According to police, a blue GMC Yukon swerved over the center divider on White Avenue and traveled into southbound traffic, hitting a gold Ford Ranger head-on.
They reported that the male or female child was in the gold truck sitting sideways in a jumpseat behind the driver and most likely suffered blunt force trauma from the impact.
