If I remove one from eleven it becomes Ten and if I remove one from nine also becomes Ten. How?

A man is lying dead in a field where no one is around. His head is split open and his legs are disfigured. Near to him, there is an unopened package. No living organism can be found anywhere at the crime scene.

Present in sun, but not in rain,
Doing no harm, and feeling no pain.
