When forest personnel discovered a woman wandering along a remote road south of Blue Mountain Lake in Yell County on Friday, her story set off an extensive ground and air search.
Brooke Floyd's husband and 10-month-old son were stuck in the Ouachita Mountains. Their truck had broken down.
By Monday, the Yell County sheriff's office located the truck that the Greenwood family was last seen driving in -- with help from the FBI, Arkansas State Police, U.S. Forest Service and other surrounding agencies, Sheriff Bill Gilkey announced at a news conference.
Its passengers, Brian Floyd, 31, and infant Harper Floyd, remain missing.
"The area is very treacherous, very mountainous," Gilkey said. "The truck was in a position that because of the foliage this year and the canopy of the trees, it was unable to be discovered by air. ... There's not a road to get where the truck is."
On Monday, the Yell County sheriff's office also confirmed that its deputies arrested Brooke Floyd, the missing infant's mother, saying she hindered apprehension or prosecution and endangered the welfare of a minor.
No affidavits or arrest warrants had been filed Monday in Yell County court.
"She was not being as cooperative with the investigation as she could have been," Gilkey said, before adding that her efforts Monday led to the discovery of the truck.
Investigators are still determining whether Brooke will be treated as a victim or suspect, Gilkey said.
Meanwhile, authorities will continue the search, and rescue dogs began working the area Monday.
In a separate incident last week, Brian Floyd was arrested by Sebastian County sheriff's deputies on a misdemeanor charge of communicating a false alarm.
According to the July 20 arrest report, Floyd had called the sheriff's office multiple times.
When officers arrived at his home, Floyd was in his truck and "appeared to be in a manic state and hallucinating," the document stated.
He reported that a woman had broken into his home and was driving around his residence and that police dressed in black with police dogs were on his roof.
Deputies contacted a family member, who said that Floyd had been having trouble with medication for his mental health.
Lt. Philip Pevehouse of the Sebastian County sheriff's office said that before that incident, he was not aware of any previous issues concerning Floyd.
A Facebook group called "Team Harper" was created Saturday to keep area residents updated on the case and to rally the community for help. As of Monday evening, 3,366 users had liked the page.
