Axel Jakobsen was born to Erik and Carina Jakobsen of Norway. Erik was the Norwegian Ambassador to the UK and the little family just continued to grow after Axel. In total there were six Jakoben children. Axel, the oldest. Astrid, five years younger than Axel. Johanna, six years younger than Axel. Kjerstin, seven years younger than Axel. Regina, eight years younger than Axel and finally Magnus who was ten years younger than Axel. The large family seemed perfect... however the Jakobsen's had a dirty secret.
Erik Jakobsen was an alcoholic and when he got into his drunken rages nothing good came out of it. He became physically abusive towards his kids when Astrid was born. Apparently two kids was his breaking point. It started out with just some slaps across the face but it eventually escalated into punching. The littlest thing could set Erik off into using any of his children or his wife as a punching bag. However there wasn't any knives used... that is until Axel was 13. Erik drew a knife on Axel and gave him a scar across his cheek. Axel went to the hospital of course... and Axel claimed that he had cut himself accidentally.
The abuse continued throughout Axel's childhood up until he was 17 when he moved out of the house. With only one year left Axel dropped out of school to pursue a career in professional quidditch. Quidditch had been Axel's safe have from his father and he was good at it. Plus there was good money in it. Axel used that money to buy a large house for him and his family in Norway. They moved out of the house and Carina got a divorce from Erik citing 'irreconcilable differences'. Carina won custody however Erik was given visitation days for his kids under 17, which at the time was all of them except Axel and Ida. The abuse continued on those visitation days however until it all came to a tragic ending.
It was a cold winter's day in January, 2027. Magnus, the youngest Jakobsen child was visiting his father. Erik was drinking. Again, then he started to beat on Magnus. However this time, Erik didn't stop. He continued to beat Magnus until he was dead. Erik then took the body and dumped it in the river. Erik told Carina and her family that Magnus ran away. However because Magnus was under Erik's charge and all the other suspicious things that happened to the Jakobsen kids, he was stripped of his visitation rights.
Magnus' body was found two year later by a pair of fishermen. After a through investigation by the Norwegian Aurors, the murder was traced back to Erik. Erik Jakobsen was then brought to trial and found guilty of murder and sentenced to life in prison. However the fact that Erik abused all his kids was never revealed. No one except the Jakobsen family and Axel's teammates know that, and Axel intends to keep it that way. It's better to just leave Erik rotting in a jail cell then to bring his family through another trial.
