I disagree.
Bittrolff's brother was convicted of a misdemeanor... that's how his DNA was in the system. Testing revealed that DNA was genetically related to DNA/semen from McNamee & Tangredi.
From news report:
The trail that police said led to Bittrolff began with a DNA sample submitted by his brother Timothy Bittrolff following his misdemeanor conviction for violating an order of protection in 2013.
After the analysis of the sample indicated it was a partial match to DNA left on the two dead women, investigators looked at Timothy Bittrolff's brothers.
First, they retrieved a cigarette butt that one brother, Kevin Bittrolff, had tossed from his car. But his DNA wasn't a match.
Investigators then set up a camera outside John Bittrolff's home. When he left nine bags of trash outside, they swooped in.
A carpenter was convicted on Wednesday of murdering two prostitutes found beaten to death in the 1990s and faces 50 years to life in prison.
