Ki'Anthony Tyus (2018)
On December 22, 2018, Louisville Kentucky Metro Police Department officers identified a stolen vehicle and began a chase. After the first two officers crashed, Officer Roger Marcum and an officer in another cruiser picked up the pursuit.
Department policy at the time forbade officers from chasing cars unless a violent felony had been committed or a suspect was wanted for a violent crime. 
Marcum used his vehicle to cause the stolen vehicle to crash, killing Tyus and injuring several other occupants.
In January 2019, Tyus' family sued the driver of the vehicle, the department, and Marcum.
The County Attorney's Office, which represented Marcum, argued that Marcum was protected by qualified immunity because his actions were not a substantial factor in causing the crash.
An internal investigation determined that Marcum did not violate the department's policy.
On December 8, 2021, the lawsuit was settled for $600,000.
