Blood Oath Murder
"Why would he walk from the bedroom to the kitchen to get a knife unless he was planning to kill her?" Matheson asked rhetorically at trial. "There is no reasonable explanation other than that was the plan."
There was little argument from the defense that Christensen had not killed Sherry. However, Christensen's attorney, Kathleen Kyle, said that he killed Sherry in a rage, and that there had been no forethought prior to the killing.
"It was not calculated or precise," Kyle averred.
Kyle also maintained that Christensen's actions after the murder were not planned, but were instead a "sadly pragmatic way for a desperate man to cover up a terrible crime."
Jurors were shown a store surveillance video that depicted Christensen driving Sherry's car and purchasing cleaning items.
On Friday, June 4, 2010, the jury agreed with the prosecution's case and swiftly convicted Christensen of first-degree murder after deliberating about three hours. After the verdict was read, Christensen laughed loudly as he was led out of the courtroom in shackles, and continued laughing, cackling as some witnesses described it, as his guards returned him to jail to await sentencing.
On Friday, June 18, 2010, Christensen was sentenced to 37 ½ years in prison, the judge telling Christensen that he had committed "a barbaric act."
