Attorney Clark was admitted to the
State Bar of California in 1979, where she continued to practice law. She worked in private practice and as a
public defender for the city of Los Angeles before she became a prosecutor in 1981. She worked as a deputy district attorney for
Los Angeles County, California and was mentored by prosecutor Harvey Giss. Clark is well known as the lead prosecutor in the
1995 trial of
O. J. Simpson for the murders of his ex-wife
Nicole Brown Simpson and her friend
Ron Goldman. Prior to the Simpson trial, Clark's highest-profile trial occurred in 1991 when she prosecuted
Robert John Bardo for the murder of television star
Rebecca Schaeffer. Clark said that the media attention that she received during the trial was "the hell of the trial," calling herself "famous in a way that was kind of terrifying." Clark was advised by a jury consultant to "talk softer, dress softer, wear pastels" in order to improve her image.
The New York Times commented that "the transformation was not entirely seamless."
Commentator and author Clark resigned from the district attorney's office after she lost the Simpson case. She and
Teresa Carpenter wrote a book about the Simpson case,
Without a Doubt, in a deal reported to be worth $4.2 million. Since the Simpson trial, Clark has made numerous appearances on television, including as a special correspondent for
Entertainment Tonight. She provided coverage of high-profile trials and reported from the
red carpet at awards shows such as the
Emmy Awards. She was a guest attorney on the short-lived television series
Power of Attorney and was also featured on
Headline News analyzing the
Casey Anthony trial. In July 2013, Clark provided commentary for
CNN during the Florida
trial of George Zimmerman. Clark wrote a
pilot script for a television series called
Borderland, centering on "a very dark version of the DA's office." The series was purchased by
FX but was never produced. Clark has written several novels.
Guilt By Degrees (2012),
Killer Ambition (2013) and
The Competition (2014).
Guilt by Association was adapted as a television pilot for
TNT in 2014. Clark's "Samantha Brinkman" series features a female defense attorney. It includes
Blood Defense (2016),
Moral Defense (2016) and
Snap Judgment (2017), and was planned as a television adaptation series for
NBC that Clark would cowrite. She read
Nancy Drew and
The Hardy Boys mystery fiction as a child and said "I have been addicted to crime since I was born. I was making up crime stories when I was a 4 or 5-year-old kid." ==Media appearances==
