A woman and her parents were served fresh arrest warrants on Monday for allegedly murdering a man who was found decapitated in a hotel in Sapporo last month, according to local police.
Runa Tamura, 29, and her father, Osamu, a 59-year-old psychiatrist, were first arrested on July 24 on suspicion of mutilating and abandoning a corpse. Runa's mother, Hiroko, 60, was arrested the next day on the same charges.
The victim, identified as Hitoshi Ura, 62, was found naked and decapitated in a hotel in the Susukino entertainment district on July 2. An autopsy revealed that the cause of death was hemorrhagic shock caused by blood loss.
The police subsequently discovered the severed head at the Tamura residence, suspecting it was cut off after Ura died.
Ura checked into the hotel at around 10:50 p.m. on July 1 with an individual believed to be Runa Tamura. The individual was then seen leaving the hotel alone at about 2 a.m. the following day, according to the police.
Runa Tamura is believed to have been the only one at the crime scene, but the police suspect her parents were accomplices.
