When a 60-year-old grandmother left to visit a relative last week, an apparent murder-suicide unfolded at her California home.

According to the Sacramento Bee, the grandmother received a phone call from her husband's phone around 3 a.m., but it wasn't 60-year-old Richard Thayer on the line.

It was her 4-year-old granddaughter, and she'd just discovered her parents and grandfather dead.

Amador County Sheriff’s Office said in a press release that the girl's father, 26-year-old Jacob Thayer, shot his father and 27-year-old-Marie Ann Leonetti before turning the gun on himself.

The grandmother arrived at the home after receiving her granddaughter's phone call to find all three of her family members dead, WDSU reports.

She then immediately contacted police, who arrived by 3:05 a.m.

The Sacramento Bee reports that Richard Thayer and Leonetti died after sustaining multiple gunshot wounds. Jacob Thayer killed himself with a single gunshot from a Glock .40 caliber pistol registered in his name.

Though the little girl was in the home during the shooting, she did not witness the shootings and didn't sustain any injuries.

Amanda Gold, the young mother's cousin, told WDSU:

“I’m really sad. It’s a really sad thing. But I’m also just in shock, like nobody saw it coming.”

She hopes the little girl will remember the love that her mother had for her. Gold said:

“I hope [the 4-year-old] remembers her mom and how much her mom loved her. If she remembers anything of her mom, I hope it’s that.”

According to a GoFundMe set up by a relative of Leonetti, the family was under financial strain after her father was diagnosed with brain cancer last year.

Leonetti's family is now hoping to raise money for the 4-year-old's college fund.

They have raised over $5,000 as of Monday.
