Police have charged a 15-year-old boy with shooting his father and stepmother to death early Monday inside their home near Pineville. Charlotte-Mecklenburg police say the suspect, whose name has not been released because he is a minor, also is charged with armed robbery and attempted auto theft. Dead are Christian Hans Liewald, 43, and Cassie Meghan Buckaloo, 24. Their bodies were found by police shortly after 2 a.m., after Liewald's son called police and told them he had killed the couple, according to investigators. The victims lived at a house in the 12300 block of Buxton Drive, off Lancaster Highway in southern Mecklenburg County. Liewald and Buckaloo were listed as staff members at Zoar United Methodist Church in southwest Charlotte. According to the church's directory, they were in charge of the website. Christian Liewald's Facebook page says he was a Fort Mill High School graduate who attended CPCC. Zoar United Methodist's pastor, the Rev. Marilyn Smith, could not be reached. Neighbors said there were no signs of domestic trouble at the residence, but several neighbors said Christian Liewald had a history of arguments with neighbors. Police say someone, apparently the 15-year-old, called 911 around 2 a.m. Monday and asked to speak with a police officer. The caller hung up, police say, then called back a short time later. This time, according to police, the caller said he had shot his father and stepmother, and he asked officers to go to the house. The caller also told police he would be sitting on a nearby street corner, waiting for them. Officers found the 15-year-old on Rudolph Place Drive, about three-quarters of a mile from the shooting scene. Other officers went to the Buxton Drive address and found the victims, who were dead. According to police, someone called 911 shortly after 2 a.m. and said he needed to talk with police but didn't say why. A short time later, police say, the same person called 911 again, said he had shot his father and stepmother, and said he would be sitting on a nearby street corner, waiting for police. Police cordoned off the murder scene, but neighbors gathered throughout the morning hours Monday, talking to reporters about the victims. None of the neighbors recalled any signs of domestic disputes. One neighbor, Greg Hicks, told Observer news partner NewsChannel 36 he was surprised to see the 15-year-old charged. "Something had to push him to do something like that," Hicks told WCNC. "Because he's really a great kid." Some neighbors told stories of having problems with Christian Liewald. "He carried a gun, and it frightened some of us," said one woman, asking that her name not be used. Hicks said he was shot and wounded by Liewald several years ago during a dispute. Court records show Liewald was charged in June 2007 with assault with a deadly weapon, but the charges later were dismissed. Another neighbor, Amy Taylor, told NewsChannel 36 that she heard the shooting. "I heard three, four, five ... maybe even six shots fired," Taylor told WCNC. She said that a short time later, police cars arrived.
