Suetonius states that Nero committed suicide in Suetonius: The Lives of Twelve Caesars, Life of Nero 49; Sulpicius Severus, who possibly used Tacitus' lost fragments as a source, reports that it is uncertain whether Nero committed suicide: Sulpicius Severus, Chronica II.29, also see T.D. Barnes, "The Fragments of Tacitus' Histories", Classical Philology (1977), p. 228.
