Arsenal found in home of defriending murder suspect NASHVILLE, Tennessee (Reuters) - Authorities investigating a double murder in Tennessee believed to have been sparked by a Facebook "defriending" have discovered an arsenal of handguns in the home of one of the two suspects. Investigators had recovered "like 80-some handguns" from the home of Marvin Enoch Potter Jr., who is scheduled to be arraigned on Wednesday on suspicion of playing a role in the killings, Johnson County Sheriff Mike Reece said on Tuesday. "It looks like we've not found the actual murder weapon yet," Reece said. Authorities in the rural community in northeast Tennessee say Billy Clay Payne Jr. and Billie Jean Hayworth were killed last month after they deleted Jenelle Potter, Potter's daughter, from their "friends" list on the popular social network site. Both victims were shot in the head and Payne had his throat cut. The couple's 8-month-old baby was in found in Hayworth's arms, unharmed. Potter, 60, Jamie Lynn Curd, 38, appeared last Wednesday in court, charged with two counts of first-degree murder in connection with the killings. Potter's arraignment was postponed until this Wednesday because he wanted to hire his own attorney, said Assistant District Attorney Matthew Roark. Attorney H. Randolph Fallin said on Tuesday he had been retained to represent Potter and that he planned to enter a not guilty plea at Wednesday's arraignment before General Sessions Judge William Bliss Hawkins. She could not be reached for comment. County Mayor Larry Potter - no relation to the suspect - said people were "just devastated" by the case. "It makes you plum sick that things like this can happen," said Potter, who has spent all 56 of his years in Mountain City and Johnson County, with combined population of around 18,000. R.O. Smith, of the public defender's office, was appointed to defend Curd, who is being held on $1.5 million bond, awaiting the March 21 preliminary hearing set for both men. The sheriff said Jenelle Potter was constantly on Facebook and had in the past feuded with other friends on the site. "Once you've crossed her, you've crossed her father too," Reece said. Last year in Iowa, a woman was arrested on accusations of setting fire to a friend's garage after she was defriended on Facebook, local media reported. Reporting by James Kelleher and Daniel Trotta
