Koan Camino Yarter was three months old when he died in Denver, Colorado, on October 17, 2012. Public memorial records list his birthdate as July 19, 2012, and note visitation at a Lakewood chapel on October 23 with burial at Crown Hill in Wheat Ridge the following day. Those notices document the family’s arrangements but do not explain the circumstances of his death.

No mainstream press accounts or law-enforcement bulletins publicly name a suspect or report an arrest in connection with Koan’s death. Cold-case portals for Denver and the Colorado Bureau of Investigation do not show an entry under his name, and community listings describe the case as unresolved.

If anyone knew Koan or has information that could fill in these unanswered details, please share what is known with investigators.
