Lethal injection in the context of Capital punishment in China

San Quentin Rehabilitation Center (SQ), formerly known as San Quentin State Prison, is a California Department of Corrections and Rehabilitation state prison for men, located north of San Francisco in the unincorporated place of San Quentin in Marin County.

Established in 1852, and opening in 1854, San Quentin is the oldest prison in California. The state's only death row for male inmates, the largest in the United States, was located at the prison. Its gas chamber has not been used since 1993, and its lethal injection chamber was last used in 2006. The prison has been featured on film, radio drama, video, podcast, and television; is the subject of many books; has hosted concerts; and has housed many notorious inmates.

The Sisak concentration camp was a concentration and transit camp located in the town of Sisak, in the Axis puppet state the Independent State of Croatia (NDH), from 1941 to 1945, during World War II. It consisted of two sub-camps, Sisak I and Sisak II. The former was used to intern adults destined for forced labour in the Reich and was established in 1941, while the latter was used to detain unaccompanied Serb—and to a lesser extent, Jewish and Roma—children who had been separated from their parents over the course of the conflict. Sisak I was operated by the Germans, whereas Sisak II was administered by the Ustaše, with some German gendarmes guarding its perimeter. The latter became operational in July–August 1942, receiving a group of children who had previously been detained at Mlaka.

Living conditions at the children's camp were poor, leading to a high mortality rate. According to survivors, some children were killed by being given poisoned milk or gruel laced with caustic soda. On other occasions, camp commander Antun Najžer administered children with lethal injections. Thousands of children were saved from the camp as a result of rescue efforts spearheaded by the humanitarian Diana Budisavljević and the local communist underground. Sisak II was dissolved in January 1943. The exact number of children who perished there is unknown, but estimates range from 1,160 to 1,600, largely as a result of starvation, thirst, typhus and neglect. In April 1944, the Germans ceded control of Sisak I to the Ustaše. It was shut down in January 1945 and its remaining inmates were dispatched to Jasenovac.

Capital punishment is a legal penalty in the U.S. state of Ohio, although executions have been suspended indefinitely by Governor Mike DeWine until a replacement for lethal injection is chosen by the Ohio General Assembly. The last execution in the state was in July 2018, when Robert J. Van Hook was executed via lethal injection for murder.

Pentobarbital (US) or pentobarbitone (British and Australian) is a short-acting barbiturate typically used as a sedative, a preanesthetic, and to control convulsions in emergencies. It can also be used for short-term treatment of insomnia but has been largely replaced by the benzodiazepine family of drugs.

In high doses, pentobarbital causes death by respiratory arrest. It is frequently used for veterinary euthanasia, and is used by some US states and the United States federal government for executions of convicted criminals by lethal injection. In some countries and states, it is also used for physician-assisted suicide.

Sodium thiopental, also known as thiopental sodium or thiopentone and sold under the brand name Pentothal, is a rapid-onset short-acting barbiturate general anesthetic. It is the thiobarbiturate analog of pentobarbital, and an analog of thiobarbital. Sodium thiopental is a therapeutic alternative on the World Health Organization's List of Essential Medicines. It was the first of three drugs administered during most lethal injections in the United States until the US division of Hospira objected and stopped manufacturing the drug in 2011, and the European Union banned the export of the drug for this purpose. Although thiopental abuse carries a dependency risk, its recreational use is rare.

Sodium thiopental is well-known in popular culture, especially under the name "sodium pentothal," as a "truth serum," although its efficacy in this role is questioned.

Clarence Ray Allen (January 16, 1930 – January 17, 2006) was an American criminal, gang leader, and proxy killer who was executed in 2006 at the age of 76 by lethal injection at San Quentin State Prison in California for the murders of three people. Allen was the second-oldest inmate at the time to be executed in the United States since 1976.

Allen was already serving a life sentence for one murder when he was convicted of organizing the killing of three more people from prison, including a witness who had testified against him in the previous murder. Allen also claimed to have murdered two other people in Nevada.
