"JonBenét Patricia Ramsey (August 6, 1990 – December 25, 1996) was an American child beauty queen who was killed in her family's home in Boulder, Colorado. A lengthy handwritten ransom note was found in the house, and JonBenét's father John found her body in the basement of their house about eight hours after she had been reported missing. She sustained a broken skull from a blow to the head and had been strangled; a garrote was found tied around her neck. The autopsy report stated that the official cause of death was "asphyxia by strangulation associated with craniocerebral trauma." Her death was ruled a homicide. The case generated nationwide public and media interest, in part because her mother Patsy Ramsey (herself a former beauty queen) had entered JonBenét in a series of child beauty pageants. The crime is still unsolved and remains an open investigation with the Boulder Police Department.
The police initially suspected that the ransom note had been written by JonBenét's mother, and that the note and appearance of the child's body had been staged by her parents in order to cover up the crime. However, in 1998, the District Attorney said that due to a new DNA analysis, none of the immediate family members were under suspicion for the crime. Also in 1998, the police and the DA both said that JonBenét's brother Burke, who was nine years old at the time of her death, was not a suspect. The Ramseys gave several televised interviews but resisted police questioning except on their own terms. In October 2013, unsealed court documents revealed that a 1999 grand jury had recommended filing charges against JonBenét's parents for permitting the child to be in a threatening situation. John and Patsy were also accused of hindering the prosecution of an unidentified person who had "committed ... the crime of murder in the first degree and child abuse resulting in death". However, the DA determined that there was insufficient evidence to pursue a successful indictment.
In 2002, the DA's successor took over investigation of the case from the police and primarily pursued an alternative theory that an intruder had committed the killing. In 2003, trace DNA that was taken from the victim's clothes was found to belong to an unknown male; this discovery induced the DA to send the Ramseys a letter of apology in 2008, declaring the family "completely cleared." In February 2009, the Boulder police took the case back from the DA and reopened the investigation.
Media coverage of the case has focused on JonBenét's brief beauty pageant career, as well as her parents' wealth and the unusual evidence found in the case. Media reports have also questioned how the police handled the case. Ramsey family members and their friends have filed defamation suits against several media organizations..."

"The Golden State Killer is a serial killer, rapist, and burglar who committed at least 13 murders, more than 50 rapes, and over 100 burglaries in California from 1974 to 1986. He is believed to be responsible for three crime sprees throughout California, each of which spawned a different nickname in the press before it became evident that they were committed by the same person.
In the Sacramento area he was known as the East Area Rapist, and was linked by modus operandi (MO) to additional attacks in Contra Costa County, Stockton, and Modesto. He was later known for his southern California crimes as the Original Night Stalker. He is suspected to have begun as a burglar (the Visalia Ransacker) before moving to the Sacramento area, based on a similar MO and circumstantial evidence.
During the investigation, several suspects have been cleared through DNA evidence, alibi, or other investigative methods. In 2001, DNA testing indicated that the East Area Rapist and the Original Night Stalker were the same person and he was known as the EAR/ONS. The FBI and local law-enforcement agencies held a news conference on June 15, 2016, to announce a renewed nationwide effort, offering a US$50,000 reward for his capture. The case was a factor in the establishment of California's DNA database, which collects DNA from all accused and convicted felons in California and has been called second only to Virginia's in effectiveness in solving cold cases. To heighten awareness that the uncaught killer operated throughout California, crime writer Michelle McNamara coined the name "Golden State Killer" in early 2013..."
