Terrie Biggs book ties La Grande launch to unsolved Sylvia case

Terrie Biggs will return to the place where local memory still has sharp edges, signing her 10th book at Cook Memorial Library on Saturday, April 25, at 2 p.m. The event at 2006 Fourth St. in La Grande centers on Sylvia, A Life Stolen & Others Missing and Mourned, a project rooted in the unsolved murder of Sylvia Heitstuman, a La Grande mother of six whose case has stayed with Biggs since she moved to town in April 1982.

Biggs’ connection to the case began almost immediately after she arrived in La Grande. Three months later, while visiting a friend, her husband said hello to Heitstuman. After Heitstuman was killed, Biggs kept thinking about the loss and later, while working at the police department, learned more about the investigation. That experience became the starting point for years of research and a book that Cook Memorial Library describes as a tribute to Heitstuman’s life and family.

The new book reaches beyond one case. Biggs says half of it is devoted to Sylvia’s story, while the rest examines 20 other local cases from 1978 to 2024 across three rural counties. Only a few of those cases have been solved. To assemble the book, Biggs used newspaper archives, more than 40 interviews and local records, building a record meant to keep victims and their stories from disappearing into silence.

The book is already available in paperback on Amazon and at Community Merchants in La Grande, with Kindle and Audible versions as well. Biggs also used AI narration tools for the audiobook, which uses five AI narration voices. She listened closely, taking notes on pauses and the pronunciation of local place names, a detail that reflects how deeply rooted the project is in Eastern Oregon geography and memory.

The release lands in a region where cold cases still shape public concern. Oregon State Police says its Cold Case Unit investigates unsolved homicides, missing persons and unidentified human remains cases, using solvability criteria such as actionable leads, forensic evidence, surviving witnesses and historical documentation. In August 2022, Oregon State Police and Union County Search and Rescue carried out a forensic search on about 3 acres tied to the long-unsolved Finley Creek Jane Doe case. They found more than 50 bones, but the state medical examiner later confirmed none were human.

Finley Creek Jane Doe was found on Aug. 27, 1978, near Elgin on Finley Creek Road, about 10 miles northwest of town, and remains unidentified. Biggs’ book places Sylvia Heitstuman’s killing alongside cases like that one, giving La Grande readers a work that is part history, part testimony and part record of how a community carries its unresolved grief.

Biggs’ first published work came out in 2012, after 20 years of research on a Whitman Mission book, and she has written several books tied to Union County. That makes the Cook Memorial Library signing more than an author appearance. It is a reminder that in La Grande, the stories people still remember are often the ones that have never been fully answered.
