she had a young daughter, Julie Adams. Burroughs and Kerouac got into trouble with the law for failing to report a murder involving Lucien Carr, who had killed David Kammerer in a confrontation over Kammerer's incessant and unwanted advances. This incident inspired Burroughs and Kerouac to collaborate on a novel titled And the Hippos Were Boiled in Their Tanks, completed in 1945. The two fledgling authors were unable to get it published, but the manuscript was eventually published in November 2008 by Grove Press and Penguin Books. During this time, Burroughs began using morphine and became addicted. He eventually sold heroin in Greenwich Village to support his habit. Vollmer also became an addict, but her drug of choice was Benzedrine, an amphetamine sold over the counter at that time. Because of her addiction and social circle, her husband immediately divorced her after returning from the war. With urging from Allen Ginsberg, and also perhaps Kerouac, Burroughs became intellectually and emotionally linked with Vollmer and by summer 1945, had moved in with Vollmer and her daughter. In spring 1946, Burroughs was arrested for forging a narcotics prescription. Vollmer asked her psychiatrist, Lewis Wolberg, to sign a surety bond for Burroughs' release. As part of his release, Burroughs returned to St. Louis under his parents' care, after which he left for Mexico to get a divorce from Ilse Klapper. Meanwhile, Vollmer's addiction led to a temporary psychosis that resulted in her admission to Bellevue Hospital, which endangered the custody of her child. Upon hearing this, Burroughs immediately returned to New York City to gain her release, asking her to marry him. Their marriage was never formalized, but she lived as his common-law wife. They returned to St. Louis to visit Burroughs' parents and then moved with her daughter to Texas. Vollmer soon became pregnant with Burroughs' child. Their son, William S. Burroughs Jr., was born in 1947. The family moved briefly to New Orleans in 1948. Mexico and South America (1950–1952) Burroughs fled to Mexico to escape possible detention in Louisiana's Angola state prison. Vollmer and their children followed him. Burroughs planned to stay in Mexico for at least five years, the length of his charge's statute of limitations. Burroughs also attended classes at the Mexico City College in 1950, studying Spanish, as well as Mesoamerican manuscripts (codices) and the Mayan language with R. H. Barlow.
