Adam Aviles Jr, the ex-boyfriend of missing woman Katie Ferguson, has reached a plea agreement with prosecutors.
33-year-old Ferguson was last seen in Trumann, Arkansas on October 5, 2023. She disappeared while on a cross-country trip from Alabama to Wyoming with her Aviles and their two children.
Aviles was arrested in November 2023 after law enforcement found bullet holes and blood stained items inside his SUV. Some statements indicate Ferguson’s disappearance has been investigated as a homicide with Aviles as a suspect, however so far he’s only facing gun and ammo charges.
The specifics of the plea deal have not been made public, as the US District Court in Wyoming chose to seal them.
With the gun and ammo charges Aviles could face anywhere between 0-30 years in prison. He remains in federal custody as he awaits further proceedings in his case.

The Disappearance of Katie Ferguson

In early October, Katheryn Ferguson and her two daughters left her mother’s home in Alabama after Aviles came to pick them up to make the cross-country trip back to his home in Cody, Wyoming.
Around 11:00 am on October 5, 2023, Ferguson was last seen by police during a routine check while in Aviles’ vehicle in Trumann, Arkansas. The family was resting in the parking lot of a gas station at the time.
The vehicle was again pulled over by Texas State Patrol on October 9 and by Colorado State Patrol on October 11.
Katheryn Ferguson was nowhere to be seen in the vehicle during the later stops, and a large pile of clothes was on the passenger seat instead. Bodycam footage also captured a projectile hole in the passenger door concealed with duct tape.
Katheryn Ferguson never made it back to Cody, Wyoming with Aviles and their children.
On November 2, 2023, her mother filed a missing person’s report with the Cody Police Department when she couldn’t contact her.
Investigation
On November 4, 2023, Aviles’ vehicle, a 1999 Black Dodge Durango, was found abandoned in the Oregon Basin area near Cody, Wyoming. The car was allegedly hidden with trash bags and smelled of “putrefied blood.”
Authorities found dry blood, a loaded Glock magazine near the center console, and a “projectile hole” in the front passenger door of the vehicle. The passenger seat was missing and cleaning wipes were found inside.
On November 13, 2023, 26-year-old Adam Shane Aviles Jr. was arrested on a possession of ammunition charge. He pleaded not guilty and his trial has been set for January 22th.
Adam Shane Aviles Jr. maintains his innocence in Katheryn Ferguson’s disappearance. He told police that Ferguson went on a “drug run” in Little Rock, Arkansas during their trip and did not return, leaving him and their two children.
