Vic man in court over girls' murder

A man accused of murdering his two young daughters on Easter Sunday has appeared in court.

Charles Amon Mihayo, 35, has been charged with two counts of murder after Savannah, four, and Indianna, three, were found dead at a Watsonia home on Sunday afternoon.

Mihayo, of Watsonia, briefly appeared in the Melbourne Magistrates Court on Tuesday morning.

He was remanded in custody for a committal mention in August.

Photographs of the smiling sisters, captured in matching outfits and holding hands, were released by the family on Sunday.

Family members say they are devastated by their loss and say the girls will be missed forever.

"We are utterly devastated at the loss of Savannah and Indianna," they said in a statement released by police.

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

Floral tributes and messages of sympathy were left outside the Watsonia home on Monday.

Police have not revealed how the children died.
