RENO, Nev. -- Fire investigators in Reno say arcing power lines likely caused the wind-fueled wild fire that destroyed 15 homes and damaged at least 40 more.
Reno Fire Chief Mike Hernandez says the 2,000-acre fire is now 65 percent contained.
He expects that to climb to 90 percent or better by Sunday. Hernandez says the nearly 10,000 people who were evacuated on Friday can start to return to their homes.
Hernandez says there's no official cause yet, but all signs point to the power lines. He says investigators ruled out the possibility that teenage partiers or a homeless campfire was to blame.
