Mantonia M. Duncan, a 36-year-old man, is facing charges of second-degree murder, armed criminal action, and illegal firearm possession in connection with the death of Jami Duncan, 39, on July 17.
The incident took place late in the evening at a residence on East 54th Street in the North Town Fork Creek neighborhood in Kansas City, Mo. Responding to a 911 call, officers and paramedics discovered the victim in her kitchen, shot multiple times in her head and body.
The accused allegedly entered a residence on July 17 where Jami Duncan and her son were present. Upon discovering them in the kitchen, Mantonia Duncan reportedly commanded Jami Duncan to “lineup” before shooting her three times. The son, who is Mantonia Duncan’s stepson, managed to escape the scene by hiding in his room’s closet.
Court documents reveal that Mantonia Duncan had sent a text message to his brother on the day of the incident, expressing “not feeling right and something being weird.” The brother, in his witness statement, mentioned that he had a phone conversation with Mantonia Duncan, who seemed “very frantic and rambling,” and revealed that he was returning home after a dispute with Jami Duncan.
Following the phone call, Mantonia’s brother had the mother of his 16-year-old daughter locate Mantonia Duncan, who was reportedly intoxicated and on foot. The woman was on a Facetime call with Mantonia’s brother when she discovered Jami Duncan’s body on the kitchen floor, suffering from gunshot wounds. She immediately dialed 911, and Kansas City, Missouri, Police Department officers arrived at the scene around 11 p.m.
Mantonia Duncan is currently being held at the Jackson County Detention Center on a $100,000 cash bail. He is scheduled to appear in court on July 31 for a bond hearing.
