Duct work, pipes, and metal filling the courtroom during the trial of the Lima anesthesiologist accused of killing his first wife through carbon monoxide poisoning.
Kathy Wangler died in 2006. Dr. Wangler had the duct work cleaned about two months later. Sheriff's deputies removed vents, pipes, and carpet samples in late 2007. Finding an agency to analyze the samples for traces of exhaust proved to be difficult.
The state believes the carbon monoxide which killed Kathy Wangler came from combustion engine exhaust.
The Ohio State Highway Patrol, the Environmental Protection Agency, and the FBI were all contacted to complete testing to prove this theory. None had the equipment or expertise. Finally, the Wisconsin State Lab of Hygiene was called and agreed to the testing.
Experts explained that testing for trace particles was completed. Further explanation of the findings should be revealed in the next few days.
Also, the list of state witnesses continues to grow. Judge Richard Warren ruled Dr. David Davis can be called to the witness stand. Davis is a former coworker of Wangler. Davis read an article about the case just before the trial began and remembered a conversation he had with Dr. Wangler weeks before Kathy's death. Wangler apparently told Davis, Kathy wanted a divorce, but that Wangler said divorce was not an option. Defense lawyers objected to the testimony, saying the addition would be unfair this late in the proceedings. However, Judge Warren disagreed.
Dr. Davis is expected to testify on Thursday.
