King County’s Major Crimes Detectives are investigating the death of the young man whose body was found in the Green River Tuesday afternoon as a homicide.

The King County Medical Examiner identified the victim Thursday afternoon as 16-year-old Juan Carlos Con-Guzman, and the cause of his death as multiple blunt-and-sharp-force injuries.

Con-Guzman had just started his junior year at Mt. Rainier High School in Des Moines.

According to KCSO spokesman Ryan Abbott, two fisherman were walking along the bank of the river that morning in the 12700 block southeast of Green Valley Road when they saw a body in the water and called 911. The King County Sheriff’s Office Marine Unit recovered the body later that afternoon.

Abbott said Con Guzman’s family had filed a missing person report at some point before he was found in the river, though the KCSO has not released information as to when that happened or how long he had been in the water.

The Auburn Reporter will update this story as it develops.
