ARIZONA: Police say a woman threatened to stab her husband over an argument about money to move to Japan before she allegedly killed their two children with a meat cleaver in a suburban Phoenix apartment.

Tempe police say 40-year-old Yui Inoue remains jailed on suspicion of two counts of first-degree murder.

It was unclear Sunday if Inoue has a lawyer yet.

Police said the woman primarily speaks Japanese and had an interpreter for their interviews.

Authorities say Inoue drove to a police station about 7 a.m. Saturday and told officers she was hearing voices telling her to kill her children.

Police say a 7-year-old boy and a 9-year-old girl were found dead in the apartment.

Their names weren't immediately released.
