Background
Desman LaDuke told his girlfriend he intended to kill himself and had a gun. Police responded to a suicide threat and found LaDuke inside his home refusing to exit or identify himself. After a Special Response Team surrounded the house, LaDuke appeared at a window holding firearms, waving them, and yelling profanities. Officer Joseph Horton shot and killed LaDuke. John Norman, administrator of LaDuke’s estate, sued the officers under Section nineteen eighty-three and state law, alleging excessive force and policy violations. The district court granted summary judgment to the defendants.
The court’s reasoning
The court reviewed the excessive force claims de novo. For the use of force theory, the court found that while there is a clearly established right not to be shot absent probable cause of a threat, the specific rule required to defeat qualified immunity must be more particularized. The court distinguished this case from Heeter versus Bowers, noting that LaDuke was brandishing a gun rather than standing with hands raised. For the show of force theory, the court found no clearly established rule prohibiting officers from pointing guns at an armed, non-compliant subject. Regarding the official capacity claim, the court held the plaintiff waived the argument by failing to address the municipal liability prong in his opening brief. Finally, the court affirmed the denial of a motion to amend the complaint to add a failure-to-follow-policy theory, citing undue delay and prejudice to the defendants.
What it means going forward
The ruling reinforces that qualified immunity protects officers in high-stakes mental health crises where the suspect is armed and non-compliant, even if the suspect is mentally ill. It also clarifies that appellate litigants must explicitly argue all prongs of a Monell claim in their opening brief to avoid waiver.
