and Exploited Children in late 1999, at which point an image of how Mary might have looked at the time was developed. This age-progressed image depicted her at age 31. Sherrie Calgaro spoke to police regarding Mary's disappearance and an official investigation was opened in 2002. Her family were the only ones who knew about her disappearance; their neighbors were unable to recall them and did not recognize pictures of Mary, who had not been enrolled in school while living in Seaside. Kathy was able to give a more detailed account of the night of Mary Day's disappearance. She and Mary stayed home while William, Charlotte, and their two siblings went out to dinner.
