November 6th, 1982. 6:45 in the morning. Beverly Sunset Hotel, Los Angeles. A woman collapsed in the lobby, legs bruised, speech slurred, barely conscious. Hotel staff called paramedics. They rushed her to Cedar Sinai Medical Center. 3 days later, on November 9th, she was dead. Cocaine, Valium, whiskey.
The coroner ruled it an accidental overdose. Geraldine McGee was 46 years old. This was the woman who inspired Sharon Stone’s Ginger McKenna in Casino. The showgirl who married Vegas royalty had a complicated relationship with the mob’s most violent enforcer and was caught in the biggest casino skimming operation in American history. The movie made her iconic.
But Casino was a dramatization, not a documentary. The real story is more complex, more human, and in some ways even darker. This is the story of how beauty became survival, how desperation became addiction, and how one woman’s spiral through the Vegas underworld ended in a motel lobby 1,200 m from the strip. This is the real Gary McGee.
Not the Hollywood version, not the conspiracy theories, just the facts. But here’s what makes this story even more tragic. Just one month before Jerry died in that Los Angeles hotel, her ex-husband Frank Rosenthal survived a car bombing outside a Tony Roma’s restaurant in Vegas. The timing is haunting.
When you’re married to the man running casinos for the Chicago Outfit, when you’re involved with their enforcer, the line between coincidence and consequence gets very thin. Geraldine McGee was born May 16th, 1936 in Los Angeles. Her father, Roy McGee, worked as a mechanic. Her mother, Alice, struggled with mental health issues and spent time in psychiatric care.
The family had financial difficulties. Her sister Barbara later described their childhood as economically challenging with many of their clothes coming from neighbors. Young Jerry was acutely aware of their financial situation. She was determined to escape poverty. That determination shaped everything that came next.
At Vanise High School, Jerry was striking. 5′ 9 and 1/2 in tall, long legs, perfect posture, a face that turned heads. The guy who caught her eye was Lenny Mama, confident, street smart. They started dating when Gary was a teenager. After graduation in 1954, Gary worked various jobs. bank teller, secretary. She found the work unfulfilling.
Lenny encouraged her to enter beauty contests and dance competitions. She won several. Then in 1958, they had a daughter, Robin Mama. But Lenny didn’t marry Gary. Instead, around 1960, Jerry moved to Las Vegas with baby Robin. She was 24 years old, a single mother, starting over. Vegas in 1960 was booming. The Sands, the Dunes, the Stardust, the Riviera, all expanding, all hiring showg girls.
Jerry started as a cocktail waitress, possibly at the Tropicana. The tips were decent, but she realized the real opportunities were in the showrooms. She auditioned and was hired as a showgirl, performing in productions like the Foley’s Beer. The work paid well for the era, and she was good at it.
But Gary also learned another skill. She learned how to work the casino floor. High rollers would sometimes give chips to attractive women. It was part of the Vegas culture. Some show girls were more successful at this than others. Jerry became one of the most successful. She was charming, intelligent, and knew how to read people.
How much she actually made is unclear. The stories vary wildly, but she was certainly making more than her showgirl salary, and she was smart enough to save at least some of it. Her sister Barbara later confirmed that Gary had savings and investments during her Vegas years. That’s when Frank Rosenthal noticed her.

Around 1968, he was staying at the Tropicana, professional gambler, sports handicapper, brilliant with odds. Connected to people in Chicago. He was immediately attracted to Gary. Frank later said she was the most beautiful woman he’d ever seen and that she had incredible charm. Everyone who met her liked her. Frank pursued her.
He had competition. Gary was one of the most sought-a women in Vegas at the time. But Frank was persistent, wealthy, and powerful. Jerry, approaching her early 30s, agreed to date him. Frank later admitted that winning her over wasn’t easy. After about a year of dating, he proposed. Jerry said yes. May 4th, 1969. Caesar’s Palace. They got married.
The wedding was lavish with hundreds of guests and topshelf everything. Frank bought them a house at 972 Vegas Valley Drive in the exclusive Las Vegas Country Club area. They had a son, Steven. Then 3 years later, a daughter, Stephanie. From the outside, it looked like the perfect Vegas success story. On the inside, serious problems were developing.
