The separate killings were the city's ninth and 10th homicides of the year.

In August 2021, the case was assigned to a San José Police Department and District Attorney's Office Cold Case team which brought new life to the investigation.

San Jose police entered the downtown apartment and found the victim’s body in a bathtub. He had been stabbed and had a rope around his torso.

San Jose police have not yet identified the homicide victim, and did not identify Ishihara until today’s announcement on Twitter. The press release gave no further details about the incident, the victim or the alleged assailant.

A man stabbed in East San Jose early today later died of his injuries, the city's 21st homicide victim of 2021. The victim was not identified, and no arrest was reported as of 10pm.
