Muslims hate Sikhs (who are a syncretist group).
However, unless this guy was a Chechen or something, it sounds to me like another white nutcase who saw them wearing turbans and thought they were Muslims. Remember a Sikh was killed and others were beaten after 9/11.
I don’t know why, because Muslims generally don’t wear anything that looks remotely like a Sikh turban.

Taking into consideration the perps deranged mind, not sure that level of detail is discernible nor meaningful to him.
