OMAHA, Neb. (AP) — A detective says an argument on Facebook between two men may have led to a fatal shooting in northwest Omaha.

Detective Michael Smith testified during a preliminary hearing Tuesday that an argument between 31-year-old Kenneth Armour and 30-year-old Michael Stubbs began with a comment to a Facebook post and escalated via phone.

Armour is accused of fatally shooting Stubbs on Nov. 5. Smith testified that Stubbs identified Armour as the shooter before he died.

Armour faces several felony charges in the case, including first-degree murder. A message left for his attorney was not immediately returned Tuesday.
