On 10 June 1998, twelve people were killed in a mass shooting in Amman, Jordan. Eleven of the dead were members of the Qashash family. A relative, 19-year-old Saeed al-Qashash (; also spelled Sa'id al-Qashash), was arrested two days later for the murders, confessing that he had committed the crime to avoid pressure over his academic performance. He was found guilty of murder and executed in 1999.

The murders caused widespread shock in Jordan, which has nationally low crime rates. It was the deadliest familicide in modern Jordanian history.

Murders On 10 June 1998, between 12:00 a.m. and 2:00 a.m., Saeed al-Qashash killed his parents, six siblings (aged 10 to 30), a brother-in-law, a nephew, a niece, and a classmate at the Qashash family home in the Abu Alanda area southeast of Amman. Five of the victims were children and all of them were shot in the back of the head. Investigators first assumed that Qashash had lured each victim into the basement to be killed shortly after they arrived at the residence, though he later stated that he first murdered his mother Thuria as she was working in the kitchen. The final victim was Atta Shalan, a close friend of Qashash.

Afterwards, Qashash called his the workplace of his father Amin, telling them that he would be unable to attend his shift as a school bus driver due to illness. He then piled up the bodies and covered them in blankets and carpet. He then used his brother-in-law's car to drive to the market to buy bricks and cement, which he used to wall-in the bodies into the basement. At 14:00, Qashash informed another relative of the murders, claiming he had spent the night at a friend's house studying and discovered the crime scene upon returning in the morning. Qashash and the relative then informed police. Qashash was found suspicious as the sole surviving member of his family and arrested two days later, confessing to the murders in police custody.

Motive Qashash had failed his last year of high school in 1997 and recently completed the first of two Tawjihi repeat exams. His father had repeatedly threatened to throw Qashash out of the house in case of failure. The Associated Press reported that the other family members and his friend Atta Shalan had "all harassed him about his failures in school". Qashash had stolen his father's 7 mm pistol the week prior to the attack and bought 25 bullets in preparation for the murders.

Trial and execution On 30 November 1998, Qashash was convicted of 12 counts of premeditated murder following a one-day trial. He pleaded with Judge Mohammed Ajamieh to spare his life, but was sentenced to death. Qashash did not react to the sentence.

Qashash's death sentence was opposed by Amnesty International, which urged Crown Prince Hassan bin Talal to commute the sentence.

Qashash was executed by hanging on 6 June 1999 at , about 60 miles south of Amman. In his last statement, made minutes before the execution, Qashash asked for forgiveness and apologised for the murders. He was formally declared dead at 6:00 a.m. on 7 June. His body was not accepted by other relatives, who asked government authorities to handle the burial.
