A nail salon manager was run over and killed in Las Vegas while chasing a customer skipping out on a $35 manicure bill, authorities said.

The suspect customer, whose credit card was declined, tried to drive away from Crystal Nails on Flamingo Road at 3:30 p.m. PT (6:30 p.m. ET) on Saturday as Ngoc Nguyen moved to catch her, witnesses and police told NBC affiliate KSNV.

No one had been arrested by Monday morning, Las Vegas police said.

"My wife ran out and tried to stop her, and then she rolled forward," Sonny Chung, the longtime boyfriend of Nguyen and the store's co-manager, told the Las Vegas Review-Journal.

Nguyen, 51, was rushed to University Medical Center of Southern Nevada and was pronounced dead at 4:40 p.m. PT (7:40 p.m. ET), a Clark County coroner's spokesperson said Monday. Nguyen was killed by "multiple blunt force injuries" and her death was classified as a homicide, the coroner said.

The suspect was driving a black Chevrolet Camaro, which police later said was reported stolen from a rental agency three weeks ago, police said.

"I tried to hold the car back but I'm not Superman," a tearful Chung said. "She ran off for $35 and killed my wife — $35 to run my wife over."

The stolen car was found at a nearby apartment complex on Saturday night.

"We do not believe the person who originally rented the car is the suspect," Las Vegas Metropolitan Police Lt. Ray Spencer told the newspaper.

Nguyen is survived by three daughters, 20, 25 and 28 and two grandchildren, 4 and 6, the family said.
