Ryan Ricky Houston was a Weaverville, North Carolina, man who, while free on a $1.6 million bond and Buncombe County electronic monitoring for the attempted murder of a sheriff’s deputy, killed two people over two days in August 2024. He fatally stabbed his girlfriend, Malerie Crisp, then died alongside retired Marshall Police Chief Thomas Michael Boone in a wrong-way crash on Interstate 26. The case exposed hundreds of ignored monitoring alerts, a romantic relationship between Houston and the county employee assigned to supervise him, and prompted a state criminal investigation, felony charges against that employee, multiple wrongful death lawsuits, and a full overhaul of Buncombe County’s pretrial program.
Why He Was Out on Bond
Around 1:40 a.m. on May 7, 2023, Houston walked into the magistrate’s office at the Buncombe County Detention Facility in Asheville, where his wife, Laura Houston, was filing a domestic protective order against him. Earlier that night he had assaulted a male friend of his wife, fracturing the man’s face, damaging his home, and stealing a firearm.1WLOS.

How He Stayed Free Despite 244 Alerts
Between August 17, 2023, and August 2, 2024, Houston’s GPS device generated 244 alerts: 169 for a broken tether, 49 for signal losses, 20 for low or critically low battery, five for entering a restricted zone, and one for tampering after his SIM card was removed. None of them resulted in him being taken back into custody.6Asheville Watchdog. Weaverville Fugitive Had Romantic Relationship With Pretrial Caseworker
Rasnelly Vargas, the pretrial services coordinator assigned to supervise Houston, was in a romantic and sexual relationship with him during that period. Vargas admitted to the relationship in civil lawsuit depositions.7WLOS.

Houston did face at least one push to revoke bond. In early August 2023, prosecutors moved to revoke after a battery violation; Superior Court Judge Jacqueline Grant instead ordered house arrest with private monitoring, and days later signed an order returning him to jail until a county monitoring slot opened. He was placed back on county monitoring, and later violations in late 2023 and early 2024 were handled by other judges without pulling him back in.5Asheville Watchdog.

The August 2024 Killings
By mid-2024, Houston’s wife had filed for divorce and obtained an active protective order. On August 1, 2024, Houston failed to appear at a court hearing on that order.9ABC News 4. Could Ryan Houston Have Been Tried for Attempted Murder Months Ago That night he removed his ankle monitor.
Malerie Crisp, 41, was a single mother of two teenage boys who worked at the Waffle House in Weaverville. She had known Houston since high school and began dating him around 2022.6Asheville Watchdog.

Crisp was inside with stab wounds and was pronounced dead at a local hospital less than an hour later. Houston fled the scene.10Citizen-Times.

On August 2, 2024, Houston drove the wrong way on Interstate 26 near Mars Hill in Madison County and caused a head-on collision that killed Thomas Michael Boone, 54, who had retired as Marshall Police Chief just two days earlier. Houston also died in the crash.6Asheville Watchdog.

Criminal Charges and State Investigation
Because Houston died in the crash, no one could be prosecuted for the killings themselves. The criminal accountability that followed has focused on the pretrial program.
On April 6, 2026, a Buncombe County grand jury indicted Rasnelly Vargas on two counts of felony obstruction of justice tied to her official duties as Houston’s coordinator.12WLOS.

The Civil Lawsuits
Four civil actions have grown out of the case.
Deborah Cauble, Malerie Crisp’s mother and estate administrator, filed a federal wrongful death and civil rights suit on December 10, 2024, against Buncombe County, County Manager Avril Pinder, former Justice Services Director Tiffany Iheanacho, Pretrial Services Program Manager Cindy Green, Renee Ray, Rasnelly Vargas, and the collector of Houston’s estate. The complaint alleged gross negligence in failing to report more than 240 monitoring violations and sought damages exceeding $75,000.14Citizen-Times.

Former Deputy William Matthew Johnston, who was shot by Houston in 2023 and has since medically retired, sued for assault, battery, and gross negligence. A judge allowed him to amend the complaint to add Buncombe County and multiple county officials as defendants; the amended pleading alleges seven counts of negligence tied to Houston’s pretrial supervision.7WLOS.

What Buncombe County Changed
Under new Justice Services Director Regenia Herring, the county rewrote its pretrial rules. Defendants facing violent felony charges above a class H or I are no longer eligible for county pretrial services. As of May 21, 2025, the county stopped offering electronic monitoring altogether, returning existing cases to the courts, where judges can order state-run monitoring instead.16WLOS. Buncombe Co.
