A defense expert witness in a Leavenworth County murder case testified Thursday about his work in the case.

The testimony came during a hearing in the case of Dan S. Flannagan.

Flannagan, 65, is charged with intentional second-degree murder in connection to the death of Constance Perryman.

Perryman’s body was found April 6, 2018, on property located off of 198th Street south of Linwood.

Flannagan and Perryman had been living together on the property.

The case is scheduled to go to trial May 4 in Leavenworth County District Court.

Dr. Lyle Noordhoek testified Thursday about his work in the case.

Noordhoek was hired through the State Board of Indigents’ Defense Services to review the report of the autopsy of Perryman and other information related to the case on behalf of the defense.

Thursday’s hearing came after Deputy County Attorney Joan Lowdon expressed concern about things mentioned in a report generated by Noordhoek that she felt may have been beyond his expertise.

Noordhoek, who works in the area of forensic pathology, said he initially reviewed information related to the autopsy and then requested additional information related to the case.

He said the additional information allowed him to compare the autopsy report with what was found at the scene. After reviewing the additional information, there was nothing he could add to his initial findings.

Noordhoek testified that Perryman died as a result of a shotgun wound. The doctor said he had excluded suicide and listed the manner of death as being a homicide, accident or undetermined.

Noordhoek said he included “undetermined” because he was unable to determine if the death was the result of a homicide or accident.

“It’s a catchall,” he said.

Following Noordhoek’s testimony, Lowdon said she previously had concerns because a supplemental report from the doctor had mentioned things such as tire marks and gunshot powder. The prosecutor said she had concern about how these things came into play regarding his findings.

Lowdown said she would not object if Noordhoek testifies during the trial as he did during Thursday’s hearing.

Lowdon said she may file a motion to limit testimony about some of the information in the doctor’s supplemental report.

Flannagan remains in custody at the Leavenworth County Jail.
