Otsego County Fugitive Arrested After Two-Day Search Following Crash
William Killenberger was taken into custody after authorities spent two days searching for the East Worcester man following a serious Westford crash.
An Otsego County fugitive was arrested after two days on the run, ending a search that began after authorities said 39-year-old William W. Killenberger fled from a serious motor vehicle crash in the Town of Westford. CNYHomepage reported Friday that Killenberger had been arrested after the two-day search. The arrest ends the immediate public safety concern that prompted deputies to warn residents not to approach him.
Killenberger, of East Worcester, had been wanted on an active warrant for first-degree assault, according to the Otsego County Sheriff’s Office. Authorities previously said additional charges were pending.
The arrest brings one chapter of the case to a close, but significant questions remain about what happened before and during the Aug. 4 crash and what charges Killenberger will ultimately face.
Otsego County Fugitive Search Began After Westford Crash
The case began Tuesday, Aug. 4, when authorities said Killenberger was involved in a serious motor vehicle crash in the Town of Westford.
According to the Otsego County Sheriff’s Office, Killenberger fled the crash scene on foot.
By Thursday, Aug. 6, deputies were publicly asking for help finding him and believed he remained somewhere in the Westford area. The sheriff’s office identified him as William W. Killenberger, 39, of East Worcester.
Authorities issued an unusually direct warning to residents.
“Do not approach or attempt to apprehend. Killenberger may be armed,” Sgt. Richard Kimmerer of the Otsego County Sheriff’s Office said in the public notice.
CNYHomepage subsequently reported that Killenberger was arrested after spending two days on the run.
The accessible sources reviewed for this report did not provide enough independently verifiable information about exactly where or how he was captured. Those details are therefore not included here.
What Killenberger Was Wanted For
Deputies said Killenberger had an active arrest warrant for assault in the first degree.
Under New York law, first-degree assault is a serious felony charge involving allegations of serious physical injury under circumstances defined by state law.
An arrest warrant and criminal charge are allegations. They do not establish guilt. Killenberger is presumed innocent unless proven guilty in court.
Authorities also said several additional charges were pending.
As of the reports reviewed for this article, officials had not publicly provided a complete explanation of how the first-degree assault allegation was connected to the Westford crash.
That distinction matters.
Without additional information from investigators, prosecutors or court records, it would be inappropriate to speculate about:
- Who was injured in the crash
- How severe those injuries were
- Whether another vehicle was involved
- What allegedly happened before the collision
- Whether the vehicle itself was allegedly used to cause an injury
- What additional criminal charges may be filed
Those questions could become clearer as the case moves into court.
Two-Day Search Put Westford Residents on Alert
The search placed residents of the rural Otsego County community on alert for roughly two days.
Law enforcement believed Killenberger remained in the Westford area after leaving the crash scene on foot. Deputies asked anyone who had seen him or knew his whereabouts to contact the sheriff’s office rather than attempting to apprehend him personally.
The warning was particularly important because authorities said he might be armed.
Westford is a largely rural community, and searches in such areas can present challenges that are different from searches in cities. Woods, fields, barns, seasonal properties and long distances between homes can make it more difficult for officers to locate someone traveling on foot.
The reported arrest means residents no longer face the same immediate warning associated with the active fugitive search.
Previous Law Enforcement Encounters
Public records and local reporting also show that Killenberger had previous encounters with the Otsego County Sheriff’s Office.
In December 2024, the sheriff’s office arrested Killenberger following an investigation into a domestic dispute in East Worcester. WCDO reported that he was accused of damaging property and leaving before law enforcement arrived.
Deputies later located him. Authorities alleged he fought with deputies while they attempted to take him into custody.
Charges reported in that separate case included criminal mischief, aggravated harassment, endangering the welfare of a child and resisting arrest.
Earlier that month, Killenberger was also arrested on multiple weapons charges after investigators executed a search warrant at an East Worcester residence.
WCDO reported that investigators recovered multiple firearms and ammunition. The sheriff’s office was assisted by New York State Police.
Those earlier cases are separate from the August 2026 investigation. Prior arrests do not establish guilt in the current case.
What Happens After an Arrest?
Once a fugitive is taken into custody, the focus generally shifts from locating the suspect to the court process.
That can include:
- Processing by law enforcement
Officers formally record the arrest and applicable charges. - Arraignment
A judge advises the defendant of the charges and considers release or detention under New York law. - Prosecution review
Prosecutors evaluate police reports, witness statements, physical evidence and other information before determining which charges will move forward. - Future court appearances
The case can proceed through hearings, motions, plea negotiations or trial.
Additional details about Killenberger’s case may emerge through those proceedings.
Arrest Ends Search, But Investigation Is Not Over
Killenberger’s reported arrest resolves the most immediate question facing authorities and residents: where he was.
It does not resolve the larger investigation.
Officials have yet to publicly provide a full account explaining the serious Aug. 4 crash, the circumstances surrounding the first-degree assault allegation or the additional charges deputies said were pending.
Those facts will ultimately be more important than speculation surrounding the two-day search.
For residents, the case also offers a reminder about the role the public can play during an active law enforcement search. When authorities warn that a wanted person may be dangerous, residents should report credible information and allow trained officers to handle an apprehension.
Now that Killenberger has reportedly been arrested, attention will turn to the Otsego County court system and whatever evidence investigators present.
The Utica Phoenix will update this story as verified information about the arrest, charges and court proceedings becomes available.
