Agents from the FBI, DCI and Poweshiek County Sheriff’s Office swarmed the workplace of Cristhian Rivera, the man charged in the murder of 20-year-old Mollie Tibbetts, early this morning, sources close to the investigation exclusively told RadarOnline.com.\n\n“This case is far from finished,” the source told RadarOnline.com, only on condition of anonymity as this is an ongoing investigation. “It appears there are more pieces to this puzzle – each day everyone learns something new about Cristhian Rivera – and the investigation will unravel all of the ghosts that he has in his closet.”This comes exactly two weeks after RadarOnline.com broke the news that agents from the FBI swarmed Rivera’s trailer with guns drawn immediately following the preliminary autopsy reports.\n\nAs RadarOnline.com readers know, Tibbetts was last seen jogging in her secluded hometown of Brooklyn, Iowa when she vanished. Tibbets was found dead in a cornfield just miles from where she was last seen.\n\nRivera, who went by ‘John Budd,’ was employed by Yarrabee Farms. He lived on their property and allegedly terrorized other women in the secluded town of Brooklyn, Iowa.According to an eyewitness, agents were searching through trailers, speaking with residents and farm workers about the abduction and brutal murder of the 20-year-old University of Iowa rising sophomore.\n\n“They asked us about the black Malibu and if others on the farm ever drove it,” a local employee told RadarOnline.com. “The questions were pretty generic, they didn’t ask about anyone’s legal status. They just wanted to know more about the black Malibu and Cristhian.”Sources close to the investigation told RadarOnline.com they are searching for other individuals who might’ve assisted, aided, abetted or had knowledge of what Rivera had done.\n\nAs of this morning, Rivera has yet to be charged with kidnapping and faces only one count of first degree murder.\n\nRivera is in custody at the Poweshiek County Jail in lieu of $5 million cash bond.\n\nWe pay for juicy info!
