PUYALLUP, Wash. — More than a year after 5-year-old Brentlee Lawrence died of acute fentanyl toxicity, Pierce County detectives are searching for his father, Kyler Lawrence, who is charged with first-degree manslaughter. Charging documents filed last month say Brentlee’s mother, Jordan Shank, initially told investigators she did not know where Lawrence was. She has since told detectives that Lawrence was hiding in the attic of the Puyallup home where the child overdosed and instructed her to lie, according to the documents. A detective report says investigators have leads on Lawrence’s possible whereabouts. The Pierce County Sheriff’s Office is asking anyone who has seen him or knows where he is to call 911. Brentlee’s relatives say they want both parents held accountable. His uncle, Cody Parsons, said the family is troubled by the timing of the new information, with Shank scheduled for a trial-readiness hearing Oct. 30. Parsons suggested she may be seeking a plea deal, but said he was unsure. The Parsons family cared for Brentlee for nearly a year before a court order under Washington’s Keeping Families Together Act returned him to his biological parents, Shank and Lawrence. Brentlee’s aunt Cassandra Parsons questioned why drug testing did not continue after the child was returned. Her remarks reflect the family’s concerns; the case documents described in the charging allegations do not establish those broader claims. Another aunt, who was not identified, said in a statement that she had repeatedly contacted Child Protective Services and alleged Brentlee endured years of abuse. Those claims have not been established in court. Lawrence’s charge is an allegation, and he is presumed innocent unless proven guilty. Anyone with information about his location should call 911, the sheriff’s office said.
