Note to self: when someone is screaming, "I'm gonna kill you", don't open the door and try to have a conversation with them. http://espn.go.com/nfl/story/_/id/1...ills-tight-end-buster-barnett-kills-wife-self Ex-Bills tight end Buster Barnett's mistress kills his wife, then herself ATLANTA -- A former NFL player's mistress, apparently jealous he was taking his wife on a trip to Las Vegas, drove to his home near Atlanta, kidnapped her romantic rival and then led officers into Alabama on a chase before killing the wife and herself, police said. Lisa Brown, 46, showed up at the workplace of former Buffalo Bills tight end Buster Barnett on the morning of July 15 and was upset about the planned trip, Clayton County police spokeswoman Charlene Watson-Fraser said. Brown then went to Barnett's home in Ellenwood, Georgia, and abducted his wife, 50-year-old Sandra Barnett. Buster Barnett, drafted in the 11th round in 1981, played for the Bills from 1981 to '84. George Rose/Getty Images Ruby Chester, a longtime friend of Sandra Barnett, said she was on the phone with Sandra at around 11:20 a.m. July 15 when there was a knock on Barnett's door. Chester told The Associated Press she could hear a woman's voice yelling, "Open this door! Open this door, or I'm going to kill you!" Chester said she heard Barnett talking to the woman: "Don't hurt me, ma'am! I don't know you!" Then she asked, "Are you Lisa Brown?" Chester said she and Sandra Barnett had known each other for 10 years and kept no secrets, so Chester knew Buster Barnett, who she said is now an Atlanta schoolteacher, had been involved in an affair with a woman named Lisa Brown. Chester said Brown had harassed her close friend for at least a couple years while Barnett tried to keep her marriage together. Buster Barnett, selected by Buffalo out of Jackson State in the 11th round of the 1981 draft, played for the Bills from 1981 to '84. "Lisa Brown had been aggressive toward Barnett and had been bothering Barnett off and on for some time -- showing up at the house, texting her, calling her," Chester said. But her friend would never do anything about it and left it for her husband to handle, Chester said. Chester tried calling police the day of her last phone call with Sandra Barnett, but she wasn't in the same county, so she didn't get connected to the correct police department, she later told an officer, according to a police report. She then called Gerald Payton, a friend and coworker, and asked him to drive by the Barnetts' home. When Payton arrived, he saw a black Dodge Durango parked in front of the home and a woman in the garage, he told police. He wrote down the tag number on the SUV, called 911 and drove around the corner to wait for police. Before officers arrived, he saw the SUV drive by but couldn't tell if Barnett was in it, the police report said. Payton tried calling Barnett several times but kept getting her voicemail. Sandra Barnett's brother, John Brooks, told police the vehicle belonged to his sister's husband's "ex-girlfriend and that she had some issues," the police report said. Clayton County police put out a lookout on the Durango. Sheriff's deputies in west Georgia saw the vehicle the next morning and chased it along Interstate 20 into Alabama, police said. The SUV stopped at mile marker 208 on a stretch of the highway in Cleburne County, Alabama, and a standoff ensued, Alabama Law Enforcement Agency spokesman Steve Jarrett said last week in an emailed statement. Police said Brown then reached into the backseat of the SUV, grabbed a gun and shot Sandra Barnett before shooting herself. Both women were dead when officers got to the SUV, authorities said. Watson-Fraser said she didn't know where the two women were between the time of the abduction late on the morning of July 15 and when authorities spotted them the next day. Buster Barnett told police he and Brown were in a relationship. He owned her home and vehicle and told police he was "helping her out," Watson-Fraser said.
