Two people were killed and two others injured Thursday in a residential fire in Las Vegas, Nevada.
The fire broke out just before midnight, according to a news report from the local CBS affiliate (http://bit.ly/15X15On).
When firefighters arrived on scene, they found the owners of the home, two people in their 60s, standing outside. Another couple was still reportedly inside--the owners had assumed the other victims were following them out. The owners were hospitalized for burns and smoke inhalation.
Investigators found the remains of the second couple inside the home.
Investigators say they suspect it might have started in the attic, which concealed the fire long enough to cause significant damage before crews arrived.
