Jessie Slater (formerly Jessie Wolfhart) is the wife of Dannie Slater. She has a very timid yet kind attitude which she uses to her advantage in order to make a lot of connections and gain information. She works as a manager for RedLine under Archie Cooper.
Back in Silver Lake, Jessie was always emotionally unstable. She had to provide for herself due to the fact it was only her and her alcoholic, gambling addicted father, August Castle, who wasn't around all that often. She had her family friend Adam Stone who helped her out in the police force but she was very back and forth mental health wise. She worked as an officer who patrolled the streets for awhile then switched into the Marshal Service where she collected taxes from people who refused to pay for long periods of time. She used her job and finding information to distract herself and keep from going to dark places. On top of losing her husband of a few months after he decided to up and vanish without a word, she began to dwindle down a dark path. When Jessie had a little incident with her dad bringing up that he found someone who might've been her mother (but wasn't), she snapped and tried to kill herself off of a bridge outside of town. Marco Holliday prevented her from jumping and saved her. She gave it a few weeks to recover then moved to Los Santos without telling her father or anyone anything other than Marco Holliday where she was going.
She moved to Los Santos with the intention of finding a new job, keeping to herself and trusting no one. She was very straight forward, independent and had a low tolerance to many things. Dannie Slater was the light at the end of Jessie's tunnel. He was so full of life and kind and caring and compassionate and truly cared for her even though they didn't know each other for that long. Jessie fell for Dannie almost instantly but was too stubborn and hard headed to even admit that.
Jessie's strong suit has always been the game of information. With her personality being very friendly, calm and open with people, she began to make many connections throughout Los Santos and used it to her advantage. She kept a notebook with information she has obtained and uses it to get herself and Dannie out of dangerous situations. She kept this notebook and added to it on multiple occasions. The first job Jessie got in the city was being an informant for Jimmy Hillside where she obtained information on other gangs which she would give to The Grove Street Collective. This was the start of improving her skills in order to gain information on everyone in the city that could possibly protect herself and Dannie when they get into trouble.
With the amount of people Dannie would constantly upset or make angry, Jessie always stood behind him and tried to rebuild the bridges that had been burned for one reason or another. The two often had a few arguments and have broken up three times but in the end, they stood by each other's side when things got rough. Dannie and Jessie would only taunt and mess with people who messed with them first. The revenge they sought was often stealing their most personal possession, often their cars, and launching them off of the Del Perro Pier. Launching stolen cars into the water became one of their signature moves and there are many cars at the bottom of the pier including one of Avery Jenkins' Taco Vans, Lang Buddha's signature pink van, Abdul al-Rahim's taxi and more.
Timmy Macapone arrived in Los Santos looking to start a crew to get his loan business rolling. He wanted a small group but he wanted them to be proficient. He ended up picking up Bruce Greenwell as his right hand and his driver, Dannie Slater as his fall guy who did all of the dirty work and street work and Jessie Slater who was his hidden wildcard who gained all kinds of information on whoever he requested. Jessie was basically a walking encyclopedia for Macapone and no one knew she was even affiliated with him. The four worked well but it came slowly to a stop when Macapone began to have a thing for Katie Rage and apparently so did Bruce, which caused.. issues within the business.
While the love triangle between Macapone, Katie and Bruce was going around, Dannie managed to piss off a man who should have never been messed with by the name of Richard Oakes. Richard Oakes is a world famous Serial Killer who died at the hands of Tony Andrews, a police officer for the San Andreas State Police. Richard Oakes knew of Jessie's strong connection to Dannie and when Richard could not get to Dannie directly, he went after Jessie. The two went on a nature hike after Jessie and Dannie had gotten into an argument which led to Richard questioning Jessie about her life, family, goals, aspirations, etc. He struck her with his hatchet multiple times and left her to bleed out at the end of Raton View middle trail that faces towards Cassidy Creek. This left Jessie with life threatening injuries and in the hospital for quite awhile but she pulled through.
On June 21st, 2018, Jessie and Dannie decided to make it official and got married at the courthouse. Leon Church, Penny Wise and Grant Mchenry were present for the ceremony. Later that night, Dannie Slater was kidnapped by Edward Jasper and Darren Fole and was later killed in the swamps by the Military Base. His body has not been found. Jessie was in the dark and went on a man hunt to figure out who did this to Dannie and where he was for two months. Leon Church suggested that Jessie should make a list of everyone in her phone book and cross off people who aren't suspicious. If they were suspicious, they should be given a number 1 to 10, 1 being least likely and 10 being most likely to know something. She made two copies of the list, one is hidden in the box on the end of the pier where the life ring is and Tidus Martel is aware of this location. The second list has been sent to Gunnar Mason, a close friend of Jessie's.
