First Ghost Hunting Adventure

In the Salt Lake Cemetary is the gravestone of a woman, Lilly E. Gray, with an inscription that reads "Victim of the Beast 666". Many people have tried to research this gravestone, along with Lillly, and have always come up empty handed.
Some say the phrase is based on religion. "The Beast" and "666" are both linked with Satan and Antichrist. There are speculations she was the victim of an exorcism gone wrong.
Also her name was Lily instead of Lilly, and her birth year was 1880 instead of 1881. Do these mistakes have an actual meaning, or was it just a mistake?

Last night was the first adventure of Team Phantom. We decided to search for this mysterious gravestone in the Salt Lake Cemetary, which is not the easiest thing to do seeing it was night, the cemetary is huge, and security is on the lookout.
Our first attempt at entering the graveyard was not a success. Security was slowly coming down the street, so we walked into a neighborhood. As we were crossing the street, a strange cloaked figure that was sitting on the fence of the cemetary started to follow us. We picked up our pace and rounded the corner and soon lost this mysterious person. We returned to our car and decided it would be best to park elsewhere.
Our second attempt was much more successfull. We entered the graveyard staying low to the ground and ran for the covers of the trees. Security came by so we laid on the ground until they passed, then dashed for the next set of trees, going further in. It was then that certain members of Team Phantom felt uncomfortable continuing this journey and had to turn around and return to the safety of the vehicle.
The remaining members of Team Phantom continued up the hill of gravestones trying to stay hidden from the site of anyone who may glance towards the cemetary. After awhile of climbing and dodging, the remaining members became weary and sat down to enjoy the view and take a load off their boots. The City of Salt Lake looked like burning lava from this resting place on the hill, yet you could see your breath in the crisp winter air.
After a few minutes of rest, we noticed we were sitting upon someones resting place. We vowed to take a picture of this humble gravestone on our return, and set off for Lilly's grave.
Several minutes later we came to a road in the graveyard, the address reading 1200 E 355 N. We were close. Inbetween the third and fourth tree we found the first gravestone of Lilly's row, Roy Mason Kidder. We counted nine gravestones and knelt down, we had found it. Lilly E. Gray, Victim of the Beast 666, lay in front of us. We took as many pictures as we dare to without anyone seeing the flash from our cameras from afar.

After our time spent with Lilly, we decided it would be best to return to our team down below. We came to the edge of the graveyard and decided to go over the fence to walk in the safety of the neighborhood back to the car.
It was then, after we jumped the fence, that we forgot to take the picture with Keck. We made our way back over the fence to find our resting place, and after finding it and taking our picture we made our way back.
