Chilling 911 calls from slain NC family home

RALEIGH -- Police have released 911 recordings that contain the sounds of a gunshot and a relative pleading for ambulances to get to the scene of a quadruple murder-suicide in Fayetteville earlier this week.

On one, a voice can be heard quietly moaning before the sound of a shot. A 911 operator tries in vain to get someone to speak.

On the second recording, a relative urges police and ambulances to get to the house. The relative says he can see blood and bodies, but he can't get inside.

In the background, a woman can be heard wailing, "I knew it. I knew it."

Authorities say William Maxwell killed his wife and two teen children before shooting himself Monday night. Friends say Maxwell's behavior changed in the weeks before the shootings.
