The Perfect Couple: Michael and Kathleen's Love Story

In the mid-1980s, neighbors Michael Peterson and Kathleen Atwater found love when neither was looking for it. Both were recovering from recent separations with children to consider, but their connection proved irresistible. They merged their families in 1987, creating what appeared to be an ideal American blended family. By the 1990s, their professional success allowed them to purchase a stunning 14-room home in Durham's wealthiest area, and they finally married in 1997 after Kathleen's divorce was finalized.

  • Michael Peterson moved to Durham, North Carolina in 1986 after his marriage fell apart, bringing his two adopted daughters while his sons stayed in Germany with their mother
  • Kathleen Atwater was the first woman admitted to Duke University's Engineering Program and worked as an executive for Nortel, earning an impressive salary
  • The couple's daughters became best friends, with Caitlin enthusiastically viewing the family merger as a 'permanent sleepover'
  • In 1992, they purchased a beautiful 14-room home in one of Durham's nicest areas, funded by their combined professional success
  • Michael published 'A Time of War' in 1990, which became a New York Times bestseller based on his Vietnam War experiences
" She was immensely funny, intelligent, warm, and just so quick. "
" How would you like it if Martha and Margaret come live with you? And I immediately thought, a permanent sleepover? "

Mounting Pressures and the Fatal Night

By 2001, stress was mounting in the Peterson household. After the 9/11 attacks, Kathleen's company Nortel faced financial crisis, putting her job in jeopardy and causing her stock options to plummet by over a million dollars. Michael's political ambitions also crumbled when his mayoral campaign failed after he was exposed for lying about receiving Purple Hearts in Vietnam. On December 8th, 2001, the couple decided to take a day for themselves with Christmas shopping and wine by the pool, but the evening would end in tragedy.

  • Nortel Networks suffered major financial losses after 9/11, with Kathleen's retirement account dropping by over a million dollars and forcing her to fire employees
  • During Michael's mayoral campaign, reporters discovered he had lied about being injured by shrapnel and receiving two Purple Hearts; he actually was injured in a car accident in Japan
  • Michael sold film rights to one of his books for $600,000, providing some financial relief during this stressful period
  • On December 8th, 2001, Michael suggested they spend the day Christmas shopping and relaxing by the pool with wine to decompress
  • Around 1 a.m., Kathleen went inside to prepare for an important conference call the next morning while Michael stayed by the pool
" Confronted with his military record, Peterson disclosed that the leg injury actually occurred in a car accident in Japan. He said not even his family or closest friends knew the truth. "
