A Grandview man pleaded guilty in federal court Thursday to his role in a conspiracy that included at least 27 armed robberies over three months in 2016 – the last robbery ending with officers fatally shooting one suspect outside a store in Blue Springs.

With his guilty plea, Deonte Collins-Abbott, 23, admitted that he committed eight of those armed robberies, between Feb. 3 and March 24, 2016. He and co-defendants robbed businesses in Blue Springs, Independence, Raytown, North Kansas City, Kansas City, Missouri, and Kansas City, Kansas. Though a sentencing hearing will be scheduled for a later date, Collins-Abbott will be sentenced to 25 years in federal prison without parole, under terms of the plea agreement.

Collins and co-defendant Shannon Thomas of Shawnee, Kansas, were arrested the morning after a robbery at Walgreens on Missouri 7 in south Blue Springs. The two men and Jermon Seals of Shawnee had been followed by agents of the FBI and U.S. Marshals Service and by Kansas City Police.

The men took money and cough syrup at gunpoint at the Walgreens, and when they left after 3 a.m., the officers confronted the suspects outside the drugstore. The defendants failed to obey repeated commands, and Seals turned and pointed a gun toward the officers, who then fired at him. Seals, 22, was killed, and the other two were arrested after a short foot chase.

Two other co-defendants in the case, 25-year-old Demetrius Nelson of Kansas City and 26-year-old Parrise “Kilo” Black of Grandview, have already pleaded guilty. Thomas, Kevin “Kilo Ali” Thompson-Randell of Kansas City and Frank “Fonzi” Garner of Grandview also were charged in the 36-count second superseding indictment returned by a federal grand jury August 2017.

In all of their robberies, the defendants consistently displayed handguns in a threatening manner and were violent and aggressive toward victims, and a victim was shot in one of the robberies.
