Duke "Diezel" Winchester, 25 years of age, was born and raised in a trailer park in east side sandy shores by meth-head mom, Linda. Linda died in a meth-lab explosion when Diezel was 24. His dad who he never knew the name of abandoned him as a child. Tami Jo, his twin sister, and he did everything together ever since they were born. She went and married some honky named Bobby after she got out of juvie back in the day and they stopped hanging out for a while then. Diezel wasn't always the brightest kid. He once drove a dirtbike straight off a cliff for a twinkie. Never broke a single bone that day but it gained him some huge reputation for doing some crazy stuff. It left him with a huge adrenaline junkie rush and he started doing crazy stunts all over Los Santos in stolen vehicles. Diezel got his nickname doing stunts in an 'ol Peterbilt big rig that he rebuilt himself. It took him 4 years to get all the parts for it so he started working for Sandy's Gas Station around the age of 20 years old to get some money and ended up quitting his stunt for awhile. His truck was black and green and rolled coal like an oil vape contest. It left him broke as hell again though until his mom died in that huge meth lab explosion.

Diezel found out later that he and Tami Jo inherited a huge sum of money from their mom when she died. Diezel asked Tami Jo if she wanted to start a garbage disposal company together. He is high strung gung ho kind of guy and driving is his thing so doing any kind of driving job fits the bill. Some of his stunts left him with a bit of a tick in his head so occasionally while he's talking his head will twitch to the side. He doesn't know it himself but everyone sees it and doesn't pay much attention to it. His body build is large and in charge, he weighs about 313lbs at 6'2". Diezel smokes like a chimney and has the absolute worst athleticism. His max running speed is about 5mph, the average person runs probably 15mph. His morning routine consists of 5 cigarettes, a cup of coffee and 2 Monster Energy Drinks and his ready for his day at about 11am on average. His dress attire is usually any kind of rock band name and blue denim jeans. Diezel has a full sleeve tattoo of large breasted women, beer kegs, Peterbilt truck(his of course) and Marlboro Reds. On his other arm, he has his mom's name Tattoo'd on the backside of his arm and on the front side is an ar15 and the NRA logo inside of an American Flag. There is also a bald eagle tattoo on his lower back which he got while intoxicated at a bar one night. He always wears an American flag bandana to cover his balding head which he is a bit self-conscious about.
