The driver fled the scene, but later returned and was taken into custody.

Colleen McKinney, 44, was pronounced dead at 9:55 p.m. after Logan County Paramedics rushed her to the Abraham Lincoln Memorial Hospital emergency room, Logan County Coroner Bob Thomas said today.

Her husband and driver of the motorcycle, Thomas "Scott" McKinney, 49, was taken by ambulance to Memorial Medical Center in Springfield where he was undergoing surgery this morning, a hospital spokeswoman said.

Thomas McKinney suffered injuries to a hip, according to Thomas. Lincoln police detective Sgt. Tom Rowland said initial reports suggested McKinney may have been experiencing some paralysis.

Because surgery was in progress this morning, hospital officials were unsure of his current condition or his prognosis, the spokeswoman said.

Police said the McKinneys were not wearing helmets at the time of the crash.

Rowland said they were westbound on a 2005 Harley Davidson Electra Glide Classic when a 2001 Ford Escape driven by 21-year-old Lincoln resident Matthew L. Armstrong struck them.

Armstrong, of the 500 block of Third Street, allegedly fled the scene but was arrested on charges of reckless homicide, leaving the scene of an accident and drunken driving when he returned to the scene about 9:45 p.m., Rowland said.

Lincoln police, who were assisted by Illinois State Police accident reconstructionist Dan DeRenzy, closed off a two-block section of Keokuk between College Avenue and Kankakee Street for several hours until investigators finished collecting details necessary to reconstruct the accident.

DeRenzy said initial evidence suggests the point of impact between the motorcycle and the sport utility vehicle occurred in the outside westbound lane of Keokuk and the northbound lane of Ottawa.

Rowland said police detained Armstrong at the scene after he returned to the site with an unidentified female passenger. Armstrong was taken to Abraham Lincoln Memorial Hospital were physicians administered a blood test that indicated Armstrong's blood alcohol content was over the legal limit, he said.

In a fatal accident, Rowland said, investigators have the authority to require blood tests of drivers.

Thomas said forensic pathologist Dr. Jessica Bowman of Springfield performed an autopsy at Memorial Medical at 8 a.m. today, but preliminary results were not available and Thomas would not speculate about the possible cause of death.

He said a coroner's inquest will be scheduled in about six weeks after the necessary police and medical reports are completed.

Armstrong, who faces felony charges of reckless driving and leaving the scene of an accident, is being held in lieu of bond.
