The two of them climbed up a tree, where DM was groomed by her love. Things suddenly - and tragically - took a turn for the worse when DM fell out of the tree and hit the ground. She was alive, just barely - and her husband, as well as other female monkeys, rushed to her side to groom her for nearly an hour.
Sadly, she eventually passed away.
However, her male partner remained with her body even after the other monkeys left it. He continued to touch her for minutes after, before leaving to join the rest of his group. He kept looking back in her direction until the group left the area later in the day.
Researchers buried DM's body, but the next day, her husband found the spot where she rested, to quietly observe her grave before leaving once again.
