BTK Arrest: DNA Connection
March 4 - The DNA evidence gathered by police led to last week's arrest in the BTK case.
Now, KAKE News has learned more about the DNA evidence that helped lock Dennis Rader behind bars.
As we first told you Saturday, a package sent to KSAS-TV included a floppy disc that led investigators to the Christ Lutheran Church and prompted the FBI to get a DNA sample from Rader's daughter.
Sources say her DNA came back as a match on Thursday and investigators were considering making their move that night but instead kept Rader under surveillance. Friday, they arrested Rader not far from his home.
The police chief in Michigan where Rader's daughter lives tells KAKE News after Rader's arrest investigators interviewed his daughter Kerri.
Around that same time in Connecticut investigators reportedly arrived at the naval base where Dennis Rader's son Brian is in submarine school.
There is also new information on the search at Rader's Park City home.
Home video shows investigators taking several different items out of a shed. Fox News reports that investigators found jewelry in the shed. They say the jewelry is not related to any of the ten murders Rader has been charged with. Fox says its information comes from law enforcement sources.
KAKE News has also learned Judge Gregory Waller has sealed nearly all court documents pertaining to this case.
