A Zephyrhills couple was killed Monday after a head-on collision with a Dodge Caravan carrying a family of four, the Hillsborough County Sheriff's Office said.
Charles Francis Viveros, 43, was driving north on a Harley-Davidson motorcycle on Morris Bridge Road near the Pasco-Hillsborough county line just before 7 p.m. Susan Lynn Ferrara, 38, was riding on the back.
Witnesses told investigators the bike's front tire began to wobble, causing the motorcycle to veer into the southbound lane and collide with the van.
Witnesses also said the van had "no time to take evasive action," according to a Sheriff's Office news release.
Viveros, who was not wearing a helmet, was thrown into the van's windshield. Ferrara was thrown to the pavement. Callaway said Ferrara had been wearing a helmet.
Both were dead at the scene when emergency crews arrived.
The driver of the Caravan, 20-year-old Cheryl Shambrea Farr, was taken by helicopter to St. Joseph's Hospital. Her husband, Curtis Farr, 21, and their two children - Kaylee, 1, and 2-year-old Dalyes - were taken there by ambulance, Callaway said.
Injuries to the Farr family were described as not life threatening.
Parts of Morris Bridge Road were closed to traffic as emergency responders from both counties helped investigate the crash scene.
