A member of a men’s chorus group unintentionally slammed into fellow chorists at the start of a Pride parade in South Florida, killing one member of the group and seriously injuring another, the group’s director said Sunday, correcting initial speculation that it was a hate crime directed at the gay community.

Wilton Manors Vice Mayor Paul Rolli and Fort Lauderdale Mayor Dean Trantalis said the early investigation shows it was an accident. The 77-year-old driver was taken into custody, but police said no charges have been filed and the investigation is ongoing.
