TULSA, Okla. (KTUL) — A missing persons case out of Turley has taken an interesting turn.
Dwayne Selby, 59, and 76-year-old, Jack Grimes, haven't been seen or heard from since last week.
A Silver Alert was issued for Grimes because he uses insulin to manage his health, according to Casey Roebuck, Tulsa County Sheriff's Office communications director.
Now, Selby's mother, 80-year-old Glenda "Cookie" Parton, has gone missing, too.
A Silver Alert was issued for Parton by the Pryor Creek police, but TCSO said because she went missing in Tulsa County, they are handling both investigations.
The family said the men live in Turley and they should've left Friday to travel to a horse show in Fort Worth.
"They were scheduled to return to Tulsa County on Monday and never arrived," Roebuck said.
Carol Selby, Dewayne's sister-in-law, told NewsChannel 8 the two men never made it to Fort Worth either.
"One of the horse trainers that they work without of the Fort Worth area called Dwayne Selby's mother, Glenda Parton, and told her that they never showed up for the show," Carol Selby said.
Parton went searching for her son on Monday evening near his home in Turley, according to family.
"Her car was found on 75 highway near the 56th street exit," Carol Selby said.
"We have been looking in that area but haven't found any evidence of her at this point," Roebuck said.
On Wednesday evening, the Tulsa County Sheriff's Office released new security camera photos from a local business that were taken right before she disappeared.
Pictured is Parton and a man the Sheriff's Office said is now a person of interest.
The family told NewsChannel 8 that the man seen with Parton is a ranch hand.
"Obviously a very strange turn of events. We don't know where any of the three of them are," Roebuck said, "So it's too soon to know at this point are these cases connected or are they completely separate from one another. We kind of have to look at all the possibilities right now."
In the meantime, the Sheriff's Office is asking anyone with tips on the person of interest, Parton, Dwayne Selby, or Grimes to give them a call at 918-596-5600.
