New surveillance video released by San Diego police Wednesday may provide more clues to help in the search for a missing 85-year-old at-risk man in Scripps Ranch.
Taiheng Sun was last seen at his home around 7 a.m. Thursday on the 15000 block of Maple Grove Lane. When his family returned home after 7:32 p.m. that day, he was gone.
Nearly a week later, a surveillance image showed Sun walking alone into the West Sycamore Staging Area of Mission Trails Regional Park. The photo was taken more than an hour after his disappearance Thursday morning.
Sun suffers from Alzheimer's and depression, his family said. He also speaks very little English.
On Wednesday, police released a video that captured a man fitting Sun's description getting out a car on Legacy Canyon Place Saturday afternoon. The location is six miles from where Sun was last seen.
The video appears to show the man disoriented. He crosses the street and then comes back. After about 30 minutes, he started walking north on Legacy Canyon Place.
The car in the video is described to be either a beige or silver Ford Taurus.
Police said they are not positive the man in the video is Sun, but a woman who lives on the street said she saw him.
The video brought about 100 volunteers to Legacy Canyon Place to search for Sun, many scouring the area with their drones.
"I can see the horizon or I can look straight down below me,” drone operator Drew Goodwin said.
Volunteers on foot passed out missing person flyers door-to-door and asked residents for security camera recordings that might have captured images of Sun.
"It could be any one of us or any one of our relatives," neighbor Stephanie Runyon said.
Among the volunteers is San Diego Police (SDPD) Chief Shelley Zimmerman.
"A lot of my neighbors were out searching for Mr. Sun. I just wanted to come out here and make sure I myself show a lot of support," Zimmerman said.
"Every time there is new sighting and new information there is new hope,” Goodwin said.
Volunteers and authorities searching for Sun are also concerned about the heat wave sweeping through San Diego County.
The Scripps Ranch Civic Association president told NBC 7, Sun's disappearance is having an unexpected residual effect on the community.
He is hearing through social media about several instances where neighbors are reaching out to help the senior population in the community that might be having heat issues.
