Duke "Diezel" Winchester, 25 years of age, was born and raised in a trailer park in the eastern side of Sandy Shores. He was raised by his 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 him 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 awhile then. Diezel wasn't always the brightest kid. He once drove a dirt bike straight off a cliff for a Twinkie. Didn't break 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 a 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 a 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 him 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 a 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 hes talking, his head will twitch to the side. He doesn't know it himself but everyone sees it and don'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 5 mph, the average person runs probably at 15 mph. His morning routine consists of 5 cigarettes, a cup of coffee and 2 Monster Energy Drinks and he's ready for his day at about 11 am 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 of 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 bandanna to cover his balding head which he is a bit self-conscious about.
