Eleanor "Lori" Nathan was denied parole this week for the second time since her 1983 convictions. Here is a timeline of the case:
Nov. 29, 1973: Gregory Alan Teasdale, a 21 month-old boy, dies of abdominal injuries that a prosecutor says were inflicted by Nathan at her South San Francisco home. Gregory's pediatrician misdiagnoses the death as resulting from natural causes.
Spring 1974: A 2-year-old boy is twice hospitalized for abdominal injuries he allegedly suffered at Nathan's home and undergoes surgery.
April 1975: Julia Cosmides, 3, undergoes emergency surgery for a ruptured pancreas and a damaged spleen after Nathan abuses her in South San Francisco, according to a prosecutor. San Mateo County Child Protective Services investigates Nathan, but the investigation does not result in a prosecution. Nathan tells San Mateo County authorities that she is moving to Concord and will not operate another day care center.
August 1979: A 15-month-old boy is hospitalized with abdominal injuries after only one day in Nathan's Clayton home.
August 1980: A 9-month-old boy is hospitalized for nine days for retinal hemorrhages in both eyes after spending one week at Nathan's Clayton home. He is permanently blinded in one of the eyes. Not knowing the source of his injuries, his parents return him to Nathan's care the next spring.
November 1980: A 4-year-old boy is hospitalized and undergoes abdominal surgery for blunt force trauma inflicted by Nathan.
March 18, 1981: Matthew Cromwell, an 11-month-old Pittsburg child and client at Nathan's day care on Mt. Whitney Way in Clayton, dies of abdominal injuries inflicted by Nathan.
March 19 to 23: Pittsburg police question Nathan.
May 26: Pittsburg police cease actively investigating Matthew's death.
Sept. 18: A 14-month-old Contra Costa County boy is hospitalized with abdominal injuries. His pediatrician notices similarities between his injuries and those that killed Matthew Cromwell and notifies police.
Sept. 24: State shuts down Nathan's Clayton day care. Sheriff's Office begins investigating Nathan.
Nov. 30: Nathan is arrested on suspicion of murder and child abuse.
Sept. 6, 1982: Nathan stands trial in Sacramento County, where the trial was moved because of extensive publicity surrounding the case. It is the last time that a Contra Costa County case was moved to another venue because of high publicity.
Jan. 13, 1983: Jurors find Nathan guilty of first-degree murder in Matthew Cromwell's death, 18 counts of felony child abuse, 12 counts of misdemeanor child abuse and seven counts of causing great bodily injury. The jury also found her guilty of one count of mayhem for shaking or choking a 9-month-old boy, causing brain hemorrhaging and permanent blindness in one eye.
Feb. 10, 1983: Nathan sentenced to 44 years to life in state prison
July 26, 2007: Nathan is denied release at her first parole hearing at California Institution for Women in Corona.
July 2, 2013: Nathan is denied parole for a second time in Corona. She's due before the parole board again in 2018, when she will be 71.
