Karyn Kupcinet (March 6, 1941 – November 28, 1963) was an American actress who was found dead at her West Hollywood, California home, in the days following the JFK assassination. It has been theorized that her death, officially ruled a homicide, was connected to the assassination or was the result of an accidental fall, though her family have disputed such claims.
On the last day of her life, Kupcinet had dinner with future Lost in Space cast member Mark Goddard and his wife, Marcia Rogers Goddard, at their house on Coldwater Canyon Drive in Beverly Hills (near Mulholland Drive). She was due there at 6:30 pm, but arrived an hour late by taxicab. The couple said Kupcinet only toyed with her food during the meal. Marcia Goddard told two officers from the L.A. County Sheriff's Office that during dinner with Kupcinet "... her lips seemed numb. Her voice was funny. She moved her head at odd angles." The Goddards also noticed that her pupils were constricted. Mark Goddard told authorities that he confronted Kupcinet about her altered state during the meal, and she began to cry, putting her arm around him. At one point during the meal, Kupcinet told her friends an unsubstantiated story about a baby that had been abandoned on her doorstep earlier that day. At 8:30 pm, a taxicab arrived to take her home, and she promised to telephone the Goddards soon.
Kupcinet apparently went straight home after dining with her friends. She was visited by freelance writer Edward Stephen Rubin shortly afterward. The two were then joined by actor Robert Hathaway around 9:30 pm. They told detectives they watched TV, including The Danny Kaye Show, with Kupcinet. They all drank coffee until she fell asleep, sitting next to them on the couch. She awoke and went to her room. The men either turned the TV set off or simply lowered the volume (three days later it was still playing with a low volume), and made sure the door was locked behind them before departing at about 11:15 pm. Hathaway said he and Rubin returned to his place and were later joined by Kupcinet's boyfriend, Andrew Prine, who was also Hathaway's neighbor. The three young men watched television and talked until approximately 3:00 am.
The Goddards went to Kupcinet's apartment on November 30, after she failed to telephone the couple as promised. Mark Goddard stated that he had a "funny feeling" that something was wrong. Upon arriving at Kupcinet's apartment, the couple found her nude body lying on the couch. Mark Goddard initially assumed that she had died from a drug overdose.
Upon searching Kupcinet's apartment, police found prescriptions for Desoxyn, Miltown, Amvicel, and other medications. Authorities also found a note written by Kupcinet that reflected in some detail her emotions regarding issues in her life (i.e., parents, self-image, problems with boyfriend) and people she admired.
Coroner Harold Kade concluded that due to a broken hyoid bone in her throat, Kupcinet had been strangled. Her death was officially ruled a homicide.
