Dr. Kathleen Fabian Shot Dead by Boyfriend Thomas Williamson Amid Ignored Warning Signs, Port Huron Mourns

PORT HURON, Mich. — The Port Huron community is reeling after the shocking shooting death of Dr. Kathleen Fabian, a respected obstetrician, at the hands of her boyfriend, Thomas Williamson, 43. New reports reveal that repeated warnings about Williamson’s declining mental health and his access to firearms were reportedly ignored by local authorities in the weeks preceding the tragedy.

Friends and family members had raised concerns about Williamson’s unstable behavior and the dangers posed by his possession of guns—especially in a household caring for a severely autistic child. Despite multiple attempts to alert law enforcement and social services, no decisive intervention occurred.

“People tried to get help, but their calls went unanswered,” said a close friend of Williamson. “It’s devastating that these warnings were overlooked when action could have saved lives.”

A Devoted Doctor Taken Too Soon

Dr. Kathleen Fabian was a pillar of the Port Huron community. As a trusted obstetrician, she helped hundreds of women safely bring new life into the world, earning admiration for her compassionate care and unwavering dedication.

“She was a guiding light for so many families,” said one patient. “Her loss is unimaginable.”

Her death has left a deep void among colleagues, patients, and loved ones. Her children and family now face the heartbreaking reality of life without her.

The Incident and Investigation

Police responded promptly to reports from Dr. Fabian’s home, where she was found shot. Thomas Williamson was taken into custody and remains under investigation as authorities work to determine the full circumstances behind the shooting.

Officials have not yet released details regarding motives but confirm the incident is an active investigation.

Calls for Change on Mental Health and Gun Safety

The tragedy has sparked urgent conversations about how mental health crises and firearm access are handled locally and nationwide. Experts stress the importance of timely intervention and stronger policies to prevent individuals in crisis from having access to weapons.

“Had those warnings been acted upon, this might have been prevented,” said a local mental health advocate. “This is a painful reminder of the gaps in our systems.”

Community leaders and advocates are calling for reforms that include better mental health services, improved communication between agencies, and enhanced firearm safety measures.

Honoring a Life of Service

Memorial plans for Dr. Fabian are underway, with the community preparing to celebrate a life dedicated to healing and service. Her legacy will live on in the families she helped and the many lives she touched.

As the investigation continues, Port Huron stands united in grief and in the hope that lessons learned from this tragedy will bring about change to protect others in the future.
