Carl Panzram ( June 28 , 1891 -- September 5 , 1930 ) was an American serial killer , rapist , arsonist and burglar . In jailhouse confessions and his autobiography , he claimed that he had committed 21 murders -- most of which could not be corroborated -- and over 1 , 000 rapes and sodomies . After a series of imprisonments and escapes , he was executed in 1930 for the ___MASK74___ of a prison employee at Leavenworth Federal Penitentiary . Manslaughter is a legal term for ___MASK81___ considered by law as less culpable than ___MASK74___ . The distinction between ___MASK74___ and manslaughter is sometimes said to have first been made by the Ancient Athenian lawmaker Draco in the 7th century BCE . ___MASK74___ is the unlawful killing of another human without justification or valid excuse , especially the unlawful killing of another human being with malice aforethought . This state of mind may , depending upon the jurisdiction , distinguish ___MASK74___ from other forms of unlawful homicide , such as manslaughter . Manslaughter is a killing committed in the absence of " malice ", brought about by reasonable provocation , or diminished capacity . " Involuntary " manslaughter , where it is recognized , is a killing that lacks all but the most attenuated guilty intent (" mens rea "), recklessness . A serial killer is a person who typically murders three or more people , usually in service of abnormal psychological gratification , with the murders taking place over more than a month and including a significant break ( a " cooling off period ") between them . Different authorities apply different criteria when designating serial killers ; while most set a threshold of three murders , others extend it to four or lessen it to two . The Federal Bureau of Investigation ( FBI ), for example , defines serial ___MASK11___ as " a series of two or more murders , committed as separate events , usually , but not always , by one offender acting alone ". ___MASK81___ refers to one human being ___MASK11___ another . Homicides can be divided into many overlapping types , including ___MASK74___ , manslaughter , justifiable homicide , ___MASK11___ in war , euthanasia , and ___MASK73___ and abortion , depending on the circumstances of the death . These different types of homicides are often treated very differently in human societies ; some are considered crimes , while others are permitted or even ordered by the legal system . Malice aforethought was the " premeditation " or " predetermination " ( with malice ) that was required as an element of some crimes in some jurisdictions and a unique element for first - degree or aggravated ___MASK74___ in a few . Insofar as the term is still in use , it has a technical meaning that has changed substantially over time .
