A woman from Mercer County goes missing after her son's first birthday. Did she leave without a trace or was she murdered? Brenda Lambert was a fun-loving and feisty woman, according to her sister. So why would she leave her children? Did her husband drive her away? The case is cold enough that we may never find out the answers to these questions, but it doesn't stop hope. Christy Kennedy, Brenda's Sister hasn't given up hope, even garnering the interest of national television and most recently: Crime in the Coalfields.
