Case Summary [1] While investigating a suspected shoplifting, Highland Police Officer Michael

Yonkman was injured when the suspect reversed his vehicle into Yonkman, pinning him against a parked car. Yonkman filed a complaint against the suspect and the police department’s uninsured/underinsured motorist (UIM) provider, Argonaut Insurance Company (Argonaut), seeking damages for his injuries. Argonaut moved to dismiss the complaint, asserting it was filed outside the statutory limitations period, and, in any event, Yonkman was not entitled to UIM coverage because he was not occupying his police cruiser when he was injured. After the trial court converted Argonaut’s motion to one for summary judgment, Yonkman filed a cross-motion for partial summary judgment on the timeliness of his complaint and his occupancy of a covered vehicle. The trial court ruled in Argonaut’s favor, and Yonkman appeals.

[2] We hold that Yonkman filed his complaint within the two-year limitations period and that he maintained a sufficient relationship with his police cruiser during the investigation to be “occupying” it for purposes of UIM coverage. We thus reverse the trial court’s judgment and remand with instructions for the court to deny Argonaut’s motion and grant Yonkman’s cross-motion.

Facts and Procedural History [3] On February 17, 2023, a loss prevention officer suspected Jomo Wilson of

shoplifting from a Kohl’s department store in Highland. Yonkman was dispatched to the store to investigate, and he drove his department-issued police cruiser to the store’s parking lot. When Yonkman arrived, Wilson had left the store and was pushing a shopping cart through the lot toward his Ford Escape.

[4] Yonkman parked his cruiser near the Escape. Then he exited the cruiser, left the engine running, and started walking toward Wilson. Though Yonkman instructed Wilson to stop, Wilson started running and managed to climb into the driver’s seat of the Escape before Yonkman caught up to him. Yonkman opened the driver’s door to arrest Wilson, but Wilson accelerated the vehicle in reverse. The open driver’s door dragged Yonkman backwards and crushed him between it and another parked car, injuring him. 1 Only sixty seconds passed between Yonkman exiting his cruiser and Wilson reversing into him.

[5] On February 18, 2025—two years and one day after the incident—Yonkman filed his complaint against Wilson and Argonaut, seeking in part to recover damages for his injuries under the police department’s UIM policy. Argonaut responded to the complaint by filing a motion to dismiss under Indiana Trial Rule 12(B)(6), asserting two arguments. First, it contended that Yonkman filed the complaint outside the two-year limitations period provided by Indiana law and the terms of the policy. Second, Argonaut asserted Yonkman was not an “insured” as defined by the policy because he was not “occupying” his cruiser at the time of the incident. Appellant’s Appendix Vol. 2 at 29.

1 The nature and extent of Yonkman’s injuries are not clear from the record before us.

[6] Argonaut attached several exhibits to its motion, including a copy of the policy, the charging information filed against Wilson for numerous offenses stemming from his encounter with Yonkman, the probable cause affidavit filed in Wilson’s criminal case, and Wilson’s May 16, 2025 plea agreement, in which he pled guilty to Level 3 felony aggravated battery against Yonkman. Before Yonkman responded to the motion to dismiss, the trial court converted it to a motion for summary judgment and enlarged Yonkman’s deadline to respond.2

[7] Yonkman’s response in opposition to Argonaut’s motion was timely, and he made a cross-motion for partial summary judgment on the timeliness of his complaint and the applicability of UIM coverage. First, he argued his filing of the complaint was timely because Indiana Code section 1-1-9-1 defined the two- year anniversary of the incident, February 17, 2025, as a legal holiday commemorating George Washington’s Birthday. Thus, Trial Rule 6(A)(3) extended the limitations period through February 18, 2025. Second, Yonkman claimed that though he was outside his cruiser when Wilson injured him, he nonetheless occupied it under the four-factor test developed by this Court in Miller v. Loman, 518 N.E.2d 486 (Ind. Ct. App. 1987), reh’g denied.

2 This was necessary because Argonaut referenced matters outside the pleadings in its motion to dismiss. See Ind. Trial Rule 12(B) (“If, on a motion [under Rule 12(B)(6)], matters outside the pleading are presented to and not excluded by the court, the motion must be treated as one for summary judgment and disposed of as provided in Rule 56.”).

[8] Among other exhibits, Yonkman designated his own affidavit, in which he recounted the February 17, 2023 incident. He also explained what he intended to do had Wilson not fled:

If Wilson had complied with my verbal response to stop, I would have conducted a theft investigation, which would have required me to return to my police [cruiser] to run Wilson’s name/identity through [the] . . . software system located within my police issued laptop computer inside the police vehicle. Subsequent to the incident, I became aware that Wilson had an active warrant for impersonating a federal police officer. Accordingly, [the software] would have alerted me to the active warrant, and I would have arrested Wilson for the outstanding warrant.

Further, I would have used the police vehicle to transport Wilson following the arrest.

Appellant’s App. Vol. 4 at 93. Yonkman further alleged that “[h]ad Wilson not pinned [him] between his Ford Escape and another parked car, [he] would have returned to [his] police vehicle to initiate a pursuit on Wilson . . . .” Id.

[9] In a combined reply and response to Yonkman’s arguments, Argonaut designated a memorandum issued by then-Governor Eric Holcomb informing Indiana state employees “of the 2025 state holidays and the dates on which they [would be] observed.” Appellant’s App. Vol. 7 at 11. As shown by that memorandum, Governor Holcomb had exercised his authority under Indiana Code section 1-1-9-2 to shift the observance of Washington’s Birthday to December 26, 2025. Thus, according to Argonaut, February 17, 2025, was not a legal holiday and Trial Rule 6(A)(3) did not apply.

[10] On December 1, 2025, the trial court held a hearing on the motions for summary judgment. There, the parties’ arguments largely tracked the contentions made in their written submissions. However, at the conclusion of the hearing, Yonkman’s attorney asked the court to take judicial notice of Lake County Ordinance 1502D (the Ordinance), which declared all county offices closed on February 17, 2025, in observance of Presidents Day. Because Lake County offices were closed on the two-year anniversary of the incident, Yonkman argued Trial Rule 6(A)(4) extended the limitations period by one day. The court took the motions under advisement, including Yonkman’s request for judicial notice of the Ordinance.
