A suspect has been busted more than four months after two teens were found gunned down in a remote section of an Arizona national forest.

Thomas Brown, aged 31, was taken into custody by police on Thursday following an extensive investigation into the murders of Pandora Kjolsrud, 18, and Evan Clark, 17, in Tonto National Forest.

A video provided by the Maricopa County Sheriff’s Office showed Brown being led from a deputy’s vehicle into the sheriff’s headquarters, where he was booked and detained in a holding cell.

The circumstances connecting Brown to the crime remain unclear, and details about his arrest and the charges against him are expected to be released later on Friday, according to the sheriff’s office.

The teens were friends who both attended Arcadia High School in Phoenix, approximately 64 miles southwest of the national forest.

They were found with fatal gunshot wounds to the head near Mount Ordo on the morning of May 27.

Officials at the time described their deaths as suspicious as they opened up the homicide investigation.

“At this time, the circumstances surrounding their deaths are being treated as suspicious,” Maricopa County Sheriff’s Office Sgt. Joaquin Enriquez said, according to Fox 10 Phoenix.

Fundraisers were set up to help both teens’ families fund celebrations of life after they held private funerals.

Kjolsrud was remembered for her “vivacious personality” and smile.

“She was a beautiful human being and a bright light in this world who loved every single person she met and had a unique ability to make every person feel special,” Kathryn Leonard said on GoFundMe. “The outdoors is where she truly felt at home. She loved camping, horseback riding, kayaking and hiking with friends and family.”

Kjolsrud’s mother, Simone Kjolsrud, said her heart was shattered into a million pieces after learning of her daughter’s death.

“Rest in peace my beautiful girl,” the grieving mother wrote on Facebook.

Clark’s mother, Sandra Malibu Sweeney, penned a touching tribute to her son on a separate GoFundMe.

“Evan Clark was my only child and my beloved son. This last week Evan was taken from me, and my level of grief feels insurmountable. I find myself at a complete loss to imagine a life without him. It is a small comfort to share some things about this boy who was on his way to becoming a wonderful man,” Sweeney wrote.

Sweeney described her son as an “old soul who was sensitive and loving.

“Evan wrote me letters, the last of which he gave me on Mother’s Day that was so touching it made me both laugh and cry. He was special. He deserved a long life,” she said.
