Lise Olsen is a Houston-based investigations editor at the Texas Observer. Lise has investigated many twisted Texas tales, including crooked judges, an unjust execution, massive environmental disasters, myriad cases of corporate and public corruption, and unsolved serial killings. Her reports in three states over 20 years contributed to the prosecutions of a former congressman and a federal judge, inspired laws and reforms, helped solve cold cases, restored names to unidentified murder victims, and freed dozens of wrongfully held prisoners. She is the author of The Scientist and the Serial Killer.
