For the record, you lazy fucks don't deserve this.
Special Containment Procedures: Item SPC-173 is to be kept in a locked container at all times. When personnel must enter SCP-173's container, no fewer than 3 may enter at any time and the door is to be relocked behind them. At all times, two persons must be looking at SCP-173 until all personnel have vacated and relocked the container.
Description: Moved to Site19 1993, little is known about item number SCP-173's origins. It is constructed from concrete and rebar and was once painted with Crylon brand spraypaint.
SCP-173 is animate and malevolent, if given the chance it will kill anyone within its line of site. Its weakness however is that it does not move while being watched. Despite this paralysis it is still highly dangerous, able to cover at least 2 meters in the literal blink of an eye. It typically kills by either snapping the victim's neck from behind, or grabbing the victim's throat and strangling them. Whatever animates SCP-173 does not give it much force with which to break things; as seen above, a large room with unbarred windows is fully capable of containing it. Its grip however is unbreakable, as when it is not moving the statue is as hard and strong as concrete.
While left alone in its room, one can hear a stone-on-stone scraping from within that is believed to be the sound of the SCP-173 moving about.
The reddish brown substance on the floor is a combination of feces and blood. We don't know (nor wish to find out) where it comes from or how it arrives but SCP-173's container will slowly fill with these substances. In order to ensure that bacterial growth within does not begin to damage the building it is contained in, and to maintain some level of sanitation, the enclosure must be cleaned on a bi-weekly basis.
