Robert Desmond Meikle OBE (18 May 1923 - 8 February 2021), was an Irish botanist from the Royal Botanic Gardens, Kew. He was born 18 May 1923 in Newtownards, County Down, Northern Ireland).

Joseph Edward Duncan III (February 25, 1963 – March 28, 2021) was an American convicted serial killer and child molester who was on death row in federal prison in conjunction with the 2005 kidnappings and murders of members of the Groene family of Coeur d'Alene, Idaho. He was also serving 11 consecutive sentences of life without parole in conjunction with the same crimes as well as the 1997 murder of Anthony Martinez of Beaumont, California. Additionally, Duncan confessed to—but had not been charged with—the 1996 murder of two girls, Sammiejo White and Carmen Cubias, in Seattle. At the time of the attack on the Groene family, Duncan was on the run from a child molestation charge in Minnesota. He spotted Shasta and Dylan Groene playing outside as he drove past their house on Interstate 90. Born in Tacoma, Washington, Duncan had a criminal history dating to when he was 15 years old. In 1980, he was sentenced to 20 years in prison for sexually assaulting a boy in Tacoma and as a result had spent all but six years of his adult life in prison. He was paroled in 1994 but was returned to prison in 1997 for violating the terms of his parole. In May 2005, Kootenai County, Idaho, authorities discovered the bodies of Brenda Groene, her boyfriend, and her 13-year-old son in the family home near Coeur d'Alene. Authorities also noted that Groene's two other children were missing: Shasta, eight, and Dylan, nine. After an intense search for the two children, Shasta was found alive with Duncan at a restaurant in Coeur d'Alene nearly seven weeks later, and Duncan was arrested in conjunction with her kidnapping. When the authorities rescued Shasta, she told them that Duncan said that he was bringing her back to her father because Duncan had changed his mind about killing her. She said that Duncan stated that she taught him how to love. Dylan's remains were found days later in a remote area near St. Regis, Montana. Duncan was subsequently charged with murdering Dylan as well as the three victims at the Coeur d'Alene home. During his incarceration, authorities connected Duncan with the unsolved murders of Anthony Martinez in California and two girls in Seattle, which all occurred during Duncan's parole from 1994–1997. Of those murders, Duncan was only charged in the California case. In all, Duncan was convicted in Idaho for kidnapping and murdering the three victims in Coeur d'Alene, for which he was given six life sentences; in federal court for kidnapping Shasta and Dylan Groene and murdering Dylan, for which he was given three death sentences and three life sentences; and in the state of California for kidnapping and murdering Martinez, for which he was given two life sentences. In March 2021, it was reported that Duncan was suffering from terminal brain cancer. Court filings revealed he underwent brain surgery in October 2020, after being diagnosed with glioblastoma — stage IV brain cancer. He declined treatment from either chemotherapy or radiation therapy. In November 2020, medical staff at the Federal Bureau of Prisons estimated he had between six and twelve months left to live. He died on March 28, 2021, at the age of 58.
