For eight long months in 1980, a single question followed Larry Hagman everywhere he went. Bookmakers took money on it, and even a sitting president joked about it on the campaign trail. Who shot J.R. Ewing? The answer finally came on Dallas on Friday, November 21, 1980, in an episode called “Who Done It,” and it was Kristin Shepard, J.R.’s scheming sister-in-law and former mistress.
Kristin was played by Mary Crosby, the daughter of Bing Crosby and actress Kathryn Grant, who was just 21 when the secret came out. She shot J.R. in a fury after their affair went sour, and she very nearly let her own sister take the blame. Getting there was a much stranger story, because the people who made the show spent that summer guarding a secret that some of them did not yet know themselves.
How Did One Gunshot Become A National Obsession?

The shot rang out on March 21, 1980, in the third-season finale, “A House Divided.” J.R. was working late in his office at Ewing Oil when an unseen figure fired twice and left him crumpled on the floor. The camera never showed a face, and by then J.R. had given half of Texas a reason to want him dead.
The twist began as a scramble. According to the American Press, CBS ordered two extra episodes at the last minute to close out the season, and the producers needed a big finish. They had not even settled on the shooter when they decided J.R. would be shot. Hagman put it more bluntly years later, telling Katie Couric for CBS News that the plan amounted to, “Let’s just shoot the SOB and figure it out later.” Asked if it was all a happy accident, he answered, “Oh, absolutely.”
By summer, “Who Shot J.R.?” was printed on T-shirts across the country, according to History.com. The man everyone was talking about had other things on his mind, though, and they had a lot to do with money.
Why Was Larry Hagman Fighting For His Job That Summer?
Hagman knew exactly what the cliffhanger had done to his value. J.R. merchandise was selling everywhere, and the actor wanted his share. “Everyone was making a windfall from J.R. except me,” he wrote in his 2001 memoir Hello Darlin’, as quoted by the Associated Press. He threatened to walk away unless his contract was reworked, and after months of tense talks the AP reported that he got his asking price of $100,000 an episode.
It was a gamble, because a character lying in a hospital bed can always be written out. Hagman held his ground anyway. Asked by Couric whether his ego or his paycheck was bigger at that point, he laughed, “It was about half and half.”
Then a second delay landed, one nobody at Dallas could negotiate away. A Screen Actors Guild strike shut down television production that summer, according to History.com, and the American Press reported that it pushed the networks’ fall season into November. CBS filled the gap with reruns, and the mystery stretched out by roughly three more months.
What Did ‘Who Done It’ Actually Reveal?

When the new season finally began, the writers made viewers wait three more episodes. Sue Ellen, played by Linda Gray, was arrested after her fingerprints turned up on the gun, and for a while it looked as though J.R.’s long-suffering wife had finally snapped.
The truth came out in the fourth episode. Sue Ellen pieced together that the gun had last been with her at Kristin’s condo, where her sister had poured her drinks until she passed out. Kristin then shot J.R. and planted the gun in Sue Ellen’s closet. UPI described her motive that night as a woman scorned. J.R. had promised to leave Sue Ellen and marry her, and when Kristin pressed him, he had her hit with a phony prostitution charge. Cornered, she played one last card and told J.R. she was carrying his child, warning that if he sent her to jail, his baby would be born there. J.R. let her leave town.
America was watching. The episode drew a 53.3 Nielsen rating and a 76 share, with an estimated 83 million viewers in the United States alone, according to History.com, and some later counts ran past 90 million. UPI reported that CBS charged sponsors $500,000 a minute for commercial time. It stood as the most-watched episode in American television until the M*A*S*H finale passed it in 1983, and it still ranks second.
Did The Cast Know Who Pulled The Trigger?
To keep the answer from leaking, the producers turned the shooting into a group project. “Everybody took a shot at [J.R.],” Patrick Duffy recalled at a 2023 cast reunion with Entertainment Tonight. “I mean, I shot J.R. I think Linda shot J.R. Jim Davis shot him.” Gray chimed in, “Yeah, we all did.” Duffy called it “the cover story,” and Steve Kanaly, who played Ray Krebbs, explained the real reason it worked: “They hadn’t decided who it was going to be [at the time] and that was the idea.”
The secrecy paid off around the world. Kanaly said fans called him for the answer because they had money riding on it in Las Vegas and Europe, and Audrey Landers was pestered about it while recording in Europe. Hagman himself stonewalled royalty. When the Queen Mother asked him who did it, he told CBS News, his reply was, “No ma’am, not even you.” Back home, President Jimmy Carter reportedly joked at a Dallas fundraiser that he had come “to find out confidentially who shot J.R.”
Hagman’s teasing of his co-stars was a big part of the fun on that set, and Gray has shared plenty about the pranks Hagman pulled during their kissing scenes. But one cast member’s memory of the secret has never quite lined up.
What Did Mary Crosby Really Know?

Over the years, Mary Crosby has told the story the way fans love to hear it, as a surprise she learned along with everyone else. “I knew when everybody else knew,” she said in 2015, on the reveal’s 35th anniversary, as reported by the American Press. “I was thrilled, and spooked. I knew that it would change things, and it did.”
The night the episode aired, though, the 21-year-old gave UPI a slightly different version. “It came as a surprise to me,” she said, before adding, “We shot four endings but I had a pretty good idea Kristin was the guilty one.” So the actress who pulled the trigger may have guessed her own secret before the rest of America did, and she kept it anyway.
Larry Hagman went on playing J.R. until Dallas ended in 1991 and returned for TNT’s revival. He died of complications from cancer on November 23, 2012, at 81, and the revival killed off J.R. a few months later. Crosby, now 67, has made peace with being the answer to one of TV’s most famous questions. “Being the one who shot J.R. made me a trivia question,” she told CBS News. “And I’m really big in really small countries.”
