Liz was unemployed on September 11, 2001 and pursuing a career in medical administration. On the evening of the 11th she began volunteering at Ground Zero. Her first week there she slept in doorways, afraid that if she left the site she wouldn't be allowed back in. Eventually she worked at the Hard Hat Café where she met John and Denise Casalinuovo.
Because of the admiration she held for the police officers at Ground Zero, she decided to pursue a career in law enforcement, eventually becoming a Private Investigator.
She also met Alex Lopez, a firefighter, whom she married in September, 2010. Tragically, Alex died of a heart attack on July 21, 2011.
