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. Having fallen in love with her, Musa constantly tried to court and talk to Ibrahim, despite the fact she was already married to a cousin of hers. Her marriage did not last long and she eventually divorced, allowing her to get into a relationship with Musa and the pair to eventually get married. Both families disapproved of their union, but this did not deter the spouses, who reportedly enjoyed traveling and hiking together, with Musa spending a majority of his money on luxury goods. 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. If they determined that the occupant was alone or elderly, they would then break in, accost and proceed to kill them in a variety of ways including stabbing, beating the victims with chairs and slitting their throats. When finished, Musa and Ibrahim would burgle the residence, stealing money, jewellery and collectible items such as videotapes and cassettes, before fleeing the crime scene. Murders On January 5, 1994, Musa stalked 40-year-old Suad Farid until she went to her home in the Al-Rashid suburb. After memorizing the address,
