I've never seen the second print with a marker. Do you have link please?It's unknown male DNA found within the crime scene of the horrific murder of 4 people. How on earth could its fail that test? Further there are 2 footprints in evidence - a Vans footprint outside of DM's bedroom door and a footprint outside that CSI marked with evidence marker 3. Evidence marker 3 looks like a hiking boot or shoe footprint, not a Vans footprint.
