Almost one week exactly. That's how long Mary O'Sullivan Schultz, an Alzheimer's patient from Mesa, has been missing.
On Wednesday, her daughter and friends arranged the most extensive search for her yet.
"My mom has two grandkids. We want closure," Schultz's daughter Leigh Schultz, said.
Volunteers divided into six groups and canvassed from Stapley Drive and Main Street to Ellsworth and Brown roads.
Some were on ATVs, others were on foot handing out flyers. An estimated 100 volunteers showed up.
Schultz was barefoot and without her medication when she left her personal care facility near Broadway and Higley roads on Thursday morning at around 2 a.m.
Her daughter said most of the volunteers who came out to help were strangers.
"Most of my family is in Ireland so they're like we can't be there. I have people (searching) I didn't even know that I had," Leigh Schultz said.
Schultz was known to walk long distances. She did not take her shoes, glasses, dentures or medication with her. Her daughter is asking everyone in the Mesa area to look in their sheds and backyards because she may have tried to find shelter from the heat.
