Jolene was born in 1956, before the date of March 24th. At some point before 1978, she met and married stuntman John "Jock" Cranley.
In 1978, Jolene and her John, had been experiencing troubles in their marriage. Jock wanted to leave Blaine County to pursue his dreams of becoming a stuntman, but Jolene wanted to stay, saying that she had to look after her parents and run their thriving guest house. Therefore, whilst out walking by the cliffs overlooking the El Gordo Lighthouse, Jock pushed Jolene over the edge of the cliffs and she fell to her death. The police arrested Jock on suspicion of murder, but he was released without charge after the police investigation concluded that Jolene's death was accidental.
Her spirit appears at the top of Mount Gordo at night, between 23:00 and 00:00. When the player approaches it, it disappears (although can always been seen through a sniper rifle scope). She has a permanent petrified open-mouthed look on her face, as well as leaves rotating around her. The only movement the spirit makes is a very slight bobbing in a circular motion. Moans can occasionally be heard from her. On the rock that the ghost floats over, the name "Jock" is written with blood, accusing her husband of murder. This serves as an Easter Egg.
Also, near some tents on the trail leading up to the ghost's spirit, and exclusively on next generation consoles and PCs, faint screams and whispers can be heard after 10 pm in-game time. There are two separate falling screams and two different inaudible whispers. The ghost noises can only be heard at the camp site of the mountain, this could likely be because that was the side of the mountain where she fell to her death.
The ghost doesn't have an actual in-game model, and is just a 2D texture coded to appear and disappear. In the enhanced version, the player can get very close to the ghost without it disappearing by switching to First-Person mode and aiming down the sights of a weapon. The disappeared ghost will instantly re-appear if the player continues aiming. If the player approaches the ghost from the west, they can get as close as they want without the ghost disappearing.
Extreme caution is advised when travelling to the location and viewing the ghost as Mount Gordo is a popular location for cougars that can kill the player-character instantly. It's advised to use Trevor (whose special ability allows him to survive attacks) and be armed at all times.
The ghost can easily be viewed from within Director Mode by setting the time to Midnight and then adjusting back; toggle "freeze time" to spend as much time as desired examining the ghost and the message.
