She has missed her 11th birthday party, the start of a new school year, holidays and family gatherings.
Investigators say they continue to hope a piece of critical information might be found that can bring the case to a close.
Undersheriff Rick Scott says there's a renewed search around McCleary, and the reward for information on Lindsey's whereabouts has risen to $30,000.
Also, new surveillance video has been released. Detectives want to talk to the men in the black plaid shirt, and red tank top.
They were in the area around the time Lindsey disappeared, and might have seen something.
