WATCH: Parents of slain USC student push for laws to make ride-sharing safer

COLUMBIA, S.C. — For the first time, the parents of a University of South Carolina student -- killed after she got into the wrong car -- shared their story.

Police said Samantha Josephson, 21, was killed last month by a man who she thought was her Uber driver.

Video shows Josephson's last moments alive as she got into the back of a vehicle around 2 a.m. in Columbia's Five Points entertainment district. Her body was discovered less than 24 hours later in a field 90 miles away.

Authorities said the man behind the wheel, 24-year-old Nate Rowland, was impersonating an Uber driver and has now been charged with murder and kidnapping.

Josephson's parents remembered their daughter and shared thoughts on changes to keep riders safe Monday morning as guests on "Good Morning America."

"She was a fabulous young woman, kind -- a best friend to everyone," said Josephson's mom, Marci.

Josephson's dad, Seymour, believes all cars used in the ride-sharing industry should be required to have a front license plate and a confirmation barcode for riders to scan before getting in the car.

Marci said simply asking the driver "What's my name?" before stepping into the car could save the lives of many.

"It has to be automatic -- like putting on a seatbelt. You have to ask, 'What's my name?' because it could be anyone," said Marci.

Lawmakers in both Carolinas are working on bills to make ride-sharing apps safe.

In South Carolina, lawmakers are in the process of passing the "Samantha L. Josephson Ridesharing Safety Act," which would require drivers to put illuminated signs on their vehicles identifying their company.

In addition to that, North Carolina's bill would require drivers to identify the company they're with and turn in their lighted signs 10 days after leaving the job. Companies would also have to keep records on both drivers and riders.

"We're all telling our kids not to get into cars with strangers and what do we do -- get in the car with strangers," said Seymour.

Investigators said they found Josephson's blood in Rowland's car and the child lock had been activated so the back doors could only be opened from the outside.
