WEST BROOKFIELD — A mother and three children found dead Thursday in their home were murdered, Worcester District Attorney Joseph D. Early Jr. said Saturday.

Early, in describing the deaths as homicides for the first time, asked the public to help investigators locate a yellow plastic fuel can that they believe was taken from the Old Warren Road residence. He declined to elaborate on the significance of the can or say how the victims died.

“We need to speak to anyone who may come across a discarded yellow fuel can,’’ Early said during a news conference near the residence. His spokesman said such cans are commonly used to store diesel fuel.
