COOPER TOWNSHIP, Mich. (AP) – The condition of one of four bicyclists injured in a crash that killed five others has improved.

Bronson Methodist Hospital in Kalamazoo reports that Sheila Jeske has been upgraded to fair condition from serious. Paul Runnels remains in serious condition at that hospital.

Paul Gobble is in serious condition and Jennifer Johnson is in fair condition at Borgess Medical Center in Kalamazoo.

They were injured Tuesday evening on a country road north of Kalamazoo in Cooper Township where they were struck from behind by a pickup truck that reportedly had been driving erratically. The driver was a 50-year-old man who fled but was caught by police shortly afterward. He remained in custody Thursday.

County prosecutor Jeffrey S. Getting said he expected a report Thursday from the sheriff’s department and other agencies that would help determine whether charges would be filed.
