COURT OF APPEALS

PEOPLE OF THE STATE OF MICHIGAN, UNPUBLISHED May 19, 2026 Plaintiff-Appellee, 11:28 AM

v No. 372765 Kent Circuit Court DIMARIO MARQUIS PARKER, LC No. 23-005677-FC

Defendant-Appellant.

Before: WALLACE, P.J., and LETICA and FEENEY, JJ.

PER CURIAM.

Defendant appeals as of right his jury trial convictions for: (1) assault with intent to murder, MCL 750.83; (2) carrying a concealed weapon (CCW), MCL 750.227; and (3) carrying a firearm during the commission of a felony (felony-firearm), MCL 750.227b. The trial court sentenced defendant to serve: (1) 15 to 25 years, (2) 1 ½ to 5 years, and (3) 2 years in prison, respectively. 1 We affirm.

I. FACTS

This case arises out of a driving altercation involving coworkers, which escalated when defendant shot Desmond Self five times.

Defendant and Self worked together and previously lived in the same apartment complex. In February 2023, Self filed a workplace-complaint about another coworker—defendant’s friend— bringing a gun into the workplace. The workplace established a no weapons policy. Thereafter, defendant and two others filed complaints against Self for his “work etiquettes.” The complaints against Self were found to be “unsubstantiated,” and a meeting occurred between Self and the other complainants. Self and the other complainants resolved their differences, but defendant did

-1- not participate. Self formally asked management to be moved to a different department so that he would be separated from defendant.

On April 28, 2023, defendant and Self left work at the same time, with defendant’s vehicle directly ahead of Self’s vehicle. Defendant and Self both drove to the apartment complex where Self lived.2 Defendant claimed that Self was chasing him on their way to the apartment complex, which Self denied.3 When defendant turned into the entrance of the apartment complex, he slammed on his brakes. Defendant claimed that Self’s vehicle “tapped” his bumper; Self testified that he did not hit defendant’s vehicle, but it was very close. Once defendant moved his vehicle forward, Self drove up next to defendant and rolled his window down. A verbal argument ensued, during which defendant asked why Self was following him, and Self responded that he was simply going home.

Self began to drive away, but because he saw defendant get out of his vehicle and begin “ranting,” with his hands raised and waving, Self decided to reverse his vehicle back toward the incident so that he could hear what defendant was saying. Defendant starting shooting Self as Self was reversing and again when he was stationary. Self reacted and said: “[Y]ou just shot me . . . . [D]ude, I’m dying here, bro, can you at least call and get me some help?” Defendant responded by shooting Self and stating: “I am not to be f***ed with out here and quit f***ing playing with me.”

At trial, defendant asserted that he shot Self in self-defense because he honestly believed that Self was attempting to reverse into him, and he feared for his life. Multiple eyewitnesses testified that they did not see Self attempt to strike defendant with his vehicle, but they did see defendant shoot Self. The jury found defendant guilty, and the trial court sentenced defendant, as stated earlier. Defendant now appeals.

II. INEFFECTIVE ASSISTANCE OF COUNSEL

On appeal, defendant argues that defense counsel was ineffective for failing to investigate and provide evidence of Self’s prior assaultive criminal history at trial. We disagree.

A. PRESERVATION AND STANDARD OF REVIEW

Because defendant did not raise this issue in a motion for a new trial or evidentiary hearing filed in the trial court, or in a motion to remand for an evidentiary hearing filed in this Court, it is not preserved for appellate review. See People v Abcumby-Blair, 335 Mich App 210, 227; 966 NW2d 437 (2020); People v Sabin (On Second Remand), 242 Mich App 656, 658; 620 NW2d 19 (2000). When a claim of ineffective assistance of counsel is not preserved, “our review is limited to errors apparent on the record.” People v Unger, 278 Mich App 210, 253; 749 NW2d 272 (2008).

2 Defendant claimed that he was heading to pick up his daughter from the bus stop that was located within the apartment complex. 3 A detective testified that there were no reports of a vehicle chase or reckless driving on the day of the incident.

-2- B. ANALYSIS

In Strickland v Washington, 466 US 668, 687; 104 S Ct 2052; 80 L Ed 2d 674 (1984), the United States Supreme Court established a two-prong test that a defendant must meet to prove that his or her counsel’s assistance was so defective as to require a new trial. The test is as follows:

First, the defendant must show that counsel’s performance was deficient. This requires showing that counsel made errors so serious that counsel was not functioning as the “counsel” guaranteed the defendant by the Sixth Amendment. Second, the defendant must show that the deficient performance prejudiced the defense. This requires showing that counsel’s errors were so serious as to deprive the defendant of a fair trial, a trial whose result is reliable. [Id.]

Stated more simply, “[t]he defendant must show that there is a reasonable probability that, but for counsel’s unprofessional errors, the result of the proceeding would have been different.” Id. at 694. To show that a counsel’s performance was deficient, a defendant “must identify the acts or omissions of counsel that are alleged not to have been the result of reasonable professional judgment.” Id. at 690. “The court must then determine whether, in light of all the circumstances, the identified acts or omissions were outside the wide range of professionally competent assistance.” Id

Because there are countless ways to provide effective assistance in each case, courts “must indulge a strong presumption that counsel’s conduct falls within the wide range of reasonable professional assistance; that is, the defendant must overcome the presumption that, under the circumstances, the challenged action might be considered sound trial strategy.” Id. at 689 (quotation marks and citation omitted). “Reviewing courts are not only required to give counsel the benefit of the doubt with this presumption, they are required to affirmatively entertain the range of possible reasons that counsel may have had for proceeding as he or she did.” People v Gioglio (On Remand), 296 Mich App 12, 22; 815 NW2d 589 (2012) (quotation marks and citation omitted), vacated in part on other grounds 493 Mich 864 (2012).

In this case, defendant argues that defense counsel failed to investigate and introduce evidence of Self’s assaultive criminal history, which would have supported defendant’s claim of self-defense. “The failure to reasonably investigate a case can constitute ineffective assistance of counsel.” People v Anderson, 322 Mich App 622, 630; 912 NW2d 607 (2018). But because defendant offers no evidence in support of his assertion that defense counsel failed to investigate, “he has not established the factual predicate for his claim.” Id.
