On November 10, 2017, 30-year-old Jennifer L. Zimmerman Portillo was shot and killed inside a residence in the 4900 block of East 17th Street in Kansas City, Missouri. The same incident also left her husband, Victor Portillo, and 25-year-old Yessenia Ahumada dead. Officers arrived after a report of a shooting around 10:00 a.m.; two victims were found deceased at the scene and a third, initially alive, later died at a hospital.

Investigators linked the killings to a drug transaction that had been arranged the night before. Court documents say Ahumada, identified as the ex-girlfriend of 27-year-old Deaundre J. Brown, set up a marijuana purchase; Brown allegedly intended to buy 20 pounds for $34,000 and returned the next morning when the deal was not completed. Surveillance video, cellphone records and witness statements place Brown and his vehicle near the house before and after the shootings; a witness reported hearing gunfire and seeing a white sedan speed away. Charging papers accuse Brown of knowingly shooting Jennifer Zimmerman Portillo.

Did anyone in the area see the white sedan or have information about the meeting that morning?
