-- The FBI has been called in to assist in the delicate search of a remote area in Cass County, where human bones were found Monday evening by a mushroom hunter, and now remains of a second person have been found nearby in the area on Tuesday. Authorities with Cass County now say they have found a second human skull in the wooded area near E. 233rd and State Route Y, south of Belton, where they found the first human skull on Monday. They also say they have been in contact with the families of Kara Koptesky and Jessica Runions, two young women missing from the Kansas City area, but could not confirm if the remains were that of these missing women. The Missouri State Highway Patrol has shut down approximately 6.5 miles of S. State Route Y between YY-Hwy and D-Hwy (Holmes Road) for the search. The Cass County Sheriff's Office said they will continue searching the wooded area for at least the next 2 days. The families of Kara Kopetsky and Jessica Runions were notified Monday evening about the discovery of unidentified skeletal remains. Kopetsky was last seen leaving Belton High School on May 4, 2007 and has not been seen since. Runions was last seen at a party Sept. 8, 2016 with her boyfriend and one of his friends, Kylr Yust. "We're another day closer to getting answers, and you know, every hour, every day, every minute, we just hope and pray that those answers come in and we finally, you know, find our daughters, and we're able to put the dirt bag away for the rest of his life so he can never hurt anybody ever again," said Kopetsky’s mother, Rhonda Beckford.

 Runions’ SUV was found burned along Blue River Road in south Kansas City shortly after she vanished. He has been charged in Jackson County with 'knowingly burning' in connection to Jessica Runions' case and car. A police report taken after Kopetsky's disappearance shows a witness told police they saw the vehicle belonging to Kylr Yust, Kopetsky's ex-boyfriend, in the area where Cass County authorities say those remains were located.

– The families of two missing women have been notified after the discovery of a pair of skulls this week outside Kansas City, the Kansas City Star reports. Kara Kopetsky was last seen in 2007; Jessica Runions disappeared last September. Neither woman's body has ever been found. The first skull was discovered by a mushroom hunter Monday in a wooded area of Cass County. According to WDAF, authorities found the second skull Tuesday while searching the area. A number of other bones have also been found. While the families of Kopetsky and Runions were notified, neither of the skulls has been identified yet, KMBC reports. It's unclear how long it could take to get an identification. The families of the missing women are hopeful the remains will soon provide some answers. "Even if it’s not Kara, it’s someone’s loved one and someone has answers,” Kopetsky's mother tells the Star. “Good or bad, someone has answers.” Runions' family has been searching regularly since her disappearance. Searchers found two bodies in January, neither of them belonging to the missing women. Runions, 21, was last seen leaving a party with 28-year-old Kylr Yust, a friend of her boyfriend, in September. Yust has been charged with burning her car after it was later found. Yust had dated Kopetsky prior to her disappearance at the age of 17 a decade ago. Shortly before she went missing, Kopetsky filed a restraining order against him.
