Legal Team for Family of Amir Locke Provides Update on Investigation Into Police Killing of Amir Locke

February 16, 2022

Nationally renowned civil rights attorneys Ben Crump, Jeff Storms, and Antonio Romanucci have released the following statement to update the public on important information learned about Minneapolis Police Officer Mark Hanneman, who shot and killed Amir Locke on February 2, 2022:. 

“We’ve learned that at least until last year, Officer Hanneman was a Minneapolis Field Training Officer (FTO), like both former officers Derek Chauvin and Kim Potter. This finding is also consistent with media reports that, under the current MPD administration, the MPD continues to demonstrate a pattern of promoting officers with serious disciplinary histories. The information about Officer Hanneman serving as an FTO appears to be the latest example of how bad practices continue to be passed down to new officers in departments like Minneapolis, resulting in constitutional violations throughout the community and, at times, resulting in unnecessary and needless death.

“We have also discovered that in July 2021, criminal charges were dismissed against an individual because Officer Hanneman violated that individual’s constitutional rights to be free from search and seizure. That illegal search and seizure also occurred during an MPD SWAT team warrant execution and was executed by Hanneman on someone who, like Amir Locke, was NOT the subject of the search warrant.  The opinion dismissing the case reflects that Hanneman did not understand written MPD policy.  The opinion also reflects that MPD SWAT had a custom and practice of engaging in unconstitutionally excessive searches and seizures of non-subjects of warrants when conducting SWAT team raids. 

“Finally, our investigation also revealed that a judgment was entered against Officer Hanneman in a federal civil rights action in 2015 for engaging in an illegal search and seizure. 

“While our investigation is in the very early stages, we believe these facts are important for the public to be aware of as we continue to analyze the many long-standing systemic failures of the MPD and the actions of the responsible parties who caused Amir Locke’s death.
