Jurors in the Mattapan massacre trial were told today that 12 shots were fired at 1:11 a.m. on Sept. 28, 2010, at the intersections of Wildwood and Woolson streets—and more rang out near 76 Wildwood St.

Then jurors heard the gunfire themselves, chilling sounds that meant that two men, along with a young mother and her 2-year-old child, were being slain, while another man was shot in the head and left for dead.

In all, the jury was told, a total of 14 shots were fired during the massacre. The first wave totaled 12 shots and was followed 70 seconds later by a single gunshot; 24 more seconds passed before the 14th, and final shot, was fired.

After several days of powerful testimony from key witnesses in Suffolk Superior Court, prosecutors in the first-degree murder trial of Dwayne Moore and Edward Washington have begun presenting the evidence collected by authorities since the crime that rocked the city.

The two defendants have pleaded not guilty and their attorneys have told jurors they are wrongly accused.

An expert on the ShotSpotter system, which tracks and records the sounds of gunfire, today described what the system detected the night of the brutal crime. The system recorded the first sound of gunfire at 1:11 a.m.; the last sound was recorded 24 seconds later, said Paul Greene, lead forensic analyst for Mountain View, Calif.-based SST Inc., which makes the system.

Jurors were also shown graphic crime scene photographs of the victims: Simba Martin, 21; his girlfriend, Eyanna Flonory and her 2-year-old son, Amanihotep Smith; and Levaughn Washum-Garrison, 22, who was sleeping on Martin’s couch that night. The survivor, Marcus Hurd, is expected to testify later in the trial.

The images were displayed on a large television monitor in the courtroom, leaving many relatives of the victims in tears.

On Tuesday, the mother of the key witness told jurors she did not feel safe testifying, despite an agreement she made with prosecutors to pay for her move from her long-time Boston home under the state’s witness protection program.

Charlene Washington bristled when defense lawyers asked her about the housing benefits she received as a witness in the homicide case against two men in the 2010 crime.

“This means nothing to me because we’re not in protective custody,’’ she said of the agreement. “I don’t feel like I’m being protected.’’

Washington’s son, Kimani, has testified that he helped the defendants rob the victims, but left before the shootings.

Charlene Washington was called to testify against her nephew, 32-year-old Edward Washington, who prosecutors say drove to the crime scene that night and obtained one of the weapons used in the robbery.
