Family grieves for slain sisters

Two young sisters killed in an Easter Sunday tragedy will be forever loved and missed, their grieving family says.

The girls, Savannah, four, and Indianna, three, were found dead at their Melbourne home, and a man known to them was arrested at the scene on Sunday afternoon.

The 35-year-old has since been charged with their murder.

The girls' family say they are shattered by their loss.

"We are utterly devastated at the loss of Savannah and Indianna," the family said in a statement released by Victoria Police on their behalf.

"The girls will be forever missed, loved and never forgotten."

The family asked that their privacy be respected to allow time to grieve.

Police issued a statement early on Monday saying Charles Mihayo, of Watsonia, has been charged with the murder of both girls and remanded in custody to appear at the Melbourne Magistrates Court on Tuesday.

Police are yet to reveal how the children died or give details of any injuries.

A number of family members were at the home at the time the incident unfolded.
