Matthew Ambuhl, 59, was a resident of Lampasas, Texas. He lived with his wife, Suzanne, in a home on Antelope Lane.
The discovery of his death began with a technological alert on the afternoon of Tuesday, October 20, 2026. At approximately 3:58 p.m., a medical monitoring company received a notification from a pacemaker worn by Matthew, indicating a possible health emergency. The company contacted authorities, dispatching emergency medical personnel to the 700 block of Antelope Lane.
Investigators would later learn that the pacemaker data was not transmitted in real-time but uploaded at intervals, causing a significant delay. The data showed the actual emergency had occurred on the evening of the previous day, Monday, October 19.
When first responders arrived at the residence, they found Matthew Ambuhl deceased on the back porch. He had sustained traumatic injuries from gunshot wounds. Officers from the Lampasas Police Department entered the home to investigate further. Inside, they discovered Matthew’s wife, 59-year-old Suzanne Ambuhl, dead on the living room floor. A firearm was found in close proximity to her body. Officers also found two deceased cats inside the home, both of which appeared to have been shot.
The Lampasas Police Department, with assistance from the Texas Department of Public Safety's Texas Ranger Division, launched an investigation into the deaths. The case was described as an isolated family-violence incident with no ongoing threat to the public. Both Matthew and Suzanne were transported to the Southwestern Institute of Forensic Sciences in Dallas for autopsies. While final reports were pending, preliminary findings indicated that Matthew Ambuhl's death was a homicide and Suzanne Ambuhl's death was a suicide. These initial conclusions were consistent with evidence collected by investigators at the scene.
During the investigation, police became aware of a social media post made to Suzanne Ambuhl's Facebook account on October 19, the day of the shootings. In the post, she claimed that her husband was threatening to kill her. However, based on evidence gathered, investigators believe the post was created and published after Suzanne had already shot and killed Matthew.
The police department released information to the public to address rumors and misinformation circulating within the community. They confirmed that they had not received any calls or reports about the social media post on October 19, nor had they been alerted to any disturbance at the Ambuhl residence prior to the discovery. A review of department records also showed no history of reported family violence incidents at the home.
The incident was the first fatal shooting to occur within the Lampasas city limits since July 2024. As of late October 2026, the investigation remained active, though authorities believed all individuals involved were deceased at the scene. The case was ruled a murder-suicide, with Suzanne Ambuhl identified as the perpetrator.
