Family searches for missing son OAK RIDGE, Tenn. ? "We just want him found.? Those are the words of Tricia Funk, whose 19-year-old son Derek Ryan Funk disappeared last week. Derek left a woman's house in Powell about midnight May 12, but never arrived at his South Knoxville home. His parents, long-time Oak Ridge resident Kevin and Tricia Funk, are "terribly worried" about their son. Knoxville Police Department spokesman Darrell DeBusk said a missing persons report was filed with the Knoxville Police Department last Thursday. Derek was on the phone with the Powell woman for about 16 minutes, his mother said. That was believed to be the last anyone has heard from him. He didn't arrive home and he failed to show up for work on Thursday. "He loved his job," his mother said of Derek's work at East Tennessee Railroad in Oak Ridge. He has worked for the company for two years. "When he didn't show up for work, we knew something was wrong," Tricia said Tuesday. Tricia said Derek moved to South Knoxville in April. When Derek didn't show up at work, his mother called all of his friends and then the Knoxville Police Department. "They can't even find his truck," she said. The 2009 Oak Ridge High School graduate drives a white 1996 Ford Ranger pickup truck. He is 5 feet, 11 inches tall and weighs about 130 pounds. He has blond hair and blue eyes. Tricia said her son also has several tattoos on his body, including both arms. "There's been no contact since that midnight phone call," Tricia said. "His phone goes straight to voice mail." Tricia also said her son carried bank cards, but there's been no activity on the cards. A Knoxville television station's news story reported that Derek had been "severely depressed," but his mother said that was not the case. "He has been under stress but not medically depressed," she said. "He talked to us about it." She also said her husband talked to Derek earlier on May 12. He had ate dinner with the family, including extended family members, on May 11. "This is not like Derek," his mother said. "We fear something is wrong." Anyone with information about Derek should call the Knoxville Police Department's Crime Information Line at (865) 215-7212, or 911. Beverly Majors can be contacted at (865) 220-5514.
