A driver slammed into spectators Saturday evening at the start of a Pride parade in South Florida, killing one person and seriously injuring another, authorities said

The pickup truck driver acted like he was part of the Wilton Manors Stonewall Pride Parade but then suddenly accelerated when he was told he was next, crashing into the victims, Fort Lauderdale Mayor Dean Trantalis said, according to WSVN-TV. Wilton Manors is just north of Fort Lauderdale.
