Steve is nearly 7FT tall man of unknown Origin. His race is unknown because of the darkness surrounding his body. He's seemingly between 20-26 years old and is communicating through writing. He's escaping his cell but he's harmless just wandering around for food coming back by himself after eating.
He prefers eating dog food than any other human meals but despite that he enjoys normal deserts and responded accurately to the piece of chocolate cake in his room leaving only plate and spoon on the floor. Steve is showing signs of intelligence being able to solve mathematical problems since his only problem is lack of arms we allowed him to use tablets and touchscreen boards to write solve them. He didn't fail even at hardest one's.
Steve is not able to speak because of any parts of body that would allow him to.
If Steve gets closer to a person they can see only darkness before their eye's, for now we can't explain it.

His containers walls started dripping with this dark goo from the celling need to relocate object is considered and sent to the administration of the building.
