Brandy Manville was killed by her husband Charles Manville, who then died by suicide, per police

An Indiana woman who once profusely praised her husband’s support during her cancer treatment was killed by him in a murder-suicide, per police.

Brandy Manville, 46, was fatally shot by husband Charles Manville, 45, in their Portage, Ind., home during the Thanksgiving holiday, Portage Police Chief Michael Candiano confirms to PEOPLE.

Charles also shot their 21-year-old daughter, who survived the shooting, before turning the gun on himself in the Friday, Nov. 29 attack, the Portage Police Department said in a statement.

Candiano confirms to PEOPLE the daughter called 911 on Friday evening to report a domestic disturbance.

“It was called in initially as a ‘verbal disturbance’ and escalated from there,” Candiano says.

The daughter told the 911 operator that Charles was “intoxicated and throwing items inside the house,” per the statement from Portage police. After he armed himself with a gun, 911 operators could hear him threaten those around him, telling them they were all going to die.

By the time police arrived at the residence, Charles had already opened fire. He and Brandy were found dead and their daughter was transported to a local hospital, per the statement.

Brandy, an administrative assistant at the Portage High School, was a breast cancer survivor, according to a 2019 interview with local outlet Portage Life, where she spoke about the support of her family, including Charles, that was crucial in her recovery.

She said that during the “hell” of her health problems, Charles stood by her. She told the outlet that Charles, who she called “Charlie” during the interview, would repeatedly reassure her and remind her how thankful he was for her presence in his life.

“As a woman, it’s hard to lose your hair,” Manville said in her interview. “Never once did I feel less loved. My family was awesome throughout my cancer journey. I was lucky to have them as a support system.”

It’s unclear what changed for the family in just a few short years. The Friday statement from police said authorities had been unable to get the daughter’s account of what happened, and had not determined a motive.

In a GoFundMe set up for the surviving daughter’s medical costs, Brandy is being remembered as a loving mother with a great sense of humor and an “infectious laugh.”

“She would [want to be known as someone] who would be in the corner ready for a well-timed and hilariously inappropriate one-liner,” reads part of the fundraiser.

She is also remembered for her kindness towards the children at the school where she worked.

“The children that passed in those hallways knew she was an advocate for them and none of them walked away from her hungry or without a smile on their face,” the fundraiser states.
