in Dorchester last February, police said.

Stepheon Wells, 20, was arrested Friday morning by members of the Boston Police Fugitive Unit on a murder warrant out of Dorchester District Court.

Wells is accused of killing Diva Ayuso, of Sharon, on the evening of Saturday, Feb. 18.

He was arraigned on murder and firearms-related charges Friday in Dorchester District Court, and was ordered held without bail, the Suffolk District Attorney’s office said.

Boston Police said Ayuso was shot multiple times in the area of 15 Fermoy Heights in Dorchester, and was pronounced dead at the scene. Officers had responded to a “ShotSpotter activation” at approximately 8:46 p.m., the department said.

“As the officers were looking for ballistic evidence, the officers were notified by a witness that a person was down in the Franklin Hill Green park,” the police report states. “The officers rushed to the victim and rendered aid.”

Ayuso was declared “non-viable” at 9:54 p.m. An autopsy determined her death was caused by “multiple gunshot wounds,” and her manner of death was homicide, the report states.

A search warrant was executed on March 28, and Wells was arrested on a straight warrant on Friday, at 8:04 a.m., the report states.

Wells will return to court on July 31 for a probable cause hearing, the DA’s office said.
