10-Year-Old Girl Slipped into Fatal Diabetic Coma and Died on Family Road Trip. Her Mother Has Now Been Arrested and Charged By Kimberlee Speakman

A Washington woman has been arrested and charged in connection with the death of her 10-year-old daughter. 

The Kirkland Police Department (KPD) shared in a news release on Friday, Nov. 21, that a 42-year-old woman from Kirkland, Wash. — who was later identified as Lloydina McAllister by court filings, per ABC News — was arrested on Nov. 4 following “an extensive investigation into the death of her 10-year-old daughter.”

Police said the case was highlighted to them by Child Protective Services in July 2025 after the woman brought her deceased daughter to a hospital in Tacoma, Wash.

An investigation found that the woman’s daughter had Type 1 diabetes and was believed to have died from “prolonged diabetic ketoacidosis” — a life-threatening medical emergency that can happen after a person doesn’t receive enough insulin, per Mayo Clinic.

KPD said the child had “slipped into a coma and died” and, through their investigation, determined that “the mother did not obtain medical treatment for the child despite being aware of the child’s symptoms.” Police said their investigation concluded that “the lack of medical intervention contributed to the child’s death.”

The KPD and King County Prosecutor’s Office did not immediately respond to PEOPLE’s request for comment or documents related to the incident.

According to probable cause documents obtained by local outlets, The Seattle Times, KOMO News and KING 5, prosecutors allege that McAllister, her boyfriend, and three kids embarked on a road trip to the Oregon-California border despite her daughter already showing signs of diabetic ketoacidosis. 

The child showed signs of diabetic ketoacidosis prior to the trip, with her insulin pump registering high blood sugar levels, and she started vomiting shortly before the road trip, per the probable cause documents.

Prosecutors claimed the mother should have known that she was in danger due to prior training. Her daughter’s condition continued to worsen as they embarked on the road trip, the probable cause documents say.

The documents allege that the mother drove 714 miles and passed 31 hospitals as the child slipped into a coma and died in the backseat of the car next to her siblings. She had been dead for several hours before McAllister brought her daughter to Mary Bridge Children’s Hospital on July 18, according to the documents.

McAllister reportedly told police that she did not immediately seek medical attention for her 10-year-old, citing a parenting agreement with the girl’s father that didn’t allow her to take the child out of state, per The Seattle Times. She also claimed to investigators that it was the girl’s responsibility to bring her own “life-saving kit,” per the outlets.

According to the affidavit, this isn’t the first time this has happened. The girl was allegedly hospitalized four times for diabetic ketoacidosis before her death since being diagnosed with Type-1 diabetes in February 2018, The Seattle Times reported.

KPD Police Chief Mike St. Jean said in a statement that the case “was a complex and emotionally challenging investigation” and that the KPD remains “committed to protecting our community’s most vulnerable residents, especially children who cannot advocate for themselves.”

McAllister was charged with suspicion of manslaughter in the first degree, according to police. She pleaded not guilty to the charge in King County Superior Court on Nov. 13.
