Child, 12, Dies Of Heroin Overdose, Joliet Mom Lands In Will County Jail For 2024 Death: Prosecutors

JOLIET, IL — Back in 2024, Joliet Patch broke the news surrounding the death of 12-year-old Mya King, who died from a heroin ingestion. At the time, although Joliet police arrested her mother on a charge of possession of a controlled substance, she was released from the Joliet police custody and prosecution did not move forward at that time.

Now it is.

Over the weekend, Will County Jail logs show that the Joliet Police Department arrested 37-year-old Colette Bancroft and the criminal charges appear to link her to the death of her 12-year-old daughter. The jail logs list her charges as being involuntary manslaughter, child endangerment involving a death and two counts of possession of controlled substances. The jail lists the dates of the offense as being April 14, 2024, which lines up with the time for Mya King's death.

Bancroft is listed as being on the court calendar for the Monday morning call in Courtroom 405 which often numbers 40 to 50 defendants on a Monday.

More than two and a half years ago, Joliet police spokesman Dwayne English told Patch that at around 8:24 a.m. on a Sunday, Joliet police went to the house in the 1500 block of East Washington Street for an unresponsive juvenile. Officers found the 12-year-old girl in the bedroom on the second floor.

Officers immediately provided medical assistance, including CPR and the deployment of Narcan, until the arrival of Joliet Fire Department paramedics.

It was believed that the 12-year-old victim ingested an unknown amount of suspected heroin and fentanyl, English said at the time.

The victim was originally discovered to be unresponsive by her mother, Bancroft, and others in the home called 911. Officers said that Bancroft and her daughter shared the bedroom where the victim was found. The Joliet police recovered suspected heroin and fentanyl from Bancroft’s purse in the bedroom, and she was placed into custody without incident, according to English.

The 12-year-old victim was rushed to Silver Cross Hospital by the Joliet Fire Department. Shortly thereafter, she was transferred to Ann and Robert Lurie Children’s Hospital of Chicago, where she died shortly after 5 p.m. three days later, according to police.

"This case remains under active investigation as detectives and evidence technicians continue to process information and evidence pertinent to this case," English remarked in 2024.

Bancroft's jail mugshot now lists her address as being in Lockport in the 14500 block of Archer Avenue.

Back in 2024, Joliet Patch reported that Melissa King, Mya's aunt who lives in Lockport, was organizing the GoFundMe.

"Baby girl was only 12. This was so unexpected and devastating to the family," King posted. "I don't want to go to much into details, but it was an overdose off heroin mixed with fentanyl. Why is still the question. Was it an accident was it on purpose, we will never know!! but what I do know is she was always full of life around us. "
