Background
Thomas Charles Olson was convicted by a jury of second-degree murder and felony-firearm after a hunter was shot in the back of the head at Michigan’s Rose Lake Game Area in November 2018. Investigators found boot prints and a nearby plastic bag containing deer spray and Olson’s DNA. Cell-phone evidence placed Olson near the scene, while text messages showed him joking about the killing and using racial slurs concerning the victim’s ethnicity.
Prosecutors also introduced Olson’s Internet searches for a “missing hunter” and local law-enforcement agencies before the victim’s death became public, as well as later searches concerning Costa Rica, extradition, and the homicide investigation. After trial, Olson sought a new trial, alleging that counsel should have consulted a firearms expert, challenged the prosecutor’s characterization of the footprint evidence, and offered evidence explaining his early knowledge of the killing. Following an evidentiary hearing, the trial court denied the motion.
The Court’s Holding
The Michigan Court of Appeals affirmed. Without deciding whether counsel’s performance was deficient, the court held that Olson failed to establish prejudice—meaning a reasonable probability that the verdict would have been different absent counsel’s alleged errors.
A defense firearms expert would, at most, have reinforced trial testimony that no firearms evidence connected Olson’s gun to the recovered bullet fragments. An objection to the prosecutor’s unsupported assertion that a “tread path” linked the victim’s body to the bag bearing Olson’s DNA would not have materially altered the case because that argument was only one component of the prosecution’s proof. And evidence offered to explain Olson’s advance knowledge of the killing could have opened the door to GPS evidence placing him near the victim’s body and damaging rebuttal testimony.
Considering the totality of the evidence—including Olson’s presence near the scene, his DNA, his text messages, and his Internet searches—the court concluded that none of the asserted errors undermined confidence in the verdict. The trial court therefore did not abuse its discretion by denying a new trial.
Key Takeaways
- An ineffective-assistance claim fails without proof of prejudice, even if counsel’s performance is assumed to have been deficient.
- Counsel’s failure to obtain cumulative expert testimony did not create a reasonable probability of a different verdict.
- The prosecutor overstated the footprint evidence, but the unchallenged argument was not prejudicial given the substantial independent circumstantial evidence of guilt.
Why It Matters
The decision illustrates how appellate courts assess ineffective-assistance claims against the prosecution’s entire evidentiary case rather than evaluating each alleged attorney error in isolation. It also shows that a questionable strategic choice or unmade objection will not justify a new trial unless the defendant demonstrates a meaningful likelihood that it affected the verdict.
