Solving the Case & Afterwards
The St. Valentine's Day Massacre was never solved and is still a famous cold case. Although there are clear suspicions that Capone and his fellow gang members took their opportunity to kill rivals and committed this crime. After the St. Valentine's Day Massacre, Capone was under investigation for multiple different crime rings and when he failed to show up to Grand Jury after being subpoenaed, he was arrested when he finally showed up for court on contempt of court but then made bail. He was kept on a close watch list because of his bad reputation and his close affiliation with gangs and gang members. After this, he was arrested and served 9 months for carrying concealed weapons. After his release he was under investigation again for tax evasion, and he pled guilty to it on October 18, 1931. He was sentenced to 11 years in prison. He served part of his sentence in the penitentiary in Atlanta and the rest at Alcatraz, the most infamous prison. He was released after only 7 years but he had been struggling with syphilis for a lot of his life which had greatly deteriorated his health and eventually killed him due to complications on January 25, 1947.