Frank later admitted something painful. He said he knew Jerry didn’t love him when they got married, but he was so attracted to her that he thought he could build a good family and relationship anyway. He wasn’t under any illusions about why she married him. It was for security, stability, and the lifestyle he could provide.
Gary, for her part, had been candid with friends that financial security was a major factor in her decisions. That’s not unusual, but it’s not the foundation for a happy marriage. It was a transaction and transactions don’t sustain relationships when things get difficult. The problems started early. Frank believed Jerry was drinking too much and taking too many pills.
Jerry felt trapped and controlled. She’d gone from independence and excitement to suburban domesticity, and she struggled with it. Frank hired private investigators to follow her. Jerry accused him of affairs and being controlling. The marriage became volatile. There were fights. According to various accounts, including court documents and statements from both parties, there were incidents of physical violence on both sides.
Jerry’s sister, Barbara, later said that Jerry struggled particularly with the second pregnancy and had difficulty bonding with Stephanie, which added to the household tension. The violence was real. Both Frank and Jerry documented incidents. There was at least one occasion where Frank was injured in an altercation with one of Jerry’s ex-boyfriends, Johnny Hicks, at the Flamingo.
Frank, bloodied and furious, reportedly went back to his room, got a weapon, and went looking for Hicks. Friends intervened. Hicks was later shot to death outside his home in the same gated community where the Rosenthalss lived. Jerry suspected Frank was involved. Frank denied it. No one was ever charged. Then Tony Spelotro arrived in town.
Anthony the aunt Spelotro, childhood friend of Frank’s from Chicago, known enforcer. The FBI was watching him. Tony asked Frank if he could stay in Vegas. Frank agreed. It was a catastrophic decision. The FBI immediately intensified surveillance on Frank. Tony started calling himself Frank’s adviser and protector. The two were now publicly linked.
But Tony wasn’t just advising Frank. He began spending time with Jerry. The most disturbing incident involved their daughter Stephanie. Frank came home one day to find his wife and son gone. And his daughter Stephanie, still a toddler, left alone and restrained. Stephanie herself has confirmed in interviews that she was neglected and left alone during this period.
though she’s also been protective of her mother’s memory and insists Jerry wasn’t as out of control as portrayed. Frank got a call from Tony Spilotro saying he was with Jerry and that she wanted to talk. Frank met them at a location. Jerry was intoxicated. The confrontation was ugly. Frank eventually confronted Jerry directly about whether she was having an affair.
According to Frank’s account, she admitted she’d been involved with Tony Spelotro. Frank was devastated and enraged. He filed for divorce, but Jerry wasn’t done. In September 1980, during another heated argument, Jerry produced a handgun outside their home. Police were called. Nancy Spilotro, Tony’s wife, was also present and helped diffuse the situation by taking the gun from Jerry.
The image of two mob connected wives in a standoff with police is almost surreal. But before that incident in 1980, Jerry had been arrested in Los Angeles. She was found on Sunset Boulevard, apparently intoxicated and behaving erratically. Police took her to Harbor General Hospital in Torrance, where she was admitted to the psychiatric ward.
Frank flew down. The visit was difficult. Jerry was in crisis. Frank filed for divorce shortly after. He was granted custody of Steven and Stephanie. Gary received alimony of around $5,000 a month, her Mercedes, and jewelry. There was indeed an incident where Gary emptied their safe deposit box at a Vegas bank taking jewelry and valuables.
That scene was accurately depicted in casino. The divorce was finalized January 16th, 1981. Jerry moved back to California. She brought what money and assets she still had, but her addictions worsened. She fell in with people who took advantage of her deteriorating condition. Within months, her financial situation collapsed.
The money she’d saved was gone. The jewelry was sold or stolen. The woman who’d once lived in a mansion was now staying in cheap hotels, struggling with severe substance abuse. October 4th, 1982. Frank Rosenthal finished dinner at Tony Roma’s restaurant on East Sahara Avenue in Vegas. He walked to his 1981 Cadillac Elorado, got in, turned the key.
The car exploded. The blast was massive, but a metal plate under the driver’s seat, installed as part of the car’s design, likely saved his life. Frank survived with injuries, but walked away. No one was ever arrested or charged. The general assumption was that it was connected to Frank’s casino activities and his relationship with organized crime figures.
