John Gill Commentary Mark 15:45

"And when he learned it of the centurion, he granted the corpse to Joseph." — Mark 15:45 (ASV)

And when he knew it of the centurion
Who might inform him of his giving up the ghost after he had cried with a loud voice, which so much affected him; and how he was found to be really dead when they came to break the legs of the malefactors; and how that one of the soldiers pierced his side with a spear, from which flowed blood and water; so that there was no room to doubt of his being really dead; with which Pilate being satisfied,

he gave the body to Joseph ;
ordered it to be given to him; gave him leave to take it down from the cross, and inter it.
