Kelly grew up in a close-knit family with her elder brother Billy Jr. and her younger sister Lea. She was a bright and ambitious girl who excelled in her studies and participated in various extracurricular activities. She was also fond of nature and enjoyed spending time outdoors.

When Kelly was thirteen years old, her parents divorced, which was a difficult time for her and her siblings. She had to cope with the changes in her family and adjust to a new reality. She found solace in her friends and her faith. She also developed a strong sense of justice and a desire to help others.

Kelly attended Tidehaven High School, where she graduated as the valedictorian of her class. She then pursued higher education at the University of Texas in Austin, where she earned a Bachelor’s degree in International Business in 1984. She continued her studies at the South Texas College of Law, where she obtained her law degree in 1987.

Professional Career

Kelly’s passion for law and justice was evident from an early age. She was inspired by her father’s role in justice and by the stories of famous prosecutors and trials. She decided to become a prosecutor herself and joined the Harris County District Attorney’s Office right after law school. She quickly rose through the ranks and became a Bureau Chief of Special Crimes, overseeing divisions such as Major Offenders, Identity Theft, Major Fraud and Consumer Fraud.

Kelly‚Äôs career as a prosecutor was marked by her dedication, skill and success. She handled over 150 jury trials, including 68 murder cases and 20 death penalty cases.¬†She never lost a murder case and secured death sentences in 19 out of 20 cases. She was known for her aggressive and theatrical style in the courtroom, often using props, demonstrations and dramatic statements to persuade the jury.¬†She earned the nickname ‚ÄúThe Giant Killer‚ÄĚ for taking down notorious criminals and corrupt officials. Here is a brief timeline of Kelly Siegler‚Äôs professional career before her retirement:

  • 1984: Graduated from the University of Texas in Austin with a Bachelor‚Äôs degree in International Business.
  • 1987: Graduated from the South Texas College of Law with a law degree.
  • 1987-2008: Worked as a prosecutor at Harris County, Texas, where she was a bureau chief for Special Crimes Bureau and handled cases involving major offenders, identity theft, consumer fraud, and major fraud.
  • 2005: Made her TV debut on an episode of American Justice.
  • 2008: Retired from her prosecutor career and started working as a TV personality and consultant for various true crime shows.
  • 2013-present: Starred in the TV series Cold Justice, where she and her team reinvestigate cold cases and try to solve them.


After resigning from the Harris County District Attorney’s office in 2008, she embarked on a new mission: to help solve cold cases across the country. She joined the investigative series Cold Justice as an executive producer and on-camera investigator, bringing her expertise and passion to the small towns that often lack the resources and attention to crack their unsolved murders.

Since joining Cold Justice in 2013, Kelly has helped local law enforcement agencies make arrests and secure convictions in some of the most challenging and baffling cases. She has also brought closure and hopes to the families of the victims, who have waited for years or even decades for answers. Kelly and her team of rotating experts and investigators have tackled cases without DNA evidence, with aging witnesses, and with circumstantial evidence, relying on new interviews, forensic testing, and meticulous analysis to point to a suspect.

Kelly has also appeared on other shows related to her work on Cold Justice, such as the Martinis & Murder podcast, where she discussed some of the cases she solved and shared her insights on circumstantial evidence and jury presentation. She has also been on Forensic Files (2010), a documentary series where she appears as a prosecutor in one episode.


Former Harris County prosecutor Kelly Siegler is popular as a ‚Äúgiant killer‚ÄĚ for securing 19 death sentences in 20 capital cases. She later became the host of a crime-solving reality show called ‚ÄúCold Justice‚ÄĚ.

He was found guilty for a second time in 2019, but the jury could not decide on a sentence.¬†He was sentenced to life in prison in 2023 after a resentencing trial.
  • The case of Ronald Prible, a death row inmate convicted of killing a family of five in 2002. Siegler was found to have used jailhouse informants to fabricate confessions from Prible and to have given them undisclosed favors in exchange. She also violated Prible‚Äôs right to counsel by using informants as agents of the prosecution to interrogate him. His conviction and sentence were overturned in 2020 by a federal judge who called Siegler‚Äôs conduct ‚Äúegregious‚ÄĚ.
  • The case of Linda Carty, a British woman sentenced to death for kidnapping and killing a young mother in 2001. Siegler was accused of withholding evidence that Carty was framed by drug dealers who were her co-defendants. She also allegedly threatened and intimidated witnesses to testify against Carty.
