“concoct a ‘witness’ or two who “saw” his white Hyundai at the scene.”
Actually they had the white Hyundai on a nearby convenience store security cam footage in the time frame of the murders and started sifting through the registration data bases immediately. The suspect had a WSU parking pass, so his name was known to police earlier than we realize. Then they got the warrant for his cell phone and watched him while waiting for the forensic DNA processing to be completed.
Once the had that hard evidence match, they arrested him. And the Moscow police kept their mouths shut, unlike the gossipy Pennsylvania cop.
“And the Moscow police kept their mouths shut, unlike the gossipy Pennsylvania cop.”
Yep. Keep the mouth shut during an active investigation. Release only carefully parsed info to keep the perp feeling confident. Let the Press concoct any stupid articles they like and chuckle at their stupid conjectures.
