LOUISVILLE, Ky. – 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.”

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

Killed were 62-year-old driver James Gollnow and his wife, 62-year-old Barbara Gollnow; 92-year-old friend Marion Champnise; 18-year-old Sarina Gollnow, relationship unknown; and foster children 10-year-old Gabriel Zumig and 8-year-old Soledad Smith.

Two other foster children survived and were taken to area hospitals. Police identified them as Hope Hoth, 15, who was transported to a hospital in Lexington with burns and a broken spine; and Aidian Ejnik, 12, who was taken to Kosair Children’s Hospital in Louisville with cuts to the back of his head.

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.”

Chaffins said despite snow flurries, weather was not a factor in Saturday’s crashes. The driver was identified as 47-year-old Ibrahim Fetic of Troy, Mich. Police were looking at his driving logs and collected a blood sample.
