Before the murder, Peter considered suicide by throwing himself from a building, and Katarina called a friend to calm him down. Peter came back inside, where he quarreled with Katarina. The two shared an open relationship, as Katarina seeks other lovers. Peter claimed he is the one who knows how to sexually satisfy Katarina. Katarina responded she sometimes had orgasms with Peter, but also that she sometimes faked them and left the bedroom to masturbate, and that on other occasions she only had small convulsions.
