NBC 7 has learned the identities of the three women who were found dead inside a home in Rancho Santa Fe earlier this week.
Sayeh Amini, 48, was identified by her family’s attorney on Thursday. Amini was the sister of homeowner Michael Arya, who had lived there prior to his death from cancer in April.
“It’s just a horrible situation," said attorney Carl Starrett.
Deputies responded to reports of a possible child abuse inside a home on 17100 block of Villa De La Valle on Monday morning. When they arrived, they found the bodies of two women and a female teenager.
The San Diego Sheriff's Deparent isn't confirming Amini's identity.
But a Mercedes registered to her sat in the driveway during the homicide investigation in front of the home.
"Her brother appointed her to be manager of affairs after he passed," explained Starrett.
Starret had known Amini for at least 10 years and her husband longer. He says the responsibility of handling her deceased brother's estate became overwhelming.
“She seems to have had some mental health challenges she wasn't able to overcome. Twice in a week prior to the tragedy, her husband sought help for his wife and when she was suicidal.”
Family and friends have confirmed Amini's niece, 15-year-old Hannah Arya was one of the deceased.
The teen is described as a smart young lady who had been in town from Oregon, visiting friends and her father’s home.
The other woman found dead was Mia Shin, a close friend of the Arya family.
Shin's brother told NBC 7, she was a real estate broker in Los Angeles but was in town working on some deals.
Investigators haven't released a cause of death or motive at this time.
But they saying they're not searching for a suspect and believe this incident to be a murder-suicide.
Investigators say they plan to release new information Friday morning.
