Bret-Jordan Kreiensieck isn't just looking at a highlighted Santa Clara County map; he sees a road map through his father in laws' life. It's a possible route that might lead to the missing 63-year-old man.
Ross Abinanti suffers from dementia. He was last seen leaving the Second Street Parking Garage on East Campbell Avenue last Tuesday night.
"When you have dementia or Alzheimer's your present memory may not be the most accurate, but your past memory may be crystal clear," says Kreiensieck.
On Friday the family shifted its focus to Abinanti's past. They think he may re-visit some of his old stomping grounds.
Once they pinpoint a new memory, a group then scours that area, putting up flyers and searching for the man, whose history may be guiding him.
The memories come rushing back for daughter Ally Abinanti, as she walks through the East San Jose neighborhood looking for her father.
"I'm trying to stay calm," says Ally.
However, more fear sets in as she goes from store to store asking for help.
Volunteers are sure Ross made a lot of memories on Alum Rock and White Road. He grew up just up the street and went to high school across the street. Regardless, there's still no sign him, even though Abinanti is wearing an emergency alert bracelet. It may be malfunctioning or he may be out of range of its receiver.
"It's definitely a concern, being gone for so long with his medical condition, the dementia, and just not being familiar with the area so we have concerns about his safety," said Campbell Police Sgt. Gary Berg.
Others as well are growing deeply concerned too.
Dementia affects so many people and their families. It is not a specific disease, but rather a collection of symptoms caused by disorders affecting the brain. Those causes include Alzheimer's Disease and brain tumors -- just to name two. Memory loss is not the only symptom; symptoms can also include erratic behavior and poor judgment.
