FAYETTEVILLE -- North Carolina police say a real estate developer known as an active member of his church shot and killed his wife and two teen children and then committed suicide in their Fayetteville home. Authorities did not hint at a motive into the slayings by William Maxwell in an upscale neighborhood of the city Monday night. Police said Tuesday that 47-year-old Maxwell killed wife Kathryn, 17-year-old Connor and 15-year-old Cameron before turning a gun on himself. Friends and neighbors say the Maxwells were a friendly family who kept a meticulous yard and were active in their church and their children's religious high school. Fayetteville is about 50 miles southwest of Raleigh and home to the Army's sprawling Fort Bragg. (Copyright 2009 by The Associated Press. All Rights Reserved.)
