A former Lee's Summit police officer pleaded guilty Tuesday to federal charges for an August 2018 armed bank robbery in southern Lee's Summit that led to a high-speed police chase into Grandview.

Richard Hagerty, 35, of Independence, pleaded guilty in federal court in Kansas City one count each of bank robbery and possessing a firearm during a violent crime. He was a Lee's Summit officer from 2007 to 2016.

According to court documents, on Aug. 28, 2018, Hagerty entered the Central Bank of the Midwest, 1305 N.W. Arborwalk Blvd., just off Missouri 150, wearing a camouflage mask and black gloves. He pointed a Glock .40-caliber at a customer, yelled, “Everybody get down on the floor, this is a robbery” and then pointed the gun at two tellers as he demanded money. Hagerty stole about $7,000 and fled on foot.

A Lee's Summit officer saw Hagerty driving a dark gray Mazda about 2.5 miles away shortly after the robbery, and when Hagerty sped away the officer gave chase, as Hagerty drove erratically in midday traffic, passing through school zones and crossing into oncoming traffic. The chase reached speeds faster than 100 mph.

When the chase ended in Grandview, Hagerty came out with his hands above his head, and the arresting officer immediately recognized him. Inside the Mazda, officers saw a large amount of cash on the driver's seat and front floorboards and recovered the handgun.

Hagerty faces up to 25 years in federal prison for the robbery, plus a consecutive mandatory minimum sentence of seven years for brandishing the gun. He is to be sentenced at a later date.
