A preliminary hearing scheduled for Tuesday for a Michigan man charged with reckless homicide in a Sept. 14 ATV accident that killed a Quincy woman was postponed.

Andrew J. Koster, through his attorney, Barney Bier, filed for a motion of substitution of judge. Judge Chet Vahle recused himself from the case, which has been referred to Chief Judge Richard Greenlief for reassignment.

Vahle is the third judge to recuse himself from the case. Judge William Mays and Judge Scott Walden earlier had recused themselves.

Koster, 30, recently had his bond modified so that he could move back to Michigan. He was living in Clayton at the time of the accident.

Adams County Sheriff's deputies said he was the driver of a "mule" ATV that crashed in the early morning hours of Sept. 14 near Clayton on property owned by Golden Triangle Whitetails, a hunting outfitter that owns properties in Adams, Brown, Pike and Schuyler counties.

Sarah Birsic, 25, died as a result of injuries she sustained in the accident.

Koster was charged with felony aggravated driving under the influence the day of the crash. The reckless homicide charge was added a week later.

Koster posted 10 percent of a $10,000 bond on Sept. 14.
