PAWTUCKET, R.I. (WPRI) — Members of the Rhode Island State Police are investigating after a horrific car crash claimed the lives of two Cumberland natives – a brother and his sister – on Saturday.

According to State Police, troopers responded to reports of a crash just before 4:30 p.m. on I-95 in the city of Pawtucket.

An investigation of the crash revealed a blue Toyota in the center lane of 95 southbound struck a silver Toyota that was traveling in the high-speed lane, causing it to lose control and hit the center median barrier. The silver Toyota then rolled into the northbound high-speed lane, where it was struck by a Chevrolet van.

The blue Toyota then veered right across all lanes and hit the jersey barrier on the right shoulder of 95 south.

The driver, a Pawtucket man, was transported to Fatima Hospital. His passenger was taken to Rhode Island Hospital with minor injuries, police said.

According to police, the driver of the silver Toyota, a 27-year-old woman from Cumberland, was transported to Memorial Hospital with non-life threatening injuries. Her husband, 28-year-old Derrick T. Joslyn, was pronounced dead at the scene.

His sister, 33-year-old Tiffany Joslyn, of Arlington, Virginia, was also killed in the crash.

According to State Police Lt. John Charbonneau, all people involved in the crash were wearing seatbelts.

Police said the driver of the Chevrolet, a Whitman, Massachusetts man, and his passenger, of Wrentham, Mass., were taken to Rhode Island Hospital with non-life threatening injuries.

Police are calling the crash a “freak accident.”

“I would say that you have to exercise caution. We’re talking an accident that’s 4:30 in the afternoon on a relatively clear day, the weather was not a factor, speed was not a factor as we know it. You just have to be careful,” Charbonneau said.

The crash remains under investigation.
