Mass. woman killed in murder-suicide left behind a young daughter. Here’s how you can help.

Karine Asatryan, 35, was one of two women authorities say was shot and killed by 31-year-old David Minasvand in their Watertown home late last month. Now, her sister is asking for donations to help support Asatryan’s young daughter, Madeline.

“Tragically, Madeline has now lost both of her parents. She will be lovingly raised by her aunt, Meline, who is stepping into this role with courage, tenderness, and unwavering devotion,” Meline Asatryan wrote on a GoFundMe campaign page.

Watertown police found Karine Asatryan, Minasvand and 80-year-old Nadia Abrahamian shot dead inside the Boyd Street home they shared during a well-being check on the morning of Sunday, Aug. 31, the Middlesex County District Attorney’s Office said previously.

Minasvand is believed to have fatally shot himself after killing the two women, the district attorney’s office said. No one else was at the home at the time.

The district attorney’s office has not specified the relationship between the three individuals or released much information about the killings, but stated previously that Minasvand and Asatryan were living together in the first floor of the home, and that Abrahamian — who was known to them — was living separately on the second floor.

A young mother lost

Meline Asatryan describes her sister in the GoFundMe campaign as “a beloved daughter, devoted mother, and cherished friend.”

“Karine was a bright light in the lives of everyone who knew her,” she wrote. “Her warmth, kindness, and boundless compassion left a lasting impact, and her absence is deeply felt by all who loved her.”

Photos of Madeline posted to the campaign show a bright, smiling, toddler-aged girl with chestnut brown hair.

“Becoming a mother filled her with immense joy and purpose,” Meline Asatryan wrote of her sister. “She embraced motherhood with her whole heart, pouring all her love and hopes into her daughter’s future.”

Donations to the GoFundMe campaign will be used to meet Madeline’s immediate and long-term needs, Meline Asatryan wrote. The money will pay for things such as Madeline’s baby supplies, medical care, childcare and education.

“This fundraiser has been created to honor Karine’s memory and, most importantly, to support baby Madeline as she begins life without her parents,” she wrote. “ … Your generosity will help provide Madeline with the loving, stable foundation that Karine would have wanted for her daughter.”

The campaign had raised a little over $35,000 of its $50,000 goal as of Tuesday evening.

“Karine’s passing is an unimaginable loss. She will be forever remembered for the love she gave so freely, and through Madeline, her beautiful spirit lives on,” her sister wrote.
