You may not recognize Bill Kurtis name or face, but if you watch true crime shows, you definitely know his iconic voice. The veteran Chicago TV journalist has been the host, narrator and producer for some of the most popular and longest-running true crime docuseries: A&Es Investigative Reports, American Justice and Cold Case Files, which was nominated for two primetime Emmy Awards in 2004 and 2005.

Cold Case Files has been revived both on A&E and Netflix, and now Kurtis is back again, this time on Hulu, with Cold Case Files: DNA Speaks. Each episode of the 10-part docuseries features a decadesold case that was solved using DNA evidence some of it collected long before investigators had the technology to analyze it and identify a suspect.

Kurtis, whom you might also recognize as the narrator of the Anchorman films and the announcer for NPRs Wait Wait Dont Tell Me!, told HuffPost last week about some of the most memorable crimes hes covered some that still keep him awake at night and whether he thinks a life sentence is harsh enough punishment for some killers.

He noted that most cold cases that are solved share a common denominator: loved ones never-ending pursuit of justice for the victims, and investigators dedication to finding closure for those families.

In these cases, theres always someone waiting for it to be solved, Kurtis told HuffPost. I call these the grandmother solutions family members who regularly check in with police, contact news outlets and hold public memorials to make sure the murder victims arent forgotten.
