Prosecutors say a 40-year-old Oklahoma City man has been indicted in connection with the fatal fentanyl overdose of 29-year-old mother of three Kambri Newsom, Attorney General Gentner F. Drummond announced this week. A multi-county grand jury handed up the indictment naming D.J. Simpson and alleging he distributed the drugs to Newsom in November 2025. The medical examiner ruled her death was caused by fentanyl toxicity, and prosecutors are pursuing a murder case along with drug-distribution charges.
Attorney general's statement
"Drug dealers who prey on people in recovery are committing murder, plain and simple, and justice demands they be held accountable to the fullest extent of the law," Drummond said, per KFOR. According to the attorney general's office, the indictment returned by the multi-county grand jury includes counts of murder in the first degree or, in the alternative, murder in the second degree, along with distribution of a controlled dangerous substance.
Charges and timeline
The AG's announcement states that Simpson is accused of supplying the drugs to Newsom in November 2025 and now faces first-degree murder or, alternatively, second-degree murder and distribution charges, per KFOR. Officials also emphasized that every person who is arrested or charged is presumed innocent until proven guilty in a court of law.
Victim remembered
Newsom is identified in public records and an obituary as Kambri Brooke Cripps. She was 29 and the mother of three children. Her family held services in late November 2025, according to an online obituary posted on Legacy.com.
Legal context
The case lands amid a series of high-profile Oklahoma prosecutions targeting dealers tied to fatal overdoses, as state prosecutors step up efforts to hold sellers criminally responsible. A 2025 conviction resulted in a 20-year sentence for a dealer linked to a fentanyl death, underscoring prosecutors' willingness to pursue homicide charges in overdose cases, as reported in a 20-year sentence in a prior fentanyl death case.
Public health backdrop
State health officials say illicit fentanyl and methamphetamine are now among the leading drivers of overdose deaths in Oklahoma. As part of the response, the Oklahoma State Department of Health shares data dashboards, prevention tools and harm-reduction guidance that state and local leaders reference when shaping enforcement and treatment strategies.
What happens next
The attorney general's office has not yet announced a court date. The case will move through the state court system, and future filings are expected to appear on local dockets. According to reporters and community observers, the announcement also serves as a signal that overdose-related prosecutions will remain a priority for state authorities.
