extracted from the letter belonged to Bilal Musa. Soon after this revelation, the couple's house was raided, but police found nobody inside. Another letter was located in which it was made apparent that they had left Jordan on September 21, ostensibly for a work assignment in Benghazi, Libya. The couple were traced to a harbor in Sallum, Egypt, and with the help of Interpol and Libyan authorities, both were apprehended and returned to Jordan via Tunisia. Upon interrogation, the spouses admitted their responsibility for the crime, but Musa attempted to justify it by claiming that Jalil had attempted to assault his wife. After a forensic examination determined that both were sane and able to stand trial, Musa and Ibrahim were charged with the twelve murders attributed to them. According to psychologists, there was no real motive behind the crimes, but some suspected that it was simply Musa having developed an addiction to killing. Prosecution, sentences, and fates Musa and Ibrahim were eventually put on trial for the twelve murders, but they denied responsibility for all except Jalil's killing, claiming that they had been coerced into confessing by the police. Their public defender attempted to convince the court that Jalil's killing was done out of righteous self-defense, but this suggestion was rejected and both were found guilty - Musa on all counts, while Ibrahim solely for Jalil's murder. The former was sentenced to death, while Ibrahim initially also received the same penalty, later commuted to life imprisonment with hard labor due to her pregnancy. All of Musa's subsequent appeals were rejected, and on December 7, 2000, he was hanged at the Swaqa Prison in Amman in the presence of the Public Prosecutor, security officials and a doctor. Less than a year later, on November 5, 2001, Ibrahim died of a suspected heart attack while incarcerated. Claims of innocence Five years after Musa's execution, his brother and a team of investigators put forward the theory that he and Ibrahim were actually innocent of all murders except that of Jalil. They claimed that another murderer who had been arrested in 2004, Zuhair Al-Khatib, had confessed to killing Al-Khayyat and given a detailed confession of how he had carried out. In addition to this, they reiterated the claims that the spouses had been forced and threatened into confessing by the authorities, who supposedly just wanted to clear unsolved murder cases. These claims were refuted
