An Arizona mother has been charged with first degree murder after officers found her two children stabbed to death in her apartment.

Tempe police said that Yui Inoue, 41, flagged them down at the Apache Boulevard substation at about 7 a.m. Saturday and said she was hearing voices that told her to kill the children, ABC15 said.

Officers went to her nearby apartment and found a 9-year-old girl and a 7-year-old boy dead with “obvious signs of physical trauma,” as CrimeOnline previously reported.

Hours before, police responded to the apartment to a domestic dispute between Inoue and her husband, who have filed for divorce and were sleeping in separate rooms in the apartment. The husband said the couple fought over money for Inoue’s upcoming move to Japan, adding that he left the apartment at about 3 a.m. and slept in his car. He said that while Inoue had threatened to stab him during the argument, prompting the call to police, he had no concerns that she would harm the children, who were asleep in their beds when officers left.

Inoue told police that after her husband left, she went to sleep with the children, waking up at about 4:30 a.m. with blood on her hands and arms. Inoue told detectives she didn’t believe she had harmed the children but could not remember.

Police said they found a possible weapon in a bag inside the vehicle Inoue drove to the police station.
