Victims' father convinced killing of three US Muslims was a hate crime

Police and the FBI are trying to determine whether the killing of three Muslims during a neighbourhood parking and noise dispute was a hate crime.

Craig Hicks (aged 46), who describes himself as a "gun toting" atheist, appeared in court charged with the first-degree murder of Deah Barakat (aged 23), his wife Yusor Mohammad, 21, and her sister Razan Mohammad Abu-Salha (aged 19), in Chapel Hill, North Carolina, on Tuesday.
