In a development that has brought a measure of closure to two grieving families, 31-year-old Thomas Brown of Chandler was arrested and booked into Maricopa County Jail on October 2, 2025, facing two counts of first-degree premeditated murder in the deaths of Arcadia High School students Evan Clark, 17, and Pandora Kjolsrud, 18. The arrests follows a four-month investigation into the Memorial Day weekend shootings that shocked the Phoenix community and highlighted the dangers of remote outdoor recreation.
Thomas Brown, held on a $2 million bond, appeared in court shortly after his booking, where prosecutors outlined preliminary evidence linking him to the crime scene in Tonto National Forest near Mount Ord. Authorities described the killings as a random encounter turned deadly, with no prior connection between the suspect and the victims. The Maricopa County Sheriff’s Office (MCSO) announced the arrest during a press conference on October 3, emphasizing their commitment to thorough forensics that cracked the case.
The victims, both recent juniors at Arcadia High School in Phoenix, had embarked on a short camping trip to celebrate the end of the school year. Clark and Kjolsrud, described by friends and family as inseparable companions with bright futures ahead, left Phoenix on May 25, 2025, in Clark’s SUV, heading to a dispersed campsite off State Route 87. Their bodies were discovered two days later on May 27 by MCSO deputies responding to a welfare check initiated by concerned relatives. The teens had been shot multiple times and dragged from their campsite, indicating a violent altercation.
Initial reports from the scene noted signs of disturbance, including drag marks leading away from the fire pit area, and the victims’ vehicle positioned nearby with its doors ajar. Autopsies confirmed the cause of death as gunshot wounds, ruling out accident or self-inflicted harm. The isolated location, roughly 50 miles northeast of Phoenix in the rugged terrain of Mount Ord, complicated the early stages of the investigation, as the area sees heavy recreational use but limited cell service and foot traffic.
MCSO spokesperson Calbert Gillett stated during the press conference that the agency received over 200 tips from the public in the weeks following the discovery, many of which pointed toward suspicious activity reported over the holiday weekend. “This was a brazen act in broad daylight during a busy camping season,” Gillett said. “The community rallied behind the families, and those leads were instrumental.”

The case drew widespread media attention due to the victims’ youth and the idyllic nature of their outing, prompting vigils at Arcadia High School and online campaigns for justice. Fundraising efforts on platforms like GoFundMe raised tens of thousands for funeral costs and victim support services, reflecting the profound impact on the local area. As of October 6, Thomas Brown’s next court appearance is scheduled for mid-October, where formal charges will be presented to a grand jury. Prosecutors have indicated they will seek the death penalty if convicted, citing the premeditated nature of the crimes.
The Investigation: From Suspicion to DNA Breakthrough
The probe into Clark and Kjolsrud’s deaths began immediately upon the bodies’ discovery, with MCSO deploying a multi-agency task force including forensic specialists from the Arizona Department of Public Safety. Deputies secured the 10-acre crime scene by late afternoon on May 27, collecting over 150 pieces of evidence, including shell casings from a 9mm handgun, bloodied clothing fragments, and discarded latex gloves stained with Kjolsrud’s blood. The gloves, found near the drag path, became a pivotal item; trace DNA inside them matched Thomas Brown’s profile after a routine database search on June 4. Additional DNA from Clark’s SUV interior—specifically on the gear shift and passenger door handle—further corroborated the link, according to a court affidavit unsealed post-arrest.
Thomas Brown emerged as a person of interest within days due to his social media activity. Posts on platforms like Instagram and Facebook, timestamped May 25-26, showed him boasting about a solo camping trip at Mount Ord, complete with geotagged photos of the same trailhead used by the victims. “Roughing it in the pines—best way to unplug,” one post read, accompanied by images of a tent site mere miles from the crime scene.
Detectives interviewed Thomas Brown on June 10 at his Chandler residence, where he claimed to have hiked alone and encountered no one. However, inconsistencies arose: His alibi lacked witnesses, and tire treads from his pickup truck matched impressions near the SUV. MCSO Captain David Lee, who led the interrogation, noted in the press conference that Thomas Brown “provided false and misleading information regarding his involvement,” including a fabricated timeline that placed him elsewhere during the estimated time of death—between 8 p.m. and midnight on May 26.
Forensic ballistics tied shell casings to a weapon later recovered from Brown’s home during a search warrant execution on September 28. The handgun, a Glock 19, bore microscopic scratches matching those on the casings, and gunshot residue tests on Thomas Brown’s clothing from the weekend yielded positive results. Cell phone pings placed his device within a half-mile radius of the site at 9:47 p.m. on May 26, contradicting his statements.
The investigation also involved reconstructing the victims’ last hours via phone records and a half-finished Snapchat story from Kjolsrud showing the pair roasting marshmallows. No motive has been publicly disclosed, but sources close to the case describe it as an opportunistic robbery attempt that escalated when the teens resisted. Over 50 interviews were conducted, including with other campers who reported hearing “popping sounds” around 10 p.m. but dismissed them as fireworks. The DNA match on October 1 prompted Brown’s immediate arrest the following day, ending a manhunt that had quietly intensified in recent weeks.
