Several hundred mourners packed into Gate of Heaven Catholic church in Boston on Friday to pay their final respects to Lina Bolanos and Richard Field, the engaged doctors who were found slain last week in Field’s luxury penthouse condo.
The crowd was mostly friends, family and colleagues of the couple. The service was closed to the media and the general public.
“It was a very sad morning,” says friend Gina Rand, who attended the memorial, which included several eulogies of the slain couple from close relatives and friends.
“It was just a service to remember these two wonderful people,” Rand tells PEOPLE. “They were loved by many people.”
Bolanos and Field were remembered for their compassionate bedside manner as physicians, their love of adventure and, most of all, the deep love they had for their families and friends.
“You could hear people sniffling through the church,” says Rand. “It was so terrible.”
Bolanos, 38, and Field, her 49-year-old fiancé, were found dead on May 5 in his $1.9 million condo in South Boston. Their throats were slashed and a “message of retribution” was allegedly written in blood on the walls of their home, according to police.

A motive in the killings remains unclear, though the prime suspect, Bampumim Teixeira, allegedly had a black backpack full of Bolanos’s jewelry, according to prosecutors.
Authorities said that Teixeira, 30, was shot multiple times at the scene on Friday night. He was arraigned from his hospital bed on Monday afternoon and is being held without bond. He has been charged with two counts of murder, and authorities say that more charges could be handed down at a later time.
Teixeira’s court-appointed attorney did not return PEOPLE’s call for comment. He has not yet entered a plea.
