Jacob was born in Missouri to two parents who were originally from the UK, he was raised in a Christian household, growing up Jacob was bullied a lot, through school and generally around his hometown in Jackson. His first encounter with the Sheriff's Department was when he was walking home at the age of 12, two kids stopped him on the sidewalk and started asking for his money. He threw a punch at one of them and that's when a Deputy lit up the sidewalk from his crown victoria, the Deputy saw what had happened and sent the bully on his way, giving him a stern warning to not go around bullying people again, Jacob felt that he was in debt to the Sheriffs Office for helping him out, and from that day he decided he wanted to become a Deputy Sheriff.
At the age of 19, he joined the academy and went through his training, he then branched off to become K-9 unit handler, where he took in a little pup, it was a Belgian Malinois dog, he decided to name it Blitz, due to it being very fast. He raised the dog and trained it specifically for police work, such as searching for drugs, weapons, biting suspects etc. He and Blitz entered active service in the Sheriffs Office at the age of 21. His daily life consisted of traffic stops, assisting other deputies in foot chases with Blitz and more. In February of 2014, Jacob's father passed away in a hit and run by a suspect in a car, he bailed on foot and fled the scene. Jacob blames himself for not being able to stop it.
In mid-2017, Jacob and Blitz, along with Jacob's partner Deputy Blaire requested work leave to have a break from the Sheriffs Office, Jacob was an avid explorer, Alex Blaire was also an avid mountain climber. So they flew over to Chernarus with Blitz to explore the mountainous and towns of Chernarus. They went all over the place until reports of the infected started to come in, they tried to move over to the airport to escape, they managed to get a lift from a civilian in a car, Blitz jumped onto Jacob's lap with Alex beside him. As they drove but the car that they had got a lift from started taking shots from a military checkpoint close to the airfield. Blitz took three bullets to the body which essentially saved Jacob, however, Jacob was shot in the abdomen and was knocked out from shock, Alex died of blood loss. Jacob was presumed dead by the military and was left in his car. When Jacob woke up in a makeshift hospital zone near Stary, he already knew that Blitz was dead and that a new life was about to start.
Jacob doesn't know that Alex is dead however, he still thinks that Alex survived and is surviving along with him, this is all simply an illusion inside Jacob's head, you will often see Jacob talking to thin air, conversating with the soul that is no longer there. Although Jacob isn't mentally insane, and acts normal, revealing Alex's body to Jacob may cause a major breakdown.
