A trial court or court of first instance is a court in which trials take place. Such courts are said to have original jurisdiction.

A trial court of general jurisdiction is authorized to hear any type of civil or criminal case that is not committed exclusively to another court. In the United States, the United States district courts are the trial courts of general jurisdiction of the federal judiciary; each U.S. state has a state court systems establishing trial courts of general jurisdiction, such as the Florida Circuit Courts in Florida, the Superior Courts of California in California, and the New York Supreme Court in New York.

Not all cases are heard in trial courts of general jurisdiction. A trial court of limited jurisdiction is authorized to hear only specified types of cases. Trial courts of limited jurisdiction may be limited in subject-matter jurisdiction (such as juvenile, probate, and family courts in many U.S. states, or the United States Tax Court in the federal judiciary) or by other means, such as small claims courts in many states for civil cases with a low amount in controversy. Other trials do not take place in courts at all, but in quasi-judicial bodies or in administrative agencies with adjudicatory power created by statute to make binding determinations with simplified procedural practices, such as arbitration.

Jeffrey Lionel Dahmer (May 21, 1960 – November 28, 1994) was an American serial killer and sex offender. Dahmer murdered 17 men and boys between 1978 and 1991, with the majority of the murders occurring between 1987 and 1991. His murders involved rape, dismemberment, necrophilia and cannibalism. On November 28, 1994, he was beaten to death by an inmate at the Columbia Correctional Institution, where he had been incarcerated.

Dahmer was born in West Allis, Wisconsin, the son of Joyce Annette (née Flint) and Lionel Herbert Dahmer, an analytical chemist. Seven years later, his brother David was born. Joyce Dahmer reportedly had a difficult pregnancy with her elder son. When Jeffrey was eight years old, he moved with his family to Bath, Ohio. Dahmer grew increasingly withdrawn and uncommunicative between the ages of 10 and 15, showing little interest in any hobbies or social interactions. He biked around his neighborhood looking for dead animals, which he dissected at home (or in the woods near his home). In one instance, he went so far as to put a dog's head on a stake. Dahmer began drinking in his teens and was an alcoholic by the time of his high school graduation.
