Tammy Mal Biography

Tammy Mal is a Pennsylvania-based true crime author recognized for her contributions to historical crime and investigative nonfiction. Mal has written for True Detective Magazine and Absolute Crime Publishing, focusing on older, lesser-known cases that are both unusual and historically significant. A former member of the Pennsylvania State Police Department, she has conducted extensive research into criminal cases, drawing on her background in law enforcement and investigative writing.

At age 47, Mal self-published her first book, "Little Girl Lost: The True Story of the Vandling Murder," which examines the murder of 9-year-old Mae Barrett. She followed with "Tortured Minds: Pennsylvania's Most Bizarre—But Forgotten—Murders," a collection of obscure murder cases from the 1930s, and "Murder in Susquehanna County," which explores cases such as the Margaret and Mary O'Mara murders. Mal's work is noted for its thorough research and clear presentation, appealing to readers interested in criminal justice, forensic investigation, and Pennsylvania history.

Mal authored "Convenient Suspect: A Double Murder, a Flawed Investigation, and the Railroading of an Innocent Woman," published by Chicago Review Press. The book investigates the murder of Joann Katrinak and her infant son in Catasauqua, Pennsylvania, and examines the conviction of Patricia Rorrer, presenting evidence and analysis from more than 10,000 official documents, including Pennsylvania State Police reports, FBI files, forensic lab results, and trial transcripts. Mal is the only journalist to have interviewed Patricia Rorrer, providing unique insight into the case through years of research and direct communication.

Mal and her work have been featured on the crime documentary Murder in Lehigh Valley: Keith Morrison Investigates, producer Joe Berlinger's series Wrong Man, and Investigation Discovery's Reasonable Doubt. She has also appeared on the podcast "You Be the Judge" and has spoken at libraries, historical societies, and book clubs. With a catalog of more than seven true crime books, including "Disposable Income: A True Story of Sex, Greed, and Im-purr-fect Murder" and "Shared Circumstances: The McCabe-Riley Case," Mal explores forgotten crimes and examines issues of justice, investigative integrity, and historical narrative in the true crime genre.