This breakthrough underscores the role of modern forensics in cold cases, though MCSO officials acknowledged the emotional toll on investigators. “Four months feels like an eternity for families waiting for answers,” Lee said. The affidavit details how Thomas Brown’s military background as a veteran—serving in the U.S. Army until 2018—gave him familiarity with remote terrain, potentially aiding his evasion tactics. No prior criminal record was noted for Brown, a landscaper by trade, but neighbors described him as reclusive. The evidence compilation, spanning digital footprints to biological traces, positions the case for a strong prosecution.
Victims’ Lives Cut Short: Remembering Evan and Pandora
Evan Clark, a 17-year-old from Paradise Valley, was remembered by his mother, Sandra Malibu Sweeney, as “the light of my life, my everything.” In a heartfelt statement released via family channels shortly after the arrest, Sweeney described her only child as far from a “typical teenager.” Evan excelled in Arcadia High’s STEM program, harboring dreams of studying environmental engineering at Arizona State University.
An avid hiker and photographer, he documented Phoenix’s natural wonders on his Instagram, amassing a small following of outdoor enthusiasts. “He wasn’t just book-smart; he had this quiet wisdom, always planning adventures that brought people together,” Sweeney said. Evan’s father, Bill Clark, confirmed the camping trip was a spontaneous post-finals escape, with Evan leaving home around noon on May 25, promising to text upon arrival. The family learned of his death on May 28, shattering what Sweeney called “an insurmountable grief.”
Pandora Kjolsrud, 18, embodied creativity and compassion, according to her mother, Simone Kjolsrud, who tearfully addressed reporters on October 3. “Pandora was a beautiful, brilliant light in this world,” Simone said, her voice breaking. A budding artist and debate team captain at Arcadia, Pandora volunteered at local animal shelters and aspired to pursue graphic design in college. Friends recalled her infectious laugh and talent for sketching fantastical landscapes during lunch breaks.
The two victims had been close since freshman year, bonding over shared classes and mutual love for the outdoors. Their Memorial Day outing was meant to be a simple rite of passage—s’mores, stargazing, and stories about the future. Kjolsrud’s family initiated the missing persons report on May 27 after she missed a planned brunch, leading deputies to the site. Both teens were honor roll students with no history of trouble, their lives intersecting in the tight-knit Arcadia community of about 16,000. Arcadia High Principal Maria Gonzalez issued a statement post-arrest: “Evan and Pandora represented the best of our school—curious, kind, and full of potential. Their loss is a wound we all feel.”
Memorial scholarships in their names have been established at the school, funded by community donations exceeding $50,000. Sweeney’s GoFundMe, titled “Justice for Evan: Honoring My Beloved Son,” details his passions: from backpacking the Superstition Mountains to mentoring younger siblings in photography. Simone Kjolsrud echoed this, noting Pandora’s final text: “Can’t wait to make memories under the stars.” The families, now connected by tragedy, have formed a support network, attending each other’s counseling sessions. “We miss them every day,” Simone said. “But knowing the monster who took them is behind bars allows us to breathe.”
Arrest and Road to Justice: Charges and Community Response
Thomas Brown, a 31-year-old Army veteran residing in a modest Chandler apartment complex, was taken into custody without incident on October 2 at approximately 11 p.m. Bodycam footage released by MCSO shows deputies approaching his door, where he complied peacefully after being read his rights. Booked into the Fourth Avenue Jail, Thomas Brown faces charges carrying a potential life sentence or capital punishment under Arizona law for first-degree murder.
Court records indicate he waived his initial arraignment reading, entering a not guilty plea through counsel. Maricopa County Attorney Rachel Mitchell’s office has assembled a team led by veteran prosecutor Elena Vasquez, who specializes in homicide cases involving forensic evidence. “The state will prove beyond doubt that Thomas Brown’s actions were calculated and cruel,” a spokesperson said.
Public reaction has been one of relief tempered by sorrow. Vigils held outside the jail on October 4 drew over 200 attendees, many holding photos of Clark and Kjolsrud. Arcadia High canceled classes the following day for grief counseling, with attendance voluntary but turnout near 90%. Online, hashtags like #JusticeForEvanAndPandora trended locally, amassing 15,000 posts in 48 hours. Community leaders, including Phoenix Mayor Kate Gallego, commended MCSO’s persistence: “This arrest reaffirms our resolve to protect our youth in Arizona’s wild spaces.” Experts note the case’s implications for camping safety, with the U.S. Forest Service planning enhanced patrols in Tonto National Forest for the upcoming season.
As pretrial motions unfold, the focus shifts to healing. Both families expressed gratitude to Detective Fernando De La Torre, credited with the DNA pivot. Sweeney added, “This closure means no one else has to worry—he can’t harm anyone now.” The road ahead includes depositions and expert testimonies, but with ironclad evidence, conviction seems likely. This tragedy serves as a stark reminder of vulnerability in nature’s embrace, urging vigilance even in familiar trails. For now, Phoenix mourns two bright stars extinguished too soon, while justice begins its deliberate march.
