19-Year-Old Charged with Felony Arson After Idaho Police Say He Set Rexburg Home on Fire
Rexburg Man Faces Multiple Felony Charges Following Wednesday Afternoon Blaze
REXBURG, Idaho — A 19-year-old Rexburg man was arrested Wednesday after police say he intentionally set fire to a trailer home on Airport Road, injuring no one but prompting a rescue by first responders and resulting in significant smoke damage to the structure.
Sebastian Louw has been charged with two felonies: first-degree arson and battery against a health care worker, according to the Rexburg Police Department and the Madison County Sheriff’s Office. If convicted on both counts, Louw could face up to 28 years in prison.
According to a Facebook post from the Rexburg Police Department, first responders were dispatched to the trailer home after receiving a report of a structure fire with people still inside. Officers arriving on scene forced entry through a window to remove Louw from the burning trailer.
Authorities say the incident began around 1:22 p.m., when Louw allegedly told a woman inside the home — identified as his registered healthcare worker — that “bad s*** was about to happen.” Louw then reportedly placed a notebook, a blanket, a DVD player, Tupperware, and two fire alarms on a gas stove and turned on the burner.
When the woman attempted to turn the stove off, Louw allegedly threw a large glass bowl and a trash can at her. She was able to escape the trailer, but police say Louw locked himself inside. First responders rescued him from the burning structure.
Firefighters quickly extinguished the flames, though smoke damage spread throughout the trailer. Police confirmed that Louw and the woman were the only individuals present at the time of the fire.
Competency Evaluation Requested; Bond Reduced After Indigency Finding
Louw later told police that he had started the fire as part of a plan to commit suicide, according to authorities. His public defender, Jim Archibald, filed a request for a competency evaluation, which had not yet been completed as of this report.
Louw was booked into the Madison County Jail on an initial bond of $25,000. The court subsequently reduced that bond to $10,000 after finding Louw indigent. He is scheduled to appear in court for a preliminary hearing.
As with all criminal cases, Louw is presumed innocent unless and until proven guilty in a court of law.
The battery charge against a healthcare worker underscores an ongoing concern in Idaho and across the nation regarding violence directed at individuals providing in-home care services — workers who are often in vulnerable, one-on-one settings with little physical protection. East Idaho communities have increasingly focused on the safety of those providing direct care in residential environments.
The arson charge carries serious weight under Idaho law, particularly given that the fire was set in an occupied structure. First-degree arson, when a building is inhabited at the time of the offense, represents one of the more serious fire-related charges available to Idaho prosecutors.
The case also highlights broader mental health challenges facing young adults in eastern Idaho. Community resources remain available for those experiencing a mental health crisis. Local support programs, including family-focused outreach efforts recognized at the national level, continue to work to connect at-risk individuals with services before crises escalate. In Idaho, anyone struggling with thoughts of suicide can call or text the 988 Suicide & Crisis Lifeline at 988.

Bonneville County News will continue to monitor this case as it moves through the Madison County court system.
What Comes Next
Sebastian Louw is scheduled to appear in court for a preliminary hearing. A competency evaluation requested by his public defender is still pending and may affect how the case proceeds. Prosecutors will determine whether the evidence supports moving forward to trial on the felony arson and battery charges. Bonneville County News will provide updates as new information becomes available through the courts.
