It's been more than seven years since a Bardstown mother of five vanished and to this day, it still remains a mystery.And the efforts to figure out what happened to Crystal Rogers haven't slowed down.In fact, the FBI was just back in Bardstown last week for a new search. Agents spent days looking for clues and have since wrapped up.Here's everything we learnedLast week's search was focused on the farm where Rogers was last seen alive.The farm is on Paschal Ballard Lane and belongs to the family of Brooks Houck, Rogers' boyfriend and the prime suspect in the case.Investigators were there from Monday to Friday. The farm is 200 acres, but they were focused on a smaller portion of it.They had drones, cadaver dogs and excavating equipment at the scene.At the end of the search, the FBI said evidence was collected."We hope that the evidence collected will move our investigation one step closer to holding accountable the individual(s) responsible for Crystal Rogers' disappearance," said Special Agent Jodi Cohen.However, they did not specify what that evidence was. It is being sent to a lab in Quantico.The farm was also searched extensively in 2016. Then, the FBI, Jefferson County Sheriff맥스카지노�s Office and Louisville Metro Police Department all helped Nelson County officials search hundreds of acres, including through water, caves and brush.

The FBI took over in 2021, and spent multiple days in a totally different area: the Woodlawn Springs subdivision.That's where Houck had been building homes at the time of Rogers' disappearance.They were looking at three homes, and then honed in on one -- which he built but no longer owns.Then, agents said they found two items of interest that were sent to a lab in Quantico, but never disclosed what they were.In 2020, more than 150 state and federal law enforcement officers were deployed to Bardstown and on the first day, they executed at least nine federal search warrants and conducted more than 50 interviews.One of the searches was at Houck's home. They also searched his brother's home (Nick Houck) and family farm -- the one that is the focus of the latest search.More background on the caseRogers was reported missing on July 5, 2015 when she was 35 years old. Her car was found that day abandoned with a flat tire on Bluegrass Parkway in Bardstown with her phone, purse and keys still inside.She had five children, one with Houck. While he is the only person since she disappeared to be named as a suspect, he has never been charged. Houck's grandmother, Anna Whitesides, has been connected to the case, as well. The state said back in 2016 that they believed her car was used to dispose of Rogers' body. She refused to testify when called to court.Within the first year of Rogers' disappearance, Brooks' brother, Nick Houck, was fired from the Bardstown Police Department for interfering with the investigation.Early on, a friend and employee of Brooks Houck, Danny Singleton, faced 38 counts of perjury for lying to detectives during the investigation, but pleaded guilty to lesser charges of false swearing.Rogers' father, Tommy Ballard, was killed while hunting the year after her disappearance. His killing also has not been solved. What's next?That remains unclear. Evidence collected will be tested, but beyond that, the FBI hasn't said if or when they'll return to Bardstown.In 2020, officials launched a website dedicated to her case. Some updates can be found there.
