Federal Way detectives are investigating the death of a 13-month-old boy.

Police and medics were called out to a report of a CPR in progress at approximately 9:56 a.m. on Sunday in the 35000 block of Eight Ave. SW. However, medics were unable to revive the toddler.

Detectives were also called to the home due to suspicious circumstances and the boy’s age, according to the police report.

Prior to police arriving at the residence, the boy’s father left the home. Police believe he left due to a no-contact order with his current girlfriend who was at the residence, said Cathy Schrock, spokesperson for the Federal Way Police Department. The father was later arrested for violating the domestic violence protection order.

An autopsy later found that there was no evidence of abuse or physical trauma, Schrock said.

However, the boy’s cause of death is still pending further toxicology reports from the King County Medical Examiner’s Office. The investigation is ongoing, awaiting the cause of death.
