Prosser murder suspect McCorkindale back in court

Tri-City HeraldJuly 31, 2013 

— The trial date has been moved to October for a 24-year-old man accused of stabbing a Prosser man, then running him over twice to make sure he was dead.

Robert B. McCorkindale signed a waiver Wednesday that delays his trial almost two months to Oct. 14.

He’s charged in Benton County Superior Court with first-degree murder.

McCorkindale allegedly told investigators that on June 14 he drove “to a remote location for a drug deal with (Preston) Yahne.”

The two men got into an argument while waiting on another person to arrive.

McCorkindale claimed that Yahne pulled out a box cutter and tried to stab him with it, but McCorkindale was able to disarm him before grabbing his own knife from a leg strap and hitting Yahne in the chest, court documents said.

Yahne, 22, tried to run away but McCorkindale got into Yahne’s car and drove after him, turning the car around several times because he kept missing the fleeing man, documents said.

McCorkindale then checked to make sure Yahne was dead, put his body in the trunk and the following day drove Yahne’s Dodge Avenger to a gravel pit in Sunnyside and set it on fire to dispose of evidence, prosecutors allege.

Yahne’s burned body was found inside the trunk days later by a tow truck driver. His family reported Yahne missing on June 16.

McCorkindale is charged in Benton County because investigators suspect Yahne was killed within the county boundaries before his body and car were driven to South Emerald Road, south of Sunnyside.

McCorkindale is in jail with bail set at $250,000.

Judge Sal Mendoza Jr. has been assigned to preside over McCorkindale’s case. He told the attorneys Wednesday that he wants them to work on an order outlining key dates and motion deadlines so they have a smooth pretrial process.
