Family members of the missing Scripps Ranch grandfather joined search volunteers and neighbors for a memorial of hope Wednesday night.
They gathered at the West Sycamore Trailhead of Mission Trails Park, where Tai Sun was last spotted on a security camera.
Tai Sun walked the neighborhood daily so it was no surprise to see him hiking past nearby security camera in the early morning of June 15.
Two weeks later, there's been no trace of him.
Sun suffers from Alzheimer's and depression, his family said. He also speaks very little English.
Family members and friends are holding out hope he is safe somewhere but are preparing themselves for the worst.
With heavy hearts, the Scripps Ranch community came together one more time to show support for Tai Sun's family.

Karen Sun was most impressed with the community response to her missing father. Hundreds of people volunteered to help.
"My feeling here is very mixed. It’s very sad for the family of mine. I also see the beauty, the compassion showing through," Sun’s daughter Karen said.
Sue Melnyk and the "Ladies of Stonebridge" kept the search updates going on Facebook.
"I'm just so sad when I saw his family tonight," Melnyk said.
Others walked the neighborhoods, handing out flyers and searching for clues.
"This becomes something that is very personal to all of us living in this area. There must be an explanation. Whatever it may be. We need to know,” family friend Mike Lau said.
Tai Sun retired after years of working in the Taiwan fishing industry. He walked three to five miles a day and stayed mentally sharp by fixing electronic equipment as a hobby.
"I wish he's somewhere being picked up by a nice guy hopefully somewhere,” Karen Sun said.
The family and community hang on to hope but won't be satisfied without answers.
"As long as we can find him whatever the condition - the very best or the very worst - at least we'll find him and have closure," Karen said.
The Scripps Ranch Civic Association organized the searches and Wednesday’s event.
San Diego Police will continue to follow leads. San Diego County Sheriff's Deputies plan to perform periodic searches of the area by mountain bike.
