From your description, it sounds like an inadvertent liquid spill on the keyboard. 

I am not judging and I could be wrong. People frequently spill stuff on their laptops.

Any liquid containing sugar,  tea coffee or a soft drink will have that effect on a laptop keyboard.

The way to resolve the issue is to replace the keyboard with a new one
