Since last Thursday, several law enforcement agencies have scoured the desert looking for 38-year-old Sarah Galloway who has Down syndrome.
Tad and Kandance Jaconski are Galloway's brother-in-law and sister, they say they don't understand why she suddenly disappeared.
"I've never seen her walk off by herself or even talk back or bad to anybody or argue with her mom in any bad way and very kind but always accept anything from anybody so that's what worries me."
Spokesperson with the Pima County Sheriff's Department, James Allerton, says multiple agencies have been searching for Galloway.
"The Department of Public Safety has sent air assets out here to assist us, the US Border Patrol has sent their search and rescue, their BORSTAR units as well as K-9s to assist in the search."
The sheriff's department says the search has been challenging because of the open terrain and not knowing Galloway's motivation.
Deputies have been going back to neighbors, asking them to check their property.
The Jaconski's say they'll never be able to find peace if Galloway is not found.
"She's gone and we can't find her and we're still looking, we're not going to give up and we're begging people to bring her home."
