A 22-year-old Federal Way man is facing a second-degree manslaughter charge after prosecutors say he left his swaddled 4-month-old son face down on a Boppy pillow inside an apartment, where the baby suffocated. Elijah Jamal Pendleton Brown is scheduled to be arraigned at 9 a.m. on September 9 in a courtroom at the Maleng Regional Justice Center in Kent, and he has remained in custody at the King County Correctional Facility in Seattle with bail set at $450,000.
According to charging documents cited by Seattle Weekly, the case dates back to February 24, when Federal Way police responded to the Crestwood West Apartments on Pacific Highway South at about 1:01 p.m. after the baby's mother called 911 reporting that CPR was already underway. The first officer on scene found the baby lying unresponsive on the apartment floor and began lifesaving measures, which South King Fire medics then took over. The lifesaving efforts were unsuccessful, and the baby was declared deceased at about 1:29 p.m. South King Fire personnel believed the infant had likely been dead for at least 30 minutes before they arrived.
Officers also found Brown hiding inside a brown Lexus near the apartment building and took him into custody, not initially for the infant's death, but for violating a domestic violence no-contact order. That order, issued by Federal Way Municipal Court in September 2025 and not set to expire until September 2030, named Brown as the restrained person and the baby's mother as the protected person, barring him from coming within 1,000 feet of her or her residence.
What Brown Told Detectives
During a detective interview, Brown said he left the apartment because he knew he had violated the no-contact order, and he told investigators he primarily cared for the baby, including feeding him and changing his diaper. Brown said he attempted CPR after finding the infant unresponsive. But according to the charging documents, he also told detectives he had placed the baby in a swaddle with his arms cinched to his sides and set him face down in a sleeping device that senior deputy prosecuting attorney Jocelyn Cooney described in charging papers as akin to a straitjacket, then walked away.
The King County Medical Examiner's Office ruled that the baby died of asphyxia due to obstruction of the external airway and classified the manner of death as an accident. Per the charging documents, Cooney wrote that the defendant kept his child face down with no ability to push himself up, and that Brown's failure to recognize a substantial risk to the baby was a gross deviation from reasonable care. Cooney also wrote that a competent parent would not leave a 4-month-old baby unattended unless the baby was in a safe and secure location, noting in her filing that Brown had two separate pack and plays available in the apartment.
Why It Took Six Months to File Charges
Charging documents were filed on August 27, roughly six months after the infant's death, and the delay traces back to forensic testing. Prosecutors were waiting on DNA results from the Washington State Toxicology Lab to corroborate Brown's own statements about placing the baby on the Boppy pillow before proceeding with the manslaughter charge; those results ultimately did corroborate his account.
The wait fits a pattern described by state officials. As KING 5 News reported in May, Washington State Patrol officials said the state toxicology lab was managing a backlog of more than 15,700 cases, with testing turnaround stretching up to 10 months for alcohol cases and as long as 20 months for cases involving multiple drugs, against a stated lab goal of delivering results within 60 to 90 days. Lawmakers responded in March by enacting Senate Bill 5880, which, as KOMO News reported, allows cities and counties to contract with accredited private toxicology labs to help clear the backlog after long delays raised concerns about statutes of limitations in pending cases statewide.
The Legal Standard Prosecutors Must Meet
Brown is charged under RCW 9A.32.070, which defines second-degree manslaughter as causing a death through criminal negligence and classifies it as a Class B felony. Under RCW 9A.20.021, that carries a maximum penalty of up to 10 years in state prison and a fine of up to $20,000, though standard state sentencing guidelines for a defendant with no prior criminal history typically call for a range of 21 to 27 months if convicted.
Prosecutors do not need to prove Brown intended to harm his son. Washington law, under RCW 9A.08.010(1)(d), defines criminal negligence as failing to be aware of a substantial risk that a wrongful act may occur when that failure is a gross deviation from the standard of care a reasonable person would exercise in the same situation — the lowest of the state's four culpable mental states. Separately, the initial no-contact order violation that landed Brown in custody outside the apartment is typically charged in Washington as a gross misdemeanor under RCW 7.105.450, punishable by up to 364 days in jail and a $5,000 fine, though it can escalate to a Class C felony carrying up to five years in prison if reckless endangerment or prior violations are involved.
A Known Suffocation Hazard
The pillow at the center of the case has a documented federal safety history. The Consumer Product Safety Commission and the Boppy Company recalled more than 3.3 million Boppy Newborn Loungers in September 2021 after eight infant suffocation deaths, and the CPSC re-issued urgent safety warnings in June 2023 following two more infant deaths tied to the product. Federal regulators have also moved more broadly against soft, inclined infant sleep products: the Safe Sleep for Babies Act, enacted in 2022 and codified by the CPSC in 2023, banned the manufacture, distribution, and sale of inclined infant sleepers and padded crib bumpers for babies up to one year old.
Medical guidance underscores why placement matters so much for swaddled infants. According to Safe Sleep Academy guidance reflecting American Academy of Pediatrics consensus, swaddled babies placed face down face a heightened suffocation risk because the swaddle restricts upper-body movement, preventing them from turning their heads or pushing up to clear their airway; pediatric guidance recommends stopping swaddling once an infant starts trying to roll over. Nationally, the Centers for Disease Control and Prevention estimates that roughly 3,500 infants die unexpectedly each year in the United States from sleep-related causes, including accidental suffocation, position-related asphyxia, and SIDS.
Brown's case is not the first infant-safety matter to draw attention in South King County in recent years. Hoodline previously reported on a Federal Way kidnapping involving a 7-month-old, and separately covered a fatal infant fentanyl exposure case out of neighboring Des Moines. Brown's arraignment at the Maleng Regional Justice Center — the South King County venue for felony proceedings, named for longtime King County Prosecutor Norm Maleng — is set for next Wednesday.