1 month and 2 days later, November 6th, 1982, early morning, Beverly Sunset Hotel on Sunset Boulevard, Jerry McGee was found in distress in or near the lobby. She had collapsed. Her legs showed bruising. She was barely conscious. Paramedics arrived. She had a combination of cocaine, alcohol, and tranquilizers, including Valium, in her system.
They rushed her to Cedar Sinai Medical Center. She never regained consciousness. On November 9th, 1982, she was pronounced dead. She was 46 years old. The Los Angeles County Coroner ruled it an accidental overdose. The combination of drugs and alcohol in her system was lethal. Frank, devastated and suspicious, reportedly paid for an independent autopsy.
The second examination confirmed the original ruling. Accidental overdose. The bruises on her legs were consistent with falling or collapsing, which can happen during an overdose. There was no evidence of foul play. But questions lingered. Jerry was broke. She was desperate. She’d been involved with dangerous people.
She knew about casino operations, the skimming, the outfit connections. And here’s a fact that emerged years later. In files released after Frank Rosenthal’s death in 2008, the FBI confirmed that Frank had been a longtime informant. He’d been providing information to federal authorities for years. This was shocking to many who knew him.
Whether Jerry knew about Frank’s FBI contact is unclear. Some sources have claimed Jerry also spoke to federal authorities, but this has never been definitively confirmed by released FBI documents. The idea that both were secretly informants is dramatic, but only Frank’s status is documented fact. Tony Spilotro didn’t survive much longer.
June 14th, 1986, Tony and his brother Michael were called back to the Chicago area. They believed it was for a meeting or a promotion. It was an execution. They were beaten to death. Their bodies were found buried in an Indiana cornfield about a week later. Tony was wearing only underwear. He was 48 years old.
The murders were later confirmed to be mob hits carried out because Tony had become too much of a liability with federal heat intensifying. Lenny MMA, Jerry’s first significant partner and Robin’s father stayed in Los Angeles. He kept a low profile. He died August 24th, 2013 at age 76 from natural causes. He outlived everyone in this story.
Frank Rosenthal left Las Vegas after the car bombing. He eventually settled in Florida where he ran a sports bar in Boca Raton and continued working as a handicapper. He died October 13th, 2008 of a heart attack. He was 79 years old. In 2013, he was postumously inducted into the sports betting hall of fame for his contributions to legalizing and professionalizing sports betting in Las Vegas casinos.
Despite everything, Frank never stopped talking about Jerry. In interviews late in his life, he still referred to her as the love of his life. Jerry’s children survived, but the trauma shaped their lives. Robin Mamer, now 67, lives in Orange County, California. She’s largely stayed out of the public eye, though she gave an interview to the Daily Mail in 2024.
In it, she said that Frank Rosenthal controlled the narrative about her mother for years, and that Jerry wasn’t the completely out of control person portrayed in Casino. Robin and Stephanie, Jerry’s daughter with Frank, are not close. They live relatively near each other but reportedly don’t have a relationship.
Stephanie Rosenthal is now 52. She’s a divorced single mother of twins. She was 9 years old when her mother died. She remembers the chaos of those years, including being left alone. But she’s also been fiercely protective of both her parents’ memories. In interviews, Stephanie has said her mother wasn’t the hardcore addict and party girl the movie showed.
She’s described her as someone who liked to have fun but was struggling with real problems. Stephanie has also defended her father, insisting he was a legitimate businessman, not a mobster. Former law enforcement officials who worked organized crime cases in Vegas during that era would strongly disagree with that characterization.
But Stephanie’s view is understandable. She’s defending her parents and trying to make sense of a childhood marked by violence, addiction, and loss. So, what’s the real story of Jerry McGee? She was intelligent, beautiful, and ambitious. She came from very little and built herself into one of the most recognizable figures in Las Vegas during the 1960s and ‘7s.
She was a talented showgirl and a shrewd operator who understood how to navigate the complex social ecosystem of casino culture. She made good money and saved at least some of it, showing financial intelligence. She was also someone who married for security rather than love, which set up a troubled foundation. She struggled with substance abuse.
She was involved in a volatile, sometimes violent marriage. She had an affair with a dangerous man. She was a mother who, by her own daughter’s accounts, could be loving, but also neglectful. When addiction took over, she lost everything in the end.
