Law officers arrested Blurton at his home in Garnett, Kan., early Saturday. He’s charged for the shooting deaths of Donnie and Sharon Luetjen and their 15-year-old granddaughter, Taron. Law officers found their bodies in their home on June 9 but they might have been killed two nights previously.

After Blurton was charged, a judge sealed the probable cause statement because detectives are searching for at least one other person for the murders. Detectives said releasing the PC statement might jeopardize that search. On Tuesday, the judge allowed part of that statement to be released but many parts of it are blacked out to protect witnesses and to keep some of the evidence secret to prevent tipping off another suspect about what detectives know.

In the PC statement, Benton County Sheriff Rick Fajen says the 911 call from the Luetjens’ home came about 10:16 p.m. on Sunday, June 7. After the called ended suddenly, a call-taker returned the call but got the Voice Mail message box for that number.

Missouri doesn't have a system to allow 911 centers to pinpoint the location of a cell phone that calls 911. Some lawmakers and law enforcement officials have tried for many years to get voters to authorize a cell phone tax to pay for such a system but the efforts have failed.

After the murders in Cole Camp, investigators examined the recording of the call. Fajen says at least two men can be heard in the background of the call.

“One of the male voices was directing Sharon Luetjen to sit down, put her arms behind her and at least two threats to shoot her and the other two victims. . . . The male(s) could be heard shouting commands and threats at the three victims,” Fajen wrote.

Someone familiar with the Luetjen family listened to the recording at Fajen’s request. Fajen says that person recognized the men’s voices. That person told detectives that one voice on the recording was Robert Blurton, also known as Robbie.

Robert Blurton told detectives, Fajen wrote, that he lived with the Luetjens for a while before he went to prison. He also told detectives that he hadn’t seen the Luetjens or been in their home since Christmas 2003. Fajen believes that’s a lie because an analyst matched Blurton’s DNA with DNA found at the murder scene.

The probable cause statement indicates Blurton’s brother, Marvin, told detectives that the motive for the robbery and murder of the Luetjens might have been that Robert Blurton owed money to people whom he met in prison.

"Marvin told investigators that his brother Robbie may have owed money to inmates he associated with while in prison and in June he was called by one of those inmates in an attempt to locate Robbie. Marvin also told investigators that his brother Robbie has some ‘pretty shady friends that would be worth checking out’,” Fajen wrote.

The PC statement indicates several weapons and some money was taken from the Luetjens' home and Sharon Luetjen's purse.

"There was no evidence anything was ransacked and minimal objects were out of their normal storage places," Fajen wrote.

Fajen says Blurton, 45, has been convicted for 12 felonies, including first-degree robbery and burglary.

Online court records show, in 1996, Blurton pleaded guilty in a circuit court in Jefferson City for possession of a controlled substance at a correctional facility, and received a three-year prison sentence that was served concurrently with one he was already serving. The records don't show what that previous sentence was for.

Blurton pleaded guilty for two counts of forgery in Benton County in January 2005, for crimes committed in 2004, and received a four-year prison sentence. A spokeswoman for the Missouri Department of Corrections says prison records show he was released from prison in January 2008 but failed to report to a community correctional center and was returned to a state prison on Feb. 19, 2008. He was released from prison at the completion of his sentence on Nov. 24, 2008.

Online records also indicate Blurton was sentenced in Kansas on July 19, 2005, for a theft that occured in November 2004. He served his Kansas sentence at the same time as his Missouri prison sentence. Kansas released him from its supervision on March 22, 2007, while he was still in a Missouri prison.

Blurton is now in the Allen County jail in Iola, Kan. He has refused to waive his right to be extradited to Missouri. Extradition is a legal procedure in which one governor formally asks another governor to return a prisoner to the first governor’s state to face charges. Arrested people often waive that procedure, allowing law officers to bypass the governors’ offices and the second state’s court system and speedily return a prisoner across state lines.

Even though Blurton is in the Allen County jail, the extradition case will be handled in Anderson County court in Garnett, Kan., where Blurton lives. Anderson County doesn't have a jail right now. Blurton's next court appearance is scheduled for Aug. 13.
