LA CROSSE, Wisconsin (WXOW) -- A local lawyer says while the evidence against Eric Koula seems compelling and convincing, people should remember the presumption of innocence until proven guilty.
Lawyer Peder Arneson says as a son of the murdered couple, forensic evidence against Eric Koula will be hard to put forward.
It is expected that Eric's fingerprints, hair and other DNA would be around the house.
Using forensic evidence alone could make it hard for the prosecution to prove Eric's guilt.
Arneson also says to remember, these are his parents.
"It would be a significant act to be able to kill your parents. You can kind of see it in a one parent or one family member in a fit of rage, but to be able to patiently do two of them, not many people that could do that," he says.
As Arneson says, investigators may have much more against Koula, but the forensics angle alone may be tough to pursue.
