Ariel Castro abandoned his love life in order to successfully hold his victims hostage "without any interruption," prosecutors said in a sentencing memorandum released Wednesday.
The document, which recounts the physical, sexual, and emotion abuse carried out by Castro on three Ohio women, also reveals details of the 53-year-old's personal life.
For instance, Castro rarely allowed relatives to visit his home, and when he did he insisted that guests "stay in the kitchen." The document describes Castro as a private, removed individual who set boundaries for the people around him.
Prosecutors outlined Castro's romantic life, which they say he abandoned around the same time he kidnapped his victims. The last intimate relationship Castro had was with a woman named Lilian Roldan, who prosecutors say was the defendant's girlfriend.
"The Defendant broke all ties with her in 2003 in order to successfully undertake kidnapping of the victims without any interruption by his social connections," prosecutors said.
The victims -- Amanda Berry, Gina DeJesus or Michelle Knight -- disappeared individually between 2002 and 2004.
Prosecutors added that the defendant had "no credit history whatsoever" and mostly dealt in cash.
