VENTURA, Calif. - Following an extensive cold case review, the Ventura Police Department on Friday announced it has named a suspect as the sole person responsible in the 2016 slaying of Arnold Ikeda.
What we know:
On March 20, 2016, Arnold Ikeda was found deceased from a gunshot wound in his home on South Evergreen Drive.
While detectives identified Johnny Caro, also known as "Lieutenant" or "Lou," as the primary suspect early on, there was not enough evidence at the time to file formal charges.
The investigation was suspended after Caro himself was killed in an unsolved homicide in Desert Hot Springs in late 2021.
What they're saying:
Ventura Police Investigations Commander Ryan Weeks emphasized that the department never stopped seeking answers for the Ikeda family.
"This case has never been forgotten," said Weeks. "Our detectives worked it extensively from the start, and years later, the DA’s Office took a deeper look through a cold case review. While this case will not proceed through the criminal justice system, we recognize the impact on Arnold Ikeda’s family and hope these findings provide some long-awaited answers."
