Three Muslim students were killed in Chapel Hill, N.C., at a condominium complex near the University of North Carolina by Craig Stephen Hicks who turned himself in to authorities.

Continuing reporting on the matter indicates that speculation is swirling that the killings were motivated by Muslim hate, however, preliminary investigations by authorities have suggested a more common cause.

“Our preliminary investigation indicates that the crime was motivated by an ongoing neighbor dispute over parking,” said the Chapel Hill Police Department. “Hicks is cooperating with investigators and more information may be released at a later time.”

Observers doubt the official narrative, however.

The Council on American Islamic Relations has stated:

“Based on the brutal nature of this crime, the past anti-religion statements of the alleged perpetrator, the religious attire of two of the victims, and the rising anti-Muslim rhetoric in American society, we urge state and federal law enforcement authorities to quickly address speculation of a possible bias motive in this case.”

Hicks is reportedly cooperating with authorities and more details may be released, according to police.
