Oceanside police are asking agencies in California, Arizona and Nevada to be on the lookout for an elderly man who has been missing since last Thursday.
Nicholaos Christidis, 76, was last seen by his daughter at 10 a.m. on July 22, when he returned home with her.
She laid down take a nap, but as she awoke at about 4 p.m., she found a note from her father, saying he would be home late, according to police. The next day at 8:26 a.m., Christidis accepted a call from his ex-wife and said he was in Escondido. He told her he would return home in 15 minutes.
But by 10:35 a.m., he had not returned, so his daughter gave him a call. Christidis said he was in the desert and would be home in an hour. When his daughter called him again at about 4 p.m. on July 23, Christidis’ cellphone went straight to voice mail.
Now, nearly a week later, his cellphone is still turned off, his car has not been found and no one has heard from him.
"His community wants him back," said neighbor Monica Mosack. "So if people could keep their eyes out for his car, keep their eyes out for him, it would really be appreciated by our neighborhood."
Christidis is a white man of Greek descent who stands 5-feet-7-inches and weighs 175 pounds. He has gray hair and brown eyes.
Officials say he was last seen on July 22 at 10 a.m. near College Boulevard and State Route 78 in Oceanside. He is driving a black, 2015 Honda Civic with the California license plate of 7JYR793.
Oceanside investigators issued a silver alert across three states so law enforcement and other facilities like hospitals and park rangers will look for him.
According to police, Christidis has gotten lost on numerous occasions, and in one incident, he ended up in Arizona. Investigators say he has not been clinically diagnosed with Alzheimer’s or dementia and does not suffer from any medical conditions.
Neighbors are hoping for Christidis' safe return.
"This is a really good man and a good neighbor," said Mosack. "He's not just a quiet neighbor who doesn't cause problems, he is actively helpful and actively considerate. And he's been living here for 39 years and his community wants him back."
Detectives say Christidis could be anywhere.
