Former Hong Kong actress Sheree Lo Ming-chu died from a sudden heart attack on Friday morning. The news shocked many of her friends and supporters as the 47-year-old film star had been in good health with no signs of illness. Several of Lo’s relatives appeared sad after identifying the body at Victoria Public Mortuary in Kennedy Town on Saturday morning. Lo, who was previously known as Bonnie and was best remembered for her role in the 1980s popular comedy Happy Ghost , was found collapsed in her Residence Bel-Air apartment near Cyberport at around 3am on Friday. The star was certified dead from heart failure shortly after she was sent to Queen Mary Hospital for treatment. A police source close to the investigation said officers had picked up medication from her flat, including diet pills. “It is unclear if the tablets had triggered the heart attack. We need to wait for the autopsy report to figure it out,” the source said. The star’s uncle, Lo Kwok-wah, told the Chinese-language media that Sheree had been filming online movies lately and was trying to reduce weight for her latest role. The actress was last seen at Leon Lai’s concert in Central on April 29. Entering show biz at the age of just 15, Lo was a household name in the 1980s and early 90s. She made her screen debut in Raymond Wong Bak-ming’s 1984 comedy, Happy Ghost , which later became a big hit. Acting as a teen girl called Bonnie who befriends a scholar ghost, the young actress captured millions of hearts with her bubbly personalty. Together with co-stars Loletta Lee Lai-chun, Sandy Lamb Shan-shan and May Lo Mei-mei, the girls were widely known as the “Happy Girls” as the first generation of modern Hong Kong film stars. Lo quit the industry to study in Canada in 1988. She worked in finance when she returned to Hong Kong.
