GREEN COVE SPRINGS, Fla. -- Three sheriff's deputies on the First Coast were involved in car accidents while on duty in the same weekend.

Two of those deputies were hit by other drivers.

A pair of connected crashes in Clay County claimed the lives of two drivers Saturday night.

"About 11 p.m. Florida Highway Patrol came and rang the doorbell," said Lillian Johnson, mother of one of the victims.

Johnson is mourning the loss of her 23-year-old daughter. Shanice Johnson was the driver of the silver Hyundai that was involved in a head-on collision on County Road 209.

Florida Highway Patrol is investigating which driver crossed the center line.

A second crash on the same road involved a Clay County Sheriff's deputy who was taking an arrestee to the jail. Troopers say the deputy hit Johnson's car after the initial accident.

Shanice Johnson's two-year-old was in the car with her, but was not hurt. The driver of the red Dodge Neon, Stacey Peternel, 37 was also pronounced dead. The Sheriff's Office has not identified the deputy involved.

There were two other deputy-involved accidents in the same weekend.

On Friday, the St. Johns County Sheriff's Office says a distracted driver rear-ended a St. Johns County Deputy working overnight in an unmarked car. Then, about 2 a.m. Sunday, another deputy with the same agency was rear-ended while stopped on the shoulder of State Road 13.

The Sheriff's Office says deputies are on the roads almost 12 hours a day, so it's not uncommon for there to be an officer involved accident, but it is unusual to have more than one in the same weekend.

The details of the fatal crash in Clay County are still being investigated.

The St. Johns County Sheriff's Office has a few safety tips for drivers: make sure everyone in the car is wearing a seat belt, steer clear of distracted drivers, and drive defensively.
