I hear this one the radio so started researching it.

Selected parts of the article:
"Jennifer Frieling, 40, of Castle Rock, at 7 p.m. Oct. 28, was sewing a daughter’s Halloween costume when she heard an airplane engine that “sounded way too close.”
“I started getting up — and heard a boom,” she said.
She said out there in the fog, she could only see about 5 to 10 feet ahead of her, but soon spotted, down in the ravine, broken branches and then the plane’s red tail wing. And at 7:08 p.m. she called 911, again, to report a downed plane.
Morales said the pilot had planned to land at Front Range Airport in Adams County, but because of icing problems radioed Centennial Airport and was on her way to land there when she hit the major north-south power lines that are about 100 to 150 feet above the ravine."
Path/flight info from FlightAware
Weather info from the Front Range airport:
METAR/SPECI from KFTG, Denver Nexrad (United States). SA 28/10/2013 21:50

What this shows is that at 350 PM local, the weather at the destination airport had 1/2 statute mile visibility, fog, overcast clouds at 200 feet and the temperature and due point were both 0 degrees C. That info should have been available prior to take-off around 543 PM.
Weather info from the alternate airport at Centennial:

Also not desirable from my point of view. Both airports have conditions could be conducive to fog and possibly freezing conditions.
The flight altitude suggests that the pilot is instrument rated but I doubt that the plane is approved for flight in icing conditions.
Sometimes it is better to avoid a flight. Get-there-itis can end up badly. We shall see what the official NTSB analysis reveals.
