Nancy Argentino's sister Lorraine spoke to INSIDE EDITION after Jimmy Snuka was charged in the cold-case murder.
Wrestling legend Jimmy "Superfly" Snuka is charged in his girlfriend's death 32 years ago after her sister, Lorraine Salome, waged a long battle to get justice.

Lorraine told INSIDE EDITION: "We realized this is ridiculous. We have to do something about it."
Snuka rose to fame in the 1980s with his trademark "Superfly Splash."
In 1983, his girlfriend Nancy Argentino was found bruised and gasping for air in their motel room in Allentown, Pennsylvania.
The 23-year-old died the next day. Authorities say an autopsy found she suffered from a fractured skull and 39 contusions and abrasions.
But the investigation went nowhere. It languished in the cold case file.
The case has haunted the Hall of Fame wrestler for his entire career and Lorraine never stopped pushing prosecutors to reopen the investigation.
She said: "We got the word out. Then we contacted the D.A. and said: 'Hey, look at all the things going on here. Can't you do something about it?'"
Lorraine was working at her flower shop in Manhattan when she got the call she had been waiting for more than three decades. The District Attorney from Pennsylvania told her Snuka was going to be charged with her sister's murder.
"I felt that at least someone will be held accountable for this," she said.
Her husband, Richard, tearfully told INSIDE EDITION: "Let's see whose life is extinguished now."

The grand jury report says Snuka gave different explanations for Nancy’s injuries.
At first he said she fell as they were "fooling around outside [the] motel room." Later he said it happened when they "stopped on the road to go to the bathroom."
In his autobiography, Superfly, published three years ago, Nancy Argentino's death was still weighing on his mind. He continued to deny wrongdoing, writing: "I didn't hurt Nancy.'
INSIDE EDITION's Ann Mercogliano asked Lorraine: "If Jimmy was here right now, what would you say to him?"
She said: "I would ask him: 'Why did you kill my sister? She apparently loved you and cared for you. She didn't deserve this. Why did you do this to her?'"
Snuka could face 20 to 40 years in prison if convicted.
