Ali Asghar Borujerdi was born in 1893 in a city called Borujerd, Iran. He grew up in a family with a long history of criminal activities. Asghar had two brothers named Reza and Taghi, and one sister. His grandfather, Zulfali, was known as a bandit who robbed caravans traveling through Borujerd, Malayer, and Arak. Sometimes, he even killed the owners of these caravans.

Asghar's father, Ali Mirza, was also recognized for his violent behavior. He was reported to have killed more than 40 civilians with his bare hands. Due to his notorious actions, Ali Mirza moved his family to Baghdad, Iraq, seeking safety. During their journey to Mashhad, he was killed by the Persian Cossack Brigade. Asghar's mother and siblings continued on to Baghdad after his death.

Asghar was told stories by his mother about his father being a soldier who died during military service. After arriving in Baghdad, the family initially traveled there to perform a pilgrimage in Karbala. Eventually, they chose to settle in Baghdad instead.

Ali Asghar Borujerdi, known as "Asghar the Murderer," committed many crimes in two countries: Iraq and Iran. His first murders took place when he was in Iraq. After being released from prison for abusing children, he began to kill. He confessed to killing 25 children and adolescents in Baghdad. He often drowned his victims. To hide his actions, he would sometimes shoot those who resisted. After these murders, he fled to Iran.

Once in Iran, Asghar settled in Tehran. There, he killed eight more boys, all adolescents. The bodies were found in various places, including furnaces and aqueducts. This caused fear among the people in Tehran.

In January 1933, police discovered a body in a village south of Tehran. This led to the finding of two more bodies in the area. As the police investigated, they found more remains, including the skull of another young man in February. The police worked hard to catch the killer, fearing for the safety of children in the city.

On March 10, 1933, police arrested Asghar. During their investigation, they found bloody clothes and a knife in his possession. His neighbors informed the police that he had introduced the murdered boys as his siblings.

After several interrogations, Asghar admitted to the murders. He was charged with the rape and murder of multiple children. His trial began in June 1934, and he was sentenced to nine years in prison followed by execution. This sentence was confirmed by the Supreme Court of Iran.

Asghar was executed on July 6, 1934. Initially, he seemed calm, but became fearful when confronted with his death.
