Crime Mother-of-Five Missing for 10 Days; Family Casts Suspicions on Boyfriend Crystal Rogers, 35, was last seen on July 3 by her live-in boyfriend Brooks Houck By Tara Fowler Published on July 13, 2015 10:10 AM Share Tweet Pin Email The sister of a missing mother of five has said that she’s suspicious of the woman’s live-in boyfriend – and the last person to see her alive. Crystal Rogers, 35, went missing on July 3. Her boyfriend Brooks Houck said that she stayed up late that night, but was gone from their shared Bardstown, Kentucky, home when he woke up the next morning. Two days passed before he officially reported her as missing, Fox News reports. “The stories just don’t add up,” Rogers’ sister Brooke Ballard told ABC News. “You just don’t go to bed one night and not know she’s gone and then not worry when she left the baby.” The couple has a 2-year-old son together. The other four kids are not Houck’s biological children. “He has not offered once to search – or help – or do anything for the family,” Ballard added. Houck has denied any involvement in Rogers’ disappearance, even taking a lie detector test. The results were inconclusive. “I’m 100 percent completely innocent in this,” he told Nancy Grace on HLN, adding that he has indeed been helping with the search, though his efforts have been “behind the scenes.” “I want the emphasis to remain on Crystal’s safe return,” he added. Police have not named a suspect or even a person of interest in the case. ABC US News | World News The only clue thus far in Rogers’ disappearance is her car. Police found the mom’s maroon Chevy Impala with a flat tire on July 6 near the Bluegrass Parkway. Her purse, keys and cellphone were inside. Police are asking anyone with information on Rogers’ disappearance to call the sheriff’s office at 502-348-1840. A total of $71,000 in reward money is being offered for information that leads to her return. Want to keep up with the latest crime coverage?
