Homicide investigation launched into 3-year-old boy's death

PARKLAND, Wash. -- Detectives have launched a homicide investigation into the death of a 3-year-old boy.

Zebidah Pluff was found dead inside of a Parkland home last week. Family members initially said the boy had gotten sick, but investigators later grew suspicious.

"Our detectives out there looked around and determined things didn't add up," said Det. Ed Troyer. "So we worked it as a regular death investigation, homicide, and unfortunately it was confirmed by the medical examiner's office that it was, in fact, a homicide."

But detectives have not said what specific types of injuries would have caused his death. They said he was found in the morning, and he could have died the night before. They believe his death and injuries might not have happened at the same time.

"The injuries could have happened a couple days before," Troyer said. "So we have to narrow that down and then do a time line and figure out everywhere he'd been and who he'd been around and who can be responsible for this."

Detectives are interviewing a group of people, including the boy's mother, family and friends.

The 3-year-old had other siblings who lived at the house, investigators said, and the boy was a member of the Puyallup Tribe.

His family members held his funeral at Chief Leschi School near Puyallup on Wednesday afternoon.
