FAYETTEVILLE, N.C. - 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 yesterday that 47-year-old Maxwell killed his wife, Kathryn, and their children, Connor, 17, and Cameron, 15, before shooting 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.

“They were just wonderful people,’’ said Kay Edwards, who has lived next door to the Maxwells since 1994. “They were just good neighbors.’’

Edwards said she would often see family members walking their small dog through the quiet, leafy neighborhood.
