After a standoff with police last spring where he allegedly thrust a sword through his bedroom door and sparked an 11-hour standoff that resulted in his mother's Riverton home being ripped open, 63-year-old Ron Allington has reached a plea agreement with prosecutors. The agreement says Allington could face up to 5 years in prison plus fines and restitution, but he can argue for a lesser sentence.

Why it matters

This case highlights the challenges law enforcement faces when responding to barricaded suspects with mental health issues, as well as the collateral damage that can occur to innocent bystanders' property during these types of high-stakes standoffs in residential neighborhoods.

The details

During the April 2025 standoff, officers and deputies from numerous agencies surrounded Allington's home with rifles and shields. An armored vehicle remained in front of the house for several hours as the Riverton Volunteer Fire Department and emergency medical personnel stood by. Around 4 a.m., police deployed tear gas and arrested Allington, who was reportedly armed with a knife and a BB gun. No one was shot, but the back of the home was ripped open in an attempt to extricate Allington.

  • On April 16, 2025, the 11-hour standoff took place at Allington's mother's home in Riverton.
  • On April 18, 2025, Allington was charged with 3 felonies and 2 misdemeanors related to the standoff.
  • In July 2025, a judge ordered a second mental health evaluation for Allington to determine if he could be made well enough to participate in his cases.
  • On January 28, 2026, the evaluator found Allington competent to stand trial.
  • On April 1, 2026, Allington reached a plea agreement with prosecutors.
