WICHITA, Kan. (AP) — A Kansas judge has rejected a request to video record DNA testing of biological evidence in a capital murder case, but said he might allow a defense expert to monitor the tests.

The Wichita Eagle reports District Judge Jeff Goering said Friday he would make a final ruling in two weeks. He gave prosecutors until then to gather evidence to show why a defense expert should not be allowed into the lab.

The testing is related to the November shooting deaths of Melissa and Roger Bluml of Valley Center. Prosecutors say swabs from some items would be tested for DNA, but the swabs would be consumed in the process.

The Blumls’ adopted son, his biological mother and two of his former high school classmates are charged in the case.
