The father of missing 2-year-old boy, Sky Metawala, said he plans to work with volunteers today to pass out flyers with his son's picture on them.
Overnight, Solomon Metalwala met with reporters to plead for help in finding his son, who has now been missing for nearly a week.
"My hope is that he's coming back and that's where I find my strength, that he's going to come back," he said.
However, authorities also said that there's a "real possibility" that the 2-year-old may be dead, as growing suspicion is focusing on the boy's mother, Julia Biryukova, according to The Associated Press.
Biryukova told police she left Sky alone in her car after she ran out of gas and walked off for help.
Metalwala said Wednesday that he thinks Biryukova is connected with his son's disappearance.
"I do believe that Julia has a, she's responsible …," Metalwala said speaking of Biryukova. "It's sad. Because if she can just cooperate, we can find where, where is our son."
He also talked about a strange dream his wife had and which she related to him.
"In this dream she, she was strangling Sky," he said. "And it was very alarming."
Biryukova told detectives in Bellevue, Wash., that she was driving her two children to Overlake Hospital Medical Center Sunday morning because her youngest child, Sky, wasn't feeling well.
She said she ran out of gas on 112th Avenue, so she left Sky in the car while she and her 4-year-old daughter walked about a mile away to a gas station.
When she returned to her silver Acura SUV, the child was gone, she told police.
The boy hasn't been seen since.
Investigators have serious questions about Biryukova's story.
They say her account doesn't add up, and also say it's "strikingly similar in nature" to an episode of the TV series "Law and Order: SVU." The episode, which aired the night before Sky's disappearance, centered on a mother who tries to cover up the death of her child by saying he was taken from her car.
That detail also alarms Metalwala.
"'Law and Order' was Julia's favorite show and the similarities are pretty similar and if she got that idea in her head that 'I can make this happen,' she's not going to fear the consequences, because she doesn't fear consequences," he said.
According to police, Biryukova did walk to the Northtowne Chevron Service on Sunday, but she never bought gas there, police said.
Instead, she spent time walking around a wealthy neighborhood where she reportedly didn't ask anyone for help, officials said.
When detectives checked to see how much gas was left in her car, they found enough for her to have continued driving.
Investigators took her car for a test drive, to see if it had any mechanical problems that would have forced her to leave it on the side of the road.
Police said they are now convinced it didn't have engine trouble and there was plenty of gas in the tank.
"I'll let the evidence speak to itself, which is there was gas in the car and was able to drive and operate. That's not what Julia told us," Bellevue police Maj. Mike Johnson said.
Police said that after Biryukova visited the gas station she called a friend who picked her up and took her back to her two-door silver Acura, where they allegedly discovered the boy was missing.
Metalwala has agreed to take two polygraph tests, but Biryukova has refused to be tested, telling investigators that she has been too disturbed to participate.
