The ongoing trial for the brutal murder of Richard Field and Lina Bolanos is slowly exposing some of the doctors' final efforts to save themselves.

On the third day of the testimony, jurors listened to a 911 call by Bolanos from the night they were stabbed to death inside their penthouse in South Boston.

The call, however, was muffled and the operator eventually hung up when Bolanos wasn't able to respond to questions, said WCVB.

Despite the condition of the call, Amanda Gibbs, who listened on the witness stand, was still able to recognize the voice of her godchild, according to CBS Boston.

“That was Lina's voice,” Gibbs said when prosecutor John Pappas asked her if she knew who placed the call.

Bolanos, 38, and Field, 49, were stabbed to death in May 5, 2017. Both were well-known anesthesiologists, said CNN.

Like Bolanos, Field also sought help by texting a friend.

Matthias Heindenreich, who testified last week, told CNN in another report that he was “confused for the first minutes” that he received a series of eight text messages.

The messages started “Call 111,” then “Gun man”, “in house” and ended with “Serious,” said the Boston Herald.

“I did not realize what (the text) means, wasn't sure what it is,” he said.

Heindenreich claimed that he replied to the texts but got no answer.

Fabiana Fagundes also told the jury that she received an emergency text message from Field.

She said she immediately contacted the concierge of the building where the couple lived, called 911 and hailed a ride to the penthouse with her boyfriend.

Fagundes added that she heard gunshots when she arrived at the building. WCVB said it was the sound of Bampumim Teixeira being shot by the Boston police after they responded to “multiple 911 calls.”

Prosecutors pointed at Teixeira as the suspect for the murder of Bolanos and Field. Assistant District Attorney John Pappas told the court that Teixeira once worked as a concierge at the building where the victims lived.

“As such, Teixeira was familiar with the interior of the building as well as its parking garage,” the Suffolk County District Attorney said in a 2017 press release.

It added that officers found Bolanos' and Field's bodies in separate areas and that they had been “bound, suffered massive traumatic injuries, and were declared dead at the scene.”

Teixeira was later arrested in the hallway and told officers that there were dead bodies in the penthouse, said Boston police Detective Sean Wallace.

Wallace also pointed that Teixeira said, “You guys are going to die,” and “They killed my wife.”

“Then he mentioned something and I heard the word 'sniper.'”

“He was smiling up at me,” expressed Wallace.

Teixeira was transported to a Boston hospital for treatment and was later arraigned.
