(KRON) — Two children who died in a suspected murder-suicide in Danville last week have been identified as a 13-year-old and her 11-year-old sister, according to a GoFundMe.

An adult who also died in the incident was previously identified as 44-year-old Nemanja Isailovic, of Danville. The two sisters are believed to have been his children.

The girls, along with their father, were found dead inside their Danville home last Wednesday around 5:20 p.m. when officers arrived to conduct a welfare check.

“Officers entered the residence and found three bodies, an adult and two juveniles,” the Contra Costa County Sheriff’s Office told KRON4.

According to the GoFundMe, the family is asking for help in relieving financial burdens related to funeral expenses and other costs.
