High school years
Lincoln attended Graysford Academy, which is most likely a private school telling by its name. He was a graduate in the class of 1998. Which suggests he would have been a student at Graysford from 1994-1998. He apparently was doing well after high school according to his bio on Hornyhighschoolreunions.com. He states he moved in with his girlfriend, found a good job working as a mechanic and was setting up a plan for a family.
One night, sometime in 2005 Lincoln was under the influence of whiskey and PCP and decided to rob a liquor store. He claims it sounded like a good idea at the time. An officer that responded to the call was shot by Lincoln, dying instantly.
Lincoln is serving three years into a life sentence in the Alderney State Correctional Facility during the events of Grand Theft Auto IV. He happens to be the "prison bitch" of a biker going by the name of Digger Brass. If Lincoln graduated on time he must have been twenty five years old at the time of his arrest. Making him twenty eight years old by the events of GTA IV. He states he only wants cigarettes and a visit from his high school friends. Apparently, Digger tends to force Lincoln to shave his legs and also sleeps with Lincoln in his bed.
Strangely, Atwood doesn't have a file on the LCPD database.
