A woman is still in critical condition after a fire at a Las Vegas auto repair shop near Valley View Blvd and Twain Avenue. Authorities spent hours on scene Tuesday investigating what caused the fire that destroyed three cars and much of the garage at Midnight Motors Auto Repair. The auto-repair shop sits alongside several other businesses specializing in the same kind of repair. Workers say the entire area filled with smoke while some shops were forced to close early. "A lot of other shops on the other side, those guys did get a lot of smoke and a lot of the guys who were walking through the back entrance ended up getting evacuated," said Daison Orozco with a repair shop named Vegas HID.
