A Texas man has been taken into custody following the tragic death of his wife, which occurred last week under circumstances that remain under investigation. Authorities are treating the incident as an “unexplained death,” while they gather more information.

The victim, 33-year-old Chelsea Spillers, was a beloved high school biology teacher in Alvarado, Texas. Her life was cut short on Saturday, October 18, when her body was discovered in the home she shared with her husband. According to the Alvarado Police Department, this discovery came after a welfare check was requested at her residence.

FOX 4 news reported that law enforcement officials were called to Chelsea’s home, where they found her deceased. The initial findings point to blunt force trauma as the cause of her untimely death, as noted by preliminary evidence and a coroner’s assessment. These details have led investigators to suspect Chelsea’s husband, Brandon Ashley, to be involved in this tragic incident.

Chelsea Spillers was a high school science teacher cherished by her students and colleagues alike. Her untimely passing has left the community in shock, as they await further developments in this deeply unsettling case.

Investigators now suspect that her husband, Brandon Ashley, was responsible for her death, which was caused by blunt force trauma, according to preliminary evidence and a coroner’s report, the outlet reported. 

On Monday, authorities received reports of a shirtless man trespassing at a residence in Bedias – located about 150 miles south of Alvarado – the previous day, the Grimes County Sheriff’s Office said in a statement. 

The individual, who was later identified as Ashley, was reportedly believed to be experiencing a mental health episode while walking on private property Sunday morning, according to police. He was also spotted knocking on neighbors’ doors to ask for a shirt, while allegedly making comments about avoiding a nearby highway because there were “too many cops,” the department said.

Ashley was taken into custody Monday morning after he told officers he had stashed a pistol near a local convenience store around where he was arrested, according to police. Authorities later recovered an Astra .357-caliber pistol near the store.

Following his arrest, deputies learned that Ashley was wanted for Spillers’ alleged murder in Johnson County. 

“The police department would like to remind the public that an arrest is not a conviction, and the suspect is presumed innocent until proven guilty in a court of law,” Alvarado police said in an update, according to FOX 4. “The investigation remains ongoing as the case is prepared for presentation to the District Attorney’s office.”
