said that the exact cause of death could not be determined, but sleep apnea and the buildup of fatty tissue on the walls of arteries were among the contributing factors. A full report from June 19, 2017, stated that Fisher had cocaine in her system, as well as traces of heroin, other opiates, and MDMA. The report also stated that the investigation was unable to determine when she had taken the drugs and whether they contributed to her death. Her daughter stated that Fisher "battled drug addiction and mental illness her entire life. She ultimately died of it. She was purposefully open in all of her work about the social stigmas surrounding these diseases.... I know my Mom, she'd want her death to encourage people to be open about their struggles." On December 28, 2016, the day after Fisher's death, her mother, Debbie Reynolds, had a stroke at the home of her son, Todd, where the family was planning Fisher's burial arrangements. She was taken to Cedars-Sinai Medical Center, where she died later that afternoon. According to Todd, Reynolds had said, "I want to be with Carrie" immediately before she had the stroke. On January 5, 2017, a joint private memorial was held for Fisher and Reynolds. Fisher was cremated while her mother was entombed. A portion of her ashes were laid to rest beside Reynolds in a crypt at Forest Lawn Memorial Park in Hollywood Hills. The remainder of those ashes are held in a giant novelty Prozac pill. In the absence of a star for Fisher on the Hollywood Walk of Fame, fans created their own memorial using a blank star. Along with flowers and candles, words put on the blank star read, "Carrie Fisher / May The Force Be With You Always / Hope". Fans also gathered at the Yoda Fountain outside the Lucasfilm offices in San Francisco. In the video game Star Wars: The Old Republic, thousands of fans paid tribute to Fisher by gathering at House Organa on the planet Alderaan where Fisher's character in Star Wars resided. Lightsaber vigils and similar events in Fisher's honor were held at various Alamo Drafthouse Cinemas theaters and other sites. On January 6, 2017, the lights on Broadway in Manhattan were darkened for one minute in honor of Fisher and her mother. Fisher and Reynolds were also both featured in the 89th Academy Awards In Memoriam segment. On
