A summer road trip ended in tragedy for a Kirkland family when a 10-year-old girl with Type 1 diabetes died on the way back to Western Washington, and her mother was later arrested on suspicion of first-degree manslaughter. Detectives say the child slipped into a coma during the trip and was pronounced dead after being brought to Mary Bridge Children’s Hospital in Tacoma. The mother, identified in court documents as Lloydina Shnea McAllister, remains in custody and has pleaded not guilty.
According to a news release from the Kirkland Police Department, the investigation began on July 24 after a referral from Child Protective Services. Kirkland detectives say they worked with medical staff and the King County Prosecutor’s Office throughout the case. The department reports that McAllister was arrested on Nov. 4 and is being held at the King County Correctional Facility on $1 million bail.
Details In Charging Papers
Local reporting that reviewed the charging documents says the girl’s insulin pump began showing a "high" reading around 10 a.m. on July 16 and that the alarm stayed at its maximum alert level for nearly two days as her condition worsened. As reported by KING 5, the child arrived at Mary Bridge already deceased, and hospital staff recorded a post-mortem blood-glucose level of about 700 mg/dL, which prosecutors say is consistent with prolonged, untreated diabetic ketoacidosis (DKA).
Route, Missed Stops And Emergency Calls
Court documents say cell-phone records show the family drove more than 700 miles south toward the Sacramento area before turning back toward Tacoma, passing numerous open hospitals along Interstate 5 without stopping. As reported by ABC News, detectives found no record of 911 calls during the roughly nine-hour return trip, and filings say the girl’s body showed signs consistent with having been deceased for several hours while still inside the vehicle.
Prosecutors Say Prior Warnings Were Missed
The charging documents, according to local reporting, describe a years-long pattern of missed medical appointments, multiple hospitalizations related to diabetes, and earlier contacts with Child Protective Services. They also state that McAllister received formal retraining on how to use the insulin pump in May. KING 5 reviewed those filings, and the Kirkland Police Department called it "a complex and emotionally challenging investigation" in its public statement.
Legal Next Steps
McAllister has pleaded not guilty, and court records, as covered by ABC News, show a trial date set for late December. Prosecutors are asking for $1 million bail and no-contact orders involving McAllister’s two surviving children. They say that if she is convicted of first-degree manslaughter, the sentencing range could include years in prison.
How DKA Escalates And Why Time Matters
Medical guidance and public-health reports describe diabetic ketoacidosis as a fast-moving, life-threatening complication that can develop within hours when insulin is missing or not working properly. Symptoms such as persistent vomiting, very high blood sugar and rising ketone readings are treated as red-flag warnings that require immediate medical attention. Public health information notes DKA is considered an acute emergency that typically needs urgent hospital care. The CDC reports that DKA is more common in younger people with Type 1 diabetes and can be fatal if it goes untreated.
Investigators say they are waiting on the next steps in the court process while the Pierce County medical examiner completes any remaining examinations. The case continues to be handled by Kirkland detectives and the King County Prosecutor’s Office, as the community and medical providers grapple with the outcome of the girl’s death.
