Friends and family of 33-year-old Kassanndra Cantrell are extremely worried. The mom-to-be hasn't been seen in days and she missed her first sonogram appointment for her pregnancy. Her phone last pinged in Point Defiance Park, but her mom says that's not a location Cantrell is in normally. Cantrell was last seen via Ring doorbell camera video, leaving her home in her car. That car was found abandoned near the Tacoma Dome.Joining Nancy Grace today:Kathleen Murphy - North Carolina, Family Attorney, www.ncdomesticlaw.comDr. Angela Arnold - Psychiatrist, Atlanta Ga www.angelaarnoldmd.comInvestigator James Shelnutt - 27 years Atlanta Metro Major Case detective, SWAT Officer, Attorney www.shelnuttlawfirm.comNicole Partin - Crime Online Investigative ReporterTIP LINE - Pierce County Sheriff's department - (253) 798-7530
