SENECA ROCKS, W.Va. (WBOY) — Another man is dead and West Virginia State Police are investigating after a deadly “road rage type incident” in Tucker County that happened on Labor Day and led to a standoff, state police confirmed Wednesday.

On Tuesday, State Police said they were looking for a green, 2005-2011 Toyota Tacoma that was missing its passenger side window in connection to the road rage incident that resulted in the shooting death of a Dry Fork man identified as Joseph Nelson, 46. Life-saving measures were attempted, but according to a state police press release, Nelson was pronounced dead on the scene.

Now, state police say the suspect in the incident is dead as well.

State police said that on Tuesday they obtained a warrant for Daniel Sanders, 41, of Fellowsville for second degree murder, but when he was located at a home on Mountaineer Drive in Seneca Rocks, “a standoff ensued” between him and law enforcement officers with the West Virginia State Police Franklin Detachment, SRT and local task force, as well as a negotiator.

West Virginia State Police Capt. Robert Maddy said in a second press release that before entry could be made, law enforcement heard gunshots coming from inside the residence, and upon entry, Sanders was found dead “as a result of what is believed to be a self-inflicted gunshot wound.”

A follow-up investigation is underway according to the Tucker County detatchment.
