Corrine Leanne Erstad was five years old when she disappeared from a park in Inver Grove Heights, Minnesota, on June 1, 1992. She was last seen at about 7:30 p.m. wearing a white sundress with a pastel pink-and-green watermelon slice print. Two hours later her family reported her missing after she failed to return from the nearby park.

An unconfirmed sighting by another child described a girl matching Corrine’s appearance talking to an unidentified man who had a dog. Police quickly focused on Robert Guevara, a friend and frequent overnight guest in the family home. Corrine’s mother later told police Corrine had accused Guevara of molesting her on the day she vanished. Investigators reported canine tracking to Guevara’s residence and said they found a dress like Corrine’s and a pair of girl’s underpants with blood and semen in his work locker, and a stained shower curtain in his trailer. Guevara was arrested and tried, but acquitted. Corrine was declared dead in 1994 and her body has never been found.

What information do readers have that could help clarify Corrine’s last known movements or the people she was seen with that evening?
