The drummer for country music star Kellie Pickler was in serious condition Sunday as one of five people hospitalized in two crashes that happened within minutes at the same spot on Interstate 65 in central Kentucky and killed six.

Pickler’s manager, Larry Fitzgerald, said 36-year-old Gregg Lohman of Goodlettsville, Tenn., suffered serious injuries in the wreck Saturday. He remained in serious condition Sunday at University of Louisville Hospital.

Kentucky State Police Master Trooper Norm Chaffins said Lohman, who also works as a music instructor at Tennessee State University, had head and neck injuries after a four-vehicle wreck in the southbound lanes. It happened about 15 minutes after a fiery crash involving a tractor-trailer and an SUV on the northbound side of the highway.

On her Facebook page, Pickler said Lohman wasn’t just a drummer, “he is family.”

“I believe in the miracles and the power of prayer, so it would mean the world to me, my band and Gregg’s family if you would please keep him in your prayers,” Pickler wrote. “Thank y’all so much.”

Six people from rural Wisconsin were killed when the tractor-trailer rear-ended their Ford Expedition at about 11:13 a.m. EST Saturday in the northbound lanes near Glendale, Ky.

State Police said the family was returning to Wisconsin from a vacation to Orlando, Fla.

Chaffins said the tractor-trailer was following too closely to the SUV to stop before the collision. The Expedition was “totally engulfed in flames. It was totally destroyed by the fire,” he said, adding, “It’s just a charred mess.” Distracted driving is among the causes being investigated.

“That’s one of the points we’re looking into,” Chaffins said. “We haven’t pinpointed the exact cause.”

The two crashes shut down the busy stretch of highway for about five hours.
