He was murdered by Gaius Servilius Glaucia during the disturbances that rocked Rome during the violent uprising and suppression of Lucius Appuleius Saturninus.
During his tribunate, he accused the consul Lucius Calpurnius Bestia, the senator Marcus Aemilius Scaurus and other aristocrats of accepting bribes from King Jugurtha.
[1] Memmius served as praetor sometime between in 107 and 102 BC,[2] and this was followed by the proconsular governorship of Macedonia.
[3] Then, Marcus Aemilius Scaurus prosecuted Memmius with the charge of extortion.
It has been speculated that, primarily due to Cicero describing him as consul designatus,[5] Memmius was actually elected Consul in the disrupted elections of 99 BC, and was killed after his successful candidature was announced in the Roman Forum.
