When fire crews arrived to the scene of a mansion fire in Nichols Hills, they quickly called out several firefighters to battle the massive blaze caused by a lightning strike. "My patio door was pointed right toward the flash," said Ken Wyatt. "It was enough to wake you up." Fire officials say lightning hit the attic of a three-story mansion around 5 a.m. on Wednesday. "They say the alarm system did go off and alerted them to the smoke up in the attic," Chief Randy Cornelius, with the Oklahoma City Fire Department, said.
