Wichita ? The Kansas Supreme Court has turned down an appeal from a seizure-prone driver who killed two teen-agers when his pickup slammed into the back of their car.

Michael Jenkins, 49, had been free on bond. He faces a 31-month prison sentence imposed in October 2000.

Jenkins had suffered from seizures since he was a child. Evidence at his trial showed that he had been involved in seven accidents in the nine years before his collision with Kim Yauk and her two children on Aug. 19, 1999.

Jenkins said he didn’t remember what happened in the moments before his pickup rammed Yauk’s car as it sat at an intersection in Wichita. Brett Kunkel, 13, and his sister Laura, 15, died from their injuries.

On Friday, the Supreme Court rejected each of Jenkins’ appeals.

“It’s been 2 1/2 years,” said Dick Yauk, Kim’s father and the grandfather of the victims. “I was scared if the appeal was upheld we were going to have to go through it all again.”

A jury convicted Jenkins in August 2000 of involuntary manslaughter and of lying to the Department of Revenue about his previous accidents to keep his driver’s license.

Jenkins could still file a request for the court to reconsider its decision. Those aren’t often filed and are rarely granted.

Jenkins could be on his way to prison by May, when trial is set in a civil suit.
