Black Cedar Beetle?

Black Cedar Beetle?
Seattle, King County, Washington, USA
February 7, 2018
Size: 3/4"
Black. Very passive. Does not run in reaction to light or touch. Found an adolescent in 2nd story hallway last week. Found this adult stuck upside-down just inside the front door on the floor today. These were my first sightings. I did not hear any noise coming from them.

No idea what this is but my best guesses are ranked below.

Carabus nemoralis, methinks
Definitely not Sandalus. Also quick note - don't trust insectidentification.org. Several of their photos are misidentified

Spot on!
After googling for "carabus nemoralis", that certainly seems a match! Even down to the 2 spots of slight coloration where the thorax joins the abdomen! Thank you!

Good to know about that site. It seems that Carabus nemoralis are relatively well-regarded (good for gardens). Should I be worried if I find an abundance indoors?

No, don't worry
Metrioptera beat me to it while I was typing.

Just throw the insect outside, it will do no harm indoors.

nah
They're probably just accidentally wandering indoors looking for food (or maybe for warmth since its winter).
