The FBI is investigating the killings of three Muslims to determine whether religious or ethnic hatred motivated the shooting in North Carolina, WCNC-TV reports.

The case remains under investigation by Chapel Hill police.

The bureau said it “opened a parallel preliminary inquiry to determine whether any federal laws were violated.”
