Ten-year-old Amberly Mendoza vanished from the Mendoza family home in Yuma, Arizona after a neighborhood barbecue on the night of March 8, 1996. She went to bed about 11:30 p.m. with her bedroom window left slightly open, a routine she and her sisters followed. The next morning her mother found Amberly dead in bed; investigators determined she had been sexually assaulted and asphyxiated with her own pillow. An unknown person is believed to have entered through the open window sometime between 11:30 p.m. and 10:45 a.m.

No signs of forced entry were found, but investigators recovered DNA that cleared family members and has been run through national databases periodically without producing a public match. Amberly’s sister later recalled seeing men outside the family’s window in the weeks before the killing. The Yuma Police Department keeps the case active; no suspects have been publicly named and no arrests have been announced.

Did anyone in Yuma at the time remember unusual activity near the Mendoza home or persons seen loitering near children’s bedrooms?
