LOUISVILLE, Ky. -

A Michigan trucking company involved in a crash that left six Wisconsin residents dead on Interstate 65 in central Kentucky over the weekend had a satisfactory rating from the federal agency that oversees long-haul carriers.

The Federal Motor Carrier Safety Administration based its ranking of Highway Star Inc., on a 24-month span in which the company fell below the national average of vehicle problems.

A tractor-trailer driven by 47-year-old Ibrahim Fetic of Troy, Mich., hit an SUV carrying a family back to Wisconsin from a vacation in Florida on Saturday. Fetic and two children in the SUV survived the crash.

Police said all occupants of the SUV were from Marion, Wis. They were identified as James Gollnow, 62, and his wife Barbara, 62; Marion Champnise, 92; Sarina Gollnow, 18; Soledad Smith, 8; and Gabriel Zumiga, 10.

Police said Soledad and Gabriel were foster children.

The two survivors were also foster children. Police identified them as 15-year-old Hope Hoth, who was transported to a hospital in Lexington with burns and a broken spine; and 12-year-old Aidian Ejnik who was taken to Kosair Children's Hospital in Louisville with cuts to the back of his head. Police described both of the children's injuries as non-life-threatening.

The wreck also set off a four-vehicle collision on the other side of the interstate. Police said 36-year-old Gregg Lohman, the drummer for country music singer Kellie Pickler, remained hospitalized Monday.
