Key moments from day 4 of the trial in the death of Patrick Lyoya

On the fourth day of former officer Christopher Schurr's trial for the second-degree murder of Patrick Lyoya, Grand Rapids Police Capt. David Siver faced cross-examination regarding Schurr's use of deadly force, clarifying that while active resistance rarely warrants such force, aggressive acts like grabbing a taser do increase its justification. Defense witness Capt. Chad McKersie described the severe pain of being tased and supported Schurr's fear of incapacitation, though the judge struck his testimony on Schurr's beliefs. Expert Lon Bartel testified on Schurr's exhaustion during the altercation, suggesting it left him with limited options beyond deadly force.
