Forty-one-year-old Denise Thiem went missing in early April while she was hiking a famous trail through Spain. She called her brother the day before Easter. Now he says he hasn't heard from her since.
Thiem had just started her journey on El Camino Santiago, an ancient pilgrimage route through Spain. Her solo hike was supposed to take about a month.
"The original plan was that we were supposed to do it together," said Thiem's brother, Cedric.
But Cedric stayed behind to take care of their dogs in Litchfield Park. Now her family is desperate to find out what happened to her. Her brother says she went on the journey to find more balance in her life. He never imagined that she wouldn't return from the trip.
"Some people suggested maybe she found somebody and just went away with him," said Cedric. "There were a lot of theories in the beginning. It didn't make sense."
Spain's National Police and the U.S. Embassy in Spain are working on the missing person's case. A missing person's flyer says Thiem was last seen Easter Sunday around noon in northwest Spain.
Back home, friends and family are trying to spread the word online about Thiem's disappearance, hoping someone has information that could help bring her home to Arizona.
"The biggest hope is that she would be found safe and that she would come back home," said Cedric.
