Who killed Keigo Higashino?

The murderer is Runyi. On Friday night, Kawaizumi called her brother and told him that she was in a bad mood and wanted to go back to her hometown to meet her brother and Quan Kangzheng. He and Quan Kangzheng waited for two days without seeing his sister, so they came to her sister's place. By this time, her sister had lost her breath.

The cause of death was electric shock, that is, two wires of the electric blanket, one connected to the chest and the other connected to the back and connected to the timer switch. When the time is up (1), the current passes through the heart and dies instantly.

According to his sister's cleanliness, untidiness in the house, plastic strings in the corner, corks and corkscrews on the floor, and an unlocked door chain, he judged that her sister did not commit suicide, but killed him. So after collecting some evidence, I called the police to avenge my sister.
