BELLEVUE, Wash. -- Thursday, November 6th marked three years since Sky Metalwala disappeared in Bellevue. He was just two years old at the time.
His mother told investigators she left him in a car when she ran out of gas, and he was gone when she came back.
Investigators eventually found out the car had plenty of gas.
Sky's mother was never charged with a crime, but police did consider her a person of interest.
"Maybe there's someone out there that saw something at the time of the story, three years ago, they didn't think much of it, but now looking back, maybe they think that information would help us," said Bellevue police officer Seth Tyler. "We'd really like to hear from anyone that has any information."

Over the years, detectives have dug into the more than 2,500 tips they've received. But in the last year, they've received only two tips.
