Robert walked away from a nursing home in Castle Rock, Colorado under his own power. He told a nurse that he was going outside to smoke and never came back into the building. He did not tell anyone where he was going and does not have access to money. He does not have a cell phone. He speaks well and is intelligent but is in need of his medication. He may not present to the public that he is at-risk. He was spotted at a grocery store near the nursing home attempting to purchase cigarettes. He left the grocery store on foot and hasn't been seen since.
