A body believed to be that of a man missing in Oklahoma since September was recovered Thursday and his boss has been charged with his murder.
New court documents filed in Logan County Monday detail how a family member of Brent Mack, 50, reported him missing on Sept. 28. The reporting party told Guthrie police that no one had seen or heard from Mack since Sept. 20. That person reportedly contacted Mack’s boss, Dan Triplett, 66, who operated a septic tank installation business.

Officers allege Triplett killed Mack on a work site. According to the police investigation, Triplett fired Mack on Sept. 20 and gave him $1,000 severance. Triplett told investigators he then dropped Mack off at a laundromat in Guthrie.
However, in the surveillance video outside the laundromat on Sept. 20, Triplett’s truck is seen driving by but not stopping.
Early in the investigation, Triplett reportedly said he wanted to cut ties with Mack because of his violent demeanor. When asked about what job had been completed on Sept. 20, Triplett gave an address north of Crescent. However, the property owner told agents the septic tank and lateral lines installed by Triplett had been completed on Sept. 8.
The property owner, according to court documents, added that a Black male subject was also working with Triplett and remembered the two men arguing.
After acquiring a search warrant for Triplett’s home and vehicle, investigators found a logbook of job locations. They found a record that showed Triplett had installed a septic system in Mulhall on Sept. 20, the same day Mack was last seen.
The people who lived in the home in Mulhall had surveillance footage of Mack and Triplett working on the job site. Investigators say Mack disappeared from view of the camera when he went down into the hole that was being dug for the placement of the septic tank. Police noted he was never seen in the footage again after disappearing into the hole.
Footage also showed two people arriving at the worksite, but only one person was seen leaving.
Investigators dug up the septic tank on Oct. 21. Underneath the septic tank, state anthropologists used a probe to find the body. Once the body was exhumed, investigators found a wallet with Mack’s ID inside.
Court documents show the medical examiner’s office located a projectile in the chest cavity of Mack with an entry wound in the upper-left back.
Triplett was arrested on Oct. 21. He was charged with murder and desecration of a human corpse. His next court date is Nov. 18.
