April 11, 2011, Federal Way, Washington. Police issued an AMBER Alert after an 8-year-old girl disappeared from a playground shortly after a man in his 20s was seen taking pictures of children at the playground. A short while later, a department store clerk noticed a man, wanting to buy clothes for a young girl, was acting strangely. The employee checked her iPhone AMBER Alert application and saw the man and child matched the description in the AMBER Alert. Store personnel called the police, who arrested Benjamin Trinh, 28, of Tacoma, Washington, and charged him with kidnapping.
