Early life and modeling

Neal was born in Alexandria, Virginia, and moved to Littleton, Colorado, when her father was promoted to the position of federal attorney in Denver². She is the youngest of three daughters². She was a competitive figure skater in high school, and began college at 16 after graduating high school early⁴^•³.

She was a pre-med major in university before leaving to pursue modeling². In 1993, during her first semester of college, her sister signed her up for a modeling contest and she landed a contract, then spent the next few years traveling the world for photo shoots³. She has described herself as having been a science kid who expected to go into medicine or astrophysics, and has said the travel during her modeling years fueled her interest in other people and circumstances³.

Law & Order: SVU

Neal's first screen role on the show came as a guest: in a 2001 episode of Law & Order: SVU she played a suspect, a woman involved in the gang rape of a man¹^•⁵. Having apparently impressed the producers with the guest spot, she joined the cast in 2003 as regular character Casey Novak, a by-the-book assistant district attorney⁵.

She featured regularly on the show until departing in 2008, then returned as Novak in 2011¹. IMDb credits her with appearances on the series from 2001 to 2021 totaling 114 episodes². On breaks during filming she quizzed the show's guest stars about what motivated them, saying she wanted to absorb what she could from everyone she met on a job³. She later said that in preparing the role she researched real SVU cases in New York, calling them heartbreaking⁶.

Other television and film work

Crime dramas. In 2010 Neal took on the recurring role of Coast Guard Investigative Service Special Agent Abigail Borin on NCIS, playing to her crime-drama strengths¹. IMDb lists her as Borin on NCIS from 2010 to 2014 across 6 episodes, and on NCIS: New Orleans in 2015 across 3 episodes². Her 2011 return to SVU meant she juggled her two best-known characters for a time; her second stint on SVU did not last long, and she focused on NCIS and a recurring spot as attorney Allison Holt on the legal drama Suits, 3 episodes between 2012 and 2014⁵^•². Other guest work listed by IMDb includes The Following (Lisa Campbell, 4 episodes in 2015), Blue Bloods (Kelly Blake, 1 episode in 2015), and Power (Cynthia Sheridan, 4 episodes in 2014)².

Film. While in the midst of her initial SVU stint she appeared in the straight-to-video horror sequels Dracula II: Ascension (2003) and Dracula III: Legacy (2005) as Elizabeth Blaine⁵^•¹. Rotten Tomatoes lists her highest-rated film appearance as Newlyweeds (2013) at 71% and her lowest as Dracula II: Ascension at 0%¹. Later credits include the 2021 television movie Circle of Deception, in which she played Peggy Sue Thomas², and the 2013 Hallmark Channel movie This Magic Moment, in which she played Helena Harris²^•⁷. On stage, BroadwayWorld credits her with Love, Loss, and What I Wore and The 24 Hour Plays 2007⁸.

Education and politics

Neal enrolled at the Harvard Extension School in 2009, working online from New York, on the road between shoots, and on campus when she could³. She chose it over programs at Columbia and New York University because a flexible schedule suited filming in distant locations, and she valued the academic variety; courses she cited included the psychology of close relationships, the ethics of environmental land management, and the science of physical activity³. She graduated with an associate degree in May 2018³.

In February 2018 she announced her candidacy for New York's 19th Congressional District seat, running as an Independent. "This run is about the people of NY19," she said. "Big money and the party machines have enough advocates"³. She has said her desire to enter politics crystallized on November 9, 2016, with the country's polarization fueling her wish to get involved³.

A professional profile lists her as owner of Prodigal Daughter, Inc., a role she has held since January 2003, and records her congressional candidacy under House District New York 19 from December 2016 to November 2018⁹.

Personal life

IMDb's biography records her marriage to Marcus Fitzgerald on July 9, 2005, ending in divorce in 2014, and lists her parents as Chris Neal and Colleen Neal⁴. Her height is listed as 5 feet 10 inches (1.78 m)⁴. In interviews she has described running plot lines by her father, a real-life federal attorney¹⁰.
