A 12-month-old in St. Peters had to be revived with Narcan on Tuesday after what investigators describe as an apparent fentanyl overdose, and a local man is now facing federal charges. Prosecutors say first responders and hospital staff moved fast enough to save the child, and a second infant was later treated for exposure. Authorities report that firearms, bulk cash and what they call a large quantity of raw fentanyl were recovered in connection with the suspect’s vehicle.
Charges and what investigators say
Federal prosecutors have charged 50-year-old Kevin Lamar Knowles with one count of possession with intent to distribute fentanyl, one count of being a felon in possession of a firearm and one count of possession of a firearm in furtherance of a drug trafficking crime, according to First Alert 4. Prosecutors say Knowles was arrested Wednesday and appeared in court Thursday. Court filings cited by the outlet state that emergency responders were called to a St. Peters home on Tuesday, where a 12-month-old was found suffering an apparent overdose; the child received Narcan and was taken to a hospital for treatment.
Officials praise lifesaving response
In a statement to First Alert 4, U.S. Attorney Thomas C. Albus said, “This case is more proof that fentanyl is poison and should be treated as such.” St. Peters Police Chief Andrew Ramirez credited the quick work of the ambulance district and patrol officers for saving lives and helping lead to the seizure of what prosecutors describe as 1.5 pounds of raw fentanyl. Drug Enforcement Administration St. Louis Field Division assistant special agent in charge Colin Dickey warned that “fentanyl, even amounts small enough to fit on the tip of a pencil, can be life threatening.”
How this fits a wider pattern
A nationwide review by Scripps News examined more than 260 fentanyl overdoses involving babies and young children and found that roughly half of the cases involved families already known to police or child-welfare workers. The investigation includes multiple Missouri incidents, and experts interviewed for the report urged wider naloxone access and earlier intervention to protect children. Public-health researchers cited in the review note that pediatric fentanyl poisonings can be sudden and require immediate treatment.
St. Charles County response
St. Charles County officials say accidental overdose deaths have dropped from 2023 highs, but fentanyl is still the leading cause of overdose fatalities locally. The county is expanding public Narcan access and operating prevention and recovery programs. County reports show overdose deaths last year occurred across the county, including in St. Peters, and officials point to school outreach and drug-treatment court programs as part of their prevention work. Local authorities have also emphasized cooperation with federal agencies in the investigation and seizure tied to this case.
What happens next
Knowles now faces federal prosecution in the U.S. Attorney’s Office. The charges are allegations, and he is presumed innocent unless and until proven guilty. If convicted on the federal drug-trafficking and firearms counts, defendants in such cases commonly face significant prison terms, though any penalty would depend on the outcome of the case and federal sentencing guidelines. Prosecutors and detectives say the investigation is ongoing and have not released additional court dates or bond information.
Why authorities say parents should be vigilant
Officials say this case highlights how even small amounts of fentanyl can be deadly to children and urge caregivers to secure all medications and illicit substances. They recommend keeping naloxone available where appropriate, reporting suspicious activity, training family members in how to use naloxone, and reaching out to local prevention resources if substance use is a concern around children. Anyone with information about the investigation is asked to contact St. Peters police or federal authorities.
