Bilal Musa and Susan Ibrahim

Bilal Musa Muhammad (; 1972 – December 7, 2000) and Susan Ibrahim Tawfiq (; May 26, 1971 – November 5, 2001) were Jordanian serial killers who robbed and murdered twelve people around Jordan from 1994 to 1998. Musa was convicted, sentenced to death and executed for the murders in 2000, while Ibrahim died behind bars a year later.

Considered the country's first serial killers, some doubt has been cast on whether they were truly responsible for all of the murders, with allegations of them being framed by the police.

Early lives Bilal Musa Muhammad was born in 1972 in Zarqa into a poor family with twelve children. Little is known about his upbringing, but starting at age 14, Musa became an apprentice house painter. After graduating from university with a degree in accounting, he moved to Amman, where he found employment for a marketing company for tourist resorts in the Sweifieh district.

Susan Ibrahim Tawfiq was born on May 26, 1971, also in Zarqa. Much of her background is also unknown, but by the early 1990s, her family was residing in the house opposite of the Musa family.

Murders Modus operandi The exact circumstances behind why the couple started killing are unknown. Presenting themselves as real estate agents or salespeople, they visited random homes in the early mornings and would make up an excuse as to why they were there. 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. 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 by journalists and the police, who pointed out that Al-Khatib had claimed that he had killed Al-Khayyat by beating him to death with a hammer, while an autopsy had definitively determined that he had been stabbed with a knife. This, and the lack of strong evidence of a forced confession, has led doubts to the credibility of the innocence theory.
