State of Indiana, Appellee-Plaintiff

August 7, 2026 Court of Appeals Case No. 25A-CR-3168 Appeal from the DeKalb Superior Court The Honorable Patrick L. Jessup, Judge Trial Court Cause No. 17D02-2405-MR-000002

Opinion by Judge Felix Chief Judge Tavitas and Judge Bradford concur.

Court of Appeals of Indiana | Opinion 25A-CR-3168 | August 7, 2026 Page 1 of 17 Felix, Judge.

Statement of the Case [1] During an arranged drug buy, minors Blake Boese and T.J. stole a bag of drugs

from Coltin Herzog’s minor brother Grayson Aronen, so Herzog chased after

the teens to recover the bag and stabbed Boese, killing him. Herzog was

convicted of voluntary manslaughter and sentenced to 28 years of incarceration.

Herzog now appeals and raises three issues for our review:

1. Whether the State presented sufficient evidence to rebut Herzog’s claim of self-defense; 2. Whether the trial court abused its discretion in identifying mitigating factors; and 3. Whether Herzog’s sentence is inappropriate under Indiana Appellate Rule 7(B).

[2] We affirm.

Facts and Procedural History [3] In May 2024, Herzog was on criminal probation in two separate causes for

burglary as a Level 4 felony and robbery as a Level 5 felony. On May 23, 17-

year-old T.J. messaged 16-year-old Aronen about buying drugs from him.

Herzog agreed to drive Aronen to meet T.J. to sell him the drugs at an address

located in “the trailer court,” 710 Janie Street in Auburn, Indiana. Ex. Vol. I at

103.

[4] At approximately 1:37 p.m., Herzog and Aronen arrived at the arranged

meeting location, and Aronen messaged T.J. that he had arrived. T.J. and

Court of Appeals of Indiana | Opinion 25A-CR-3168 | August 7, 2026 Page 2 of 17 Boese met Herzog and Aronen at Herzog’s vehicle and “hopped in,” Tr. Vol.

III at 196, to discuss the purchase. Boese was carrying an unloaded handgun in

his pocket. During the discussion, Herzog drove to the end of the street and

turned around before parking. After T.J. “noticed [he] didn’t have [his] wallet,”

Tr. Vol. III at 199, he and Boese exited the vehicle and walked “half of a

football field” away, id. at 210, where Boese gave T.J. the handgun.

[5] When Boese and T.J. returned to Aronen’s side of the vehicle, Boese “reached

through the [front passenger-side] window, and he tried to take” Aronen’s blue

bag of drugs, Tr. Vol. III at 200, which he had across his chest and “around his

neck,” id. at 201. After a struggle, the bag ripped, and Boese (who had the blue

bag in his hand) and T.J. “took off running . . . around the car.” Id. at 203.

During the struggle, Herzog, in an attempt to drive away, shifted the vehicle

into neutral, and it began to roll forward. However, Herzog “los[t] interest in

trying to drive away,” removed his knife from the center console, Tr. Vol. IV at

223, and chased Boese and T.J. when they ran away with the bag.

[6] Herzog caught up to Boese and T.J. when they stopped between rows of

trailers, and he swung his knife at T.J. without striking him. Boese started

running again, splitting up with T.J. At approximately 1:51 p.m., T.J. returned

to Boese’s trailer alone.

[7] Meanwhile, Boese ran north between the trailers toward 1108 Irene Street.

When Boese reached 1108 Irene Street, he “pound[ed] on the door” and yelled

for help, saying he had been stabbed. Tr. Vol. II at 213. When resident Alyssa

Court of Appeals of Indiana | Opinion 25A-CR-3168 | August 7, 2026 Page 3 of 17 Bolen opened the door, she “saw two guys standing there. One guy was . . .

pretty much right by the door up on the porch, and then there was another one

at the bottom of the steps,” id., approximately “four, five, six feet from” Boese

and holding a blue bag, id. at 214. Bolen closed the door to ask another resident

for help, and when Kylie Desantie came out from her bedroom, Bolen reopened

the door and saw “the guy that was down on the ground take off running in a

different direction.” Id. at 216. Boese was bleeding heavily, and he told Bolen

he was stabbed by “Preston” and “wanted his mom.” Id. at 217. Bolen called

911 while Desantie began assisting Boese. Desantie “knew [Boese] was going

to die as soon” as she saw him. Id. at 234. “Blood [was] pumping out of”

Boese. Id. “He was panicked[,] scared[,] freaking out[,] super out of breath,”

id., and “[b]egging for his mom,” id. at 238. Boese told Desantie he had been

stabbed and then “just kind of fell in on top of” her. Id. at 234. After they fell,

Desantie looked toward the street and saw someone wearing a camouflage shirt

“messing with” a blue bag and running away. Id. at 235.

[8] Despite first responders’ efforts, Boese died from his injury on the sidewalk in

front of 1108 Irene Street. Boese’s mother walked up shortly thereafter and saw

him “dead, laying on the ground.” Tr. Vol. III at 56.

[9] After Herzog ran away from 1108 Irene Street with the recovered blue bag of

drugs, he returned to his vehicle where Aronen was waiting. Herzog drove

Aronen to Aronen’s friend N.N.’s house; gave Aronen “the bag, the knife,” and

Herzog’s bloody shorts; and “told [Aronen] to get rid of them.” Tr. Vol. IV at

207.

Court of Appeals of Indiana | Opinion 25A-CR-3168 | August 7, 2026 Page 4 of 17 [10] At N.N.’s house, Aronen was carrying a white bag with some drugs and told

N.N. and N.N.’s stepfather that “someone got robbed” in the “trailer park,” Tr.

Vol. III at 40, and that “they stabbed someone in the shoulder,” id. at 41. After

Aronen left, N.N. “checked [his] trash can,” id. at 50, and found “a bloody bag,

a bloody knife . . . THC, that white bag that [Aronen] left with, and bloody

shorts,” id. at 51. N.N. showed the items to his stepfather, who then took them

to “the trailer park” to find a law enforcement officer. Id. at 42.

[11] During the course of their investigation, law enforcement officers learned that

Aronen, Herzog, and Preston were brothers. Officers went to Herzog’s

residence to execute a search warrant. In the washing machine, officers found a

camouflage shirt “consistent with the description [they had] of the suspect[’s]

clothing.” Tr. Vol. III at 17. Both Herzog’s and Boese’s DNA were on the

shirt. The autopsy revealed that Boese sustained a stab wound to his chest that

penetrated his left upper lung, causing his lung to collapse.

[12] The State charged Herzog with murder. 1, 2 At trial, Bolen identified Herzog as

the person she saw at the bottom of the stairs. T.J. testified that he did not

remove the gun from his pocket after Boese gave it to him at any time during

his interactions with Herzog. T.J. also testified to many of the facts as stated

1 Ind. Code § 35-42-1-1(1). 2 In Cause 17D01-2502-MR-000001, the State charged Aronen with murder, assisting a criminal as a Level 5 felony, and obstruction of justice as a Level 6 felony. Aronen pled guilty to assisting a criminal as a Level 5 felony, and the other two charges were dismissed.

Court of Appeals of Indiana | Opinion 25A-CR-3168 | August 7, 2026 Page 5 of 17 above. Herzog argued that he acted in self-defense. In support, Herzog

testified that he stabbed Boese at his vehicle when Boese moved toward him
