AUGUSTA, Maine (WABI) - Testimony continued Tuesday in the Scott Bubar trial in Augusta.
Multiple DNA experts testified.
Bubar's charged with aggravated attempted murder of an officer during a police-involved shooting in Belgrade last year.
Bubar's father, Roger, was killed during the stand off.
One of the state's forensics experts testified that Roger Bubar's DNA was found on a shotgun.
She also said there was a mixture of other DNA on the shotgun that she could not identify.
The defense's expert says she used the state lab's data and was able to rule out Scott Bubar from the mixture of DNA.
The trial continues Wednesday.
