PEA RIDGE, Ar. (KY3) - Pea Ridge, Arkansas, is rich in history — a quaint but growing community where, in 2006, about 3,000 people lived, and crime was low. That sense of small-town safety was shattered nearly 20 years ago, when 15-year-old April Dawn Andrews vanished and was never found. Benton County sheriff’s investigators say it remains their largest unsolved case and the one that still “continues to come up.” Family members remember Andrews as quiet, sweet, and timid.
