Mass. man charged in slayings of mom, wife, kids

WINCHESTER, Mass. (AP) - A man whose wife, two children and mother-in-law were found slain in the family's Massachusetts home has been named a suspect in the killings.

Authorities said Thursday that they have issued an arrest warrant for 43-year-old Thomas Mortimer IV charging him with four counts of murder.

Mortimer remains unaccounted for, a day after 64-year-old Ellen Stone; her 41-year-old daughter, Laura Stone Mortimer; 4-year-old Thomas Mortimer V and 2-year-old Charlotte Mortimer were found dead.

Police say Mortimer may be driving a silver or light gray Toyota Highlander with Massachusetts license plate 81VJ58.

Authorities would not say how the victims died, but District Attorney Gerry Leone described it as a "horrific, disturbing and unspeakable" scene.
