State of Indiana, Appellee-Respondent

June 23, 2026 Court of Appeals Case No. 25A-PC-2706 Appeal from the Lake Superior Court The Honorable Kathleen A. Sullivan, Magistrate Trial Court Cause No. 45G03-2406-PC-11

Opinion by Judge Mathias Judges Kenworthy and DeBoer concur.

Court of Appeals of Indiana | Opinion 25A-PC-2706 | June 23, 2026 Page 1 of 31 Mathias, Judge.

[1] Lydia Conley appeals the post-conviction court’s denial of her petition for post-

conviction relief. Conley raises three issues for our review, which we restate as

follows:

1. Whether her trial counsel performed reasonably when he failed to object to a witness’s testimony that Conley had told the victim that Conley was going to shoot the victim sometime before the victim was found shot to death.

2. Whether her trial counsel performed reasonably when he did not object to certain surveillance videos and did not proffer a supplemental reasonable-theory-of-innocence jury instruction.

3. Whether the post-conviction court erred when it denied Conley’s petition.

[2] We agree with Conley that her trial counsel’s failure to object to the witness’s

testimony was unreasonable, and, had he lodged a hearsay objection to that

testimony, the trial court would have been required to sustain the objection.

However, we conclude that Conley has not met her burden to show that her

trial counsel acted unreasonably with respect to the surveillance videos and the

supplemental jury instruction, and we conclude that her counsel’s failure to

object to the witness’s testimony is, on this record, insufficient to show that the

post-conviction court erred when it denied her petition.

Court of Appeals of Indiana | Opinion 25A-PC-2706 | June 23, 2026 Page 2 of 31 Facts and Procedural History [3] In 2018, Conley began dating Delilah Martinez, and, in the summer of 2019,

Conley and her daughter (Felicia) moved into Martinez’s Hammond 1 residence

with Martinez’s children (including her daughter, Desha, who was around

eighteen years old). Conley and Martinez’s relationship was described as

“toxic” early on, and it only “got worse” over time. Trial Tr. Vol. 3, p. 174.

Among other problems, Conley was also in a romantic relationship with

Madeline Mendoza, a relationship that Conley had been in since 2005.

[4] In October 2019, Martinez learned of Conley’s relationship with Mendoza, and

Martinez ended her relationship with Conley. Around the same time, Mendoza

learned about Martinez, and Mendoza also ended her relationship with Conley.

Conley “moved out” of Martinez’s home (although Felicia did not), and

Martinez quickly “move[d] on.” Id. at 178. In particular, around the time of her

breakup with Conley, Martinez began dating Lucas Xavier Mercado. Mercado

was married at the time, and, when his wife learned of the affair sometime later,

she was “not happy.” Trial Tr. Vol. 4, p. 41.

[5] Between October 24 and October 26, 2019, Conley sent Martinez a slew of text

messages that, when read aloud, cover thirteen pages of the trial transcript. 2 See

Trial Tr. Vol. 5, pp. 195-208. Among other things, Conley repeatedly asked if

1 Although legally in Hammond, Martinez’s residence had a Whiting address. 2 This does not include messages Conley sent to Martinez through apps.

Court of Appeals of Indiana | Opinion 25A-PC-2706 | June 23, 2026 Page 3 of 31 Martinez was “with someone,” and, if so, whether that person was “a girl.” Id.

at 196. Conley also repeatedly lamented the loss of the relationship and a desire

to reconcile. At one point, Martinez responded and told Conley, “[i]f you don’t

stop [I’m going to] block you.” Id. at 201. Conley replied, “[b]lock me because

I’m broken[?]” Id. at 202.

[6] By the early evening hours of October 26, Martinez had had her fill of the text

messages and told Conley, “I’m on my way to make a police report . . . .” Id. at

205. Conley’s text messages turned more aggressive after that, with Conley

saying, among other things: “F*ck you, . . . I don’t care what you do”; “I don’t

want no men around my daughter”; and, at 10:07 p.m. on October 26, “I’m

sleeping. I have to work. Attend to your little boy.” Id. at 205-07.

[7] But Conley did not go to sleep and, instead, texted Martinez again shortly

before midnight, asking Martinez to “call” and then accusing Martinez of being

“with him,” an apparent reference to Mercado. Id. at 208. And, at 2:26 a.m. on

October 27, Conley texted Martinez: “Check your message on Facebook,

clown.” Id. Just a few minutes before that text, Conley had said to Martinez on

Facebook: “Damn . . . you move so fast with a kid who could date your

daughter, but it’s cool. Enjoy yourself in life. I’m out. . . . Don’t call me when

that [racial slur] cheating on you.” Trial Tr. Vol. 6, p. 10.

Court of Appeals of Indiana | Opinion 25A-PC-2706 | June 23, 2026 Page 4 of 31 [8] Meanwhile, Desha was dating Jose Echabarria. 3 Unfortunately, Desha

suspected Jose of “cheating,” and Desha told Martinez of her suspicion. Trial

Tr. Vol. 3, p. 181. In the evening hours of October 25, Martinez and Mercado

accompanied Desha to a party where they expected to find Jose, but Jose was

not there. Upon arriving at the party, Mercado “grabbed a brick and threw it

through the window.” Id. at 182. They then left and went to Jose’s house; Jose

was there with several family members and other acquaintances. Mercado “got

out [of] the car” and “punched [Jose] in the face.” Id. at 183. When an older

family member stepped in, Mercado punched him too. They then left Jose’s

house and went back to Martinez’s house.

[9] Not long after, Jose messaged Desha about Mercado. Jose was “upset” and

“wanted to confront” Mercado. Id. at 184-85. Desha said she “did not” know

who Mercado was and had only just met him through her mother. Id. at 184.

Sometime on October 26, Jose told Desha that he gave Desha’s address

(Martinez’s residence) to one of his brothers. Id. at 246. But Jose considered

Martinez like “a mother” to him, and he was clear that he was not “upset” with

Martinez and did not “blame[ her] at all” for Mercado’s behavior. Id. at 185-86.

[10] October 26 was also the day that Conley’s text messages with Martinez turned

more aggressive. That day, Conley moved Felicia out of Martinez’s residence

using Conley’s 2011 brown Buick sedan. Around 7:38 that evening, Conley

3 When he spelled his own name at trial, Jose did not specify the use of any accent marks. See Trial Tr. Vol. 5, pp. 78-79.

Court of Appeals of Indiana | Opinion 25A-PC-2706 | June 23, 2026 Page 5 of 31 asked Monica Graham,4 Conley’s now-sister-in-law who lives in Chicago, if

Conley could borrow Graham’s 2013 gray Chevy Malibu for a few hours.

Graham had never previously lent her car to Conley, and Graham informed

Conley that the Malibu had tire-pressure issues and might be out of oil. But

Conley insisted on needing to use the Malibu despite the issues, and so Graham

relented.

[11] The evening of October 26, Martinez was supposed to go to a Halloween party

with Vanessa Vera, a friend from work. Vera took her children to Martinez’s

residence for Desha to babysit them, but Martinez was not there. Vera spoke
