Lori lived and grew up in King County, Georgia. In high school, Lori met Rick Grimes, a fellow student. She also became friends with Rick's best friend, Shane Walsh. Eventually, Lori and Rick fell in love with each other and became married. Together, they had a son named Carl. They lived as a typical suburban family in King County, Georgia. On Sundays, she made pancakes, despite the fact that she knew they were awful.

Over time, their marriage became increasingly strained with Rick distancing himself from her. His unwillingness to talk about his feelings and their problems resulted in fights, where harsh words were spoken by Lori. It had even reached the point where she began to question his love for her and Carl. Days before the apocalypse, Lori confided in a friend, Paula, to ease the stress and seek advice. Shortly after, Lori was told through Shane about Rick being shot and shared the news with Carl.

Lori, along with Carl, Shane, and a bed-ridden Rick, still resided in King County when the outbreak occurred. Lori tried for days to call her mother to see if she was okay but she never picked up - Lori assumed she had died in the outbreak. Two weeks into the outbreak, it got too dangerous to stay in King County and the military directed them to Atlanta where a safe-zone was established. Before leaving, Shane tried to gather Rick from the hospital, but returned to Lori and Carl claiming that Rick had died.

On the road to Atlanta, Lori along with Carl and Shane were caught in a traffic gridlock. There, they met Carol Peletier, her husband Ed, and their daughter, Sophia. Lori and Shane became concerned when the radio for the safe-zone stopped playing and believed that they were turning people away - until they discovered that Atlanta had become overrun with the dead and was napalmed by the military for Operation Cobalt.

Along the side of the road was a quarry lake outside of Atlanta. Lori along with Carl, Shane, Carol, Ed, and Sophia established the survivor camp. They were later joined by people who couldn't make it into the city: brothers Daryl Dixon and Merle Dixon, Glenn Rhee, Theodore Douglas, Morales and his family. Other survivors later joined them who managed to escape from Atlanta: Dale Horvath, sisters Andrea and Amy, Jim, and Jacqui.
