Both were found in Northern Arizona Monday afternoon.
Cassidy Hayes left with Michael Malloch Jr. from Cathedral City, Calif., around 6 a.m. on Sunday.
Authorities say Malloch wrote a suicidal letter saying he cannot live without "her." He has since been taken into custody.
The two were spotted at a gas station in Munds Park, Ariz., on Monday at 9:15 a.m.
Hayes is described as 5'03", 115 Lbs., hazel eyes and red hair, however, it appears her hair has been dyed a dark color, according to recent video footage.
Malloch is described as a while male adult, 5'10", 165 Lbs., brown eyes and brown hair. He is believed to be driving a 2002 gold Subaru Legacy with California plate- 7HYS582.
