v.

LOLA FELIPA LUNA,

Filed: October 30, 2025

Petitioner.

STEPHENS, C.J.—Lola Felipa Luna got in a fight with S.P.T., another teenage girl she knew only through social media. S.P.T. arrived outside Luna’s home and started the fight by punching Luna, who responded using her pocketknife.

S.P.T. died of her injuries, and the State charged Luna with murder, causing her to be tried as an adult.

At trial, the State was allowed to show social media posts by Luna and video of her police interrogation to argue that she had a preexisting fixation on stabbing someone and showed no remorse after the fight. Luna argued self-defense and offered additional social media evidence, including an image she was sent before the

State v. Luna, No. 103251-0

fight, which she believed showed S.P.T. threatening her with gang violence. Following 13 days of trial, a jury found Luna guilty of intentional but not premeditated murder.

Luna challenges several evidentiary rulings and argues that the court should have applied newly enacted RCW 13.40.740 to exclude evidence from the interrogation. These rulings required the trial court to apply centuries-old legal doctrines—waiver of constitutional rights, res gestae, and the foundation requirement for evidence—in a modern context, involving two things the law has not always adequately understood: young people and social media. Courts must meaningfully consider a defendant’s youth when assessing whether they understood their constitutional rights well enough to waive those rights and proceed with an interrogation. Courts must also examine social media evidence in the context in which it arises and in light of the purpose for which it is proffered.

We hold that the court here erred in applying these principles. While RCW 13.40.740 does not apply, Luna did not validly waive her right to silence, and evidence from her interrogation should not have been admitted. Further, several evidentiary rulings concerning social media evidence undermined the fairness of the trial and the soundness of the verdict. We therefore vacate the jury verdict and remand for further proceedings consistent with this opinion.

FACTS

Luna and S.P.T. had never met in person before the day of their fight, but they knew of each other through social media. Luna was also connected on social media with H.D., a younger teenage girl who was close friends with S.P.T. and who thought of S.P.T. as a big sister. Luna had just turned 16 around a month before the fight with S.P.T. S.P.T. was also 16 at that time, and H.D. was about two years younger than both Luna and S.P.T.

In August 2020, five months before the fight with S.P.T., Luna started a fight with H.D. at the mall because H.D. had been talking to Luna’s ex-boyfriend. The fight lasted less than a minute, and neither Luna nor H.D. was seriously injured. This was the only time Luna and H.D. met in person. Luna said she believed that after this fight, she had made up with H.D., and they became cordial and friendly with each other again on social media. 4 Verbatim Rep. of Proc. (VRP) at 1224-25.

On January 29, 2021, Luna received messages and videos from H.D. and other people, seeking a fight with Luna. They sent her addresses of houses for her to go to that night so they could fight. Luna declined the invitation to fight and went to sleep.

The next day, S.P.T. contacted H.D. saying she wanted to fight Luna because they “had drama,” part of which related to the earlier fight at the mall between Luna and H.D. 2 VRP at 456-57. S.P.T. asked H.D. to text Luna and say that H.D. wanted

State v. Luna, No. 103251-0

to fight Luna. H.D. did so. This surprised Luna because she thought that any prior issues with H.D. had been dealt with, including those from the night before. 2 VRP at 457; 4 VRP at 1318. Luna replied by sending H.D. her address and telling H.D. to come to her house. Luna testified she did not actually believe that H.D. wanted to fight her and expected that even if she did, they could talk through their issues and avoid fighting. 4 VRP at 1318-19. Unbeknown to Luna, H.D. had sent the address to S.P.T. One of S.P.T.’s friends drove her to Luna’s house, and another of S.P.T.’s friends and S.P.T.’s infant daughter came along in the car. H.D. did not go with them.

After responding to H.D.’s message, Luna communicated with two of her friends about H.D. They shared a video of the earlier mall fight between Luna and H.D., which Luna had posted on TikTok shortly after that fight with music added to it.

At some point before S.P.T. arrived at her house, Luna received a text saying that H.D. was six minutes away, so she prepared to step outside her front door. Before stepping outside, she looked through a drawer in her dining room for her pocketknife and put it in her pocket. Luna testified that she put her pocketknife in her pocket or purse every time she stepped out of her house, and that she carried it for multiple reasons, including opening packages and self-protection. 4 VRP at 1320.

Luna opened her front door and stood in the doorway, looking outside. As she started to turn back inside, she heard yelling coming from the street, which is several steps down a slope from her front yard. She stepped outside onto the porch and then further down onto a paved walkway leading to the gate in the chain link fence that surrounds her house. She then saw someone she did not immediately recognize walk up the steps to her house, come through the gate, and continue into the yard to stand in front of her. After a second, Luna recognized this person as S.P.T.

Luna and S.P.T. began talking, and their exchange turned into a verbal altercation. Luna testified that she became fearful that the verbal altercation would turn physical, so she pulled the pocketknife out of her left pocket, slipped it behind her back, opened it up, and held it concealed behind her back in her right hand. 4 VRP at 1324-25.

The altercation turned physical when S.P.T. came at Luna and punched her in the head with her right fist. Luna unsuccessfully attempted to block the first punch with her left hand, and when the punch hit her head, she reacted by starting to stab at S.P.T. with the pocketknife in her right hand. S.P.T. continued to punch Luna, mostly in the head, and Luna continued to slash or stab S.P.T. with her pocketknife. S.P.T. had a hold on Luna and pulled her head down so that Luna could only see their feet. At some point, S.P.T. pushed Luna up against the chain link fence.

State v. Luna, No. 103251-0

Eventually, Luna stopped slashing with her pocketknife, and S.P.T. continued punching her around five more times before stopping. In total, S.P.T. punched Luna around 38 times and Luna slashed or stabbed S.P.T. around 27 times. 4 VRP at 1395-96.

The fight lasted less than 1 minute. One of S.P.T.’s friends and Luna’s boyfriend each captured the fight on a cell phone video. 1 After the fight, S.P.T. walked back down the steps and across the street to the car she had arrived in, and Luna went inside her house. Around 5 or 10 minutes later, four police officers arrived at Luna’s front door. Luna’s stepdad answered the door, and the police asked to speak with Luna, who came to the door. The police asked to come inside to talk, and Luna’s stepdad allowed them to do so. They did not give Luna a Miranda2 warning at this time. Police summoned medical aid from the fire department to assess Luna’s injuries. The aid personnel bandaged Luna’s hands and advised her that she may need stitches in the future but that it was not urgent and she did not need to go to the hospital immediately.
