Luke grew up in Scotland with his mother. Even though his mother brought him up on her own they done fairly well and had a decent life, but that came at a price. His mother was constantly working trying to make ends meet which meant that Luke was left at home on his own. He didn't have many friends and always looked out for himself than others. It was just after his 16th birthday he truly ended up alone. Him and his mother were in a car accident, some motherfucker thought it was acceptable to do a Hit 'n Run and leave his mother to bleed out on the road. He made sure to get a look at the mans face and the details of the car. A week or so had past when he tracked the man down. Broke into his house at night but the alarms went off. The man attacked him with a knife, cut his arm. He grabbed an ash tray and hit the man in the head. He grabbed the knife and placed it into the mans chest. He took the mans car to the airport and took the first and only flight leaving the country.
He landed in Chernarus with nothing to his name and within a week the dead began to walk. Ever since then Luke's been looking out for himself only doing things that can benefit him.
