Hisamuddin Ibrahim, 21, was enraged when he found out that his married sister was having an affair. He then ordered the arson attack in October 2009 on the home of the offending man while he would be inside, sleeping.
According to Sky News
, Ibrahim's best friend Habib Iqbal, 25, took two of his friends along to 175 London Road, Blackburn, Lancashire, UK, where they proceeded to pour gasoline through the mail slot and then light the house on fire.
The wrong house was targeted, however, and the married couple, Abdullah Mohammed, 41, and his wife Aysha,39, along with a 14-year-old daughter and 9-year-old son were caught inside. The two children survived, but their parents later died in the hospital of smoke inhalation.
Preston Crown Court judge Mr Justice Henriques told the four men in court: "You have wreaked devastation on a blameless, devout family.
"They just happened to live at an address one digit removed from your intended target.
"It is a most cruel irony that two such devout members of the community, both deeply religious, should have lost their lives to such a perverted and wicked act."
Habib Iqbal was sentenced to a minimum of 25 years, while his two friends, Sadek Miah, 23, and Mohammed Miah,19, were sentenced to jail terms of no less than 21 years for Sadek and a minimum of 19 years for Mohammed in jail. Hisamuddin Ibrahim was sentenced to life in prison, with a minimum of 28 years for ordering the "honor killing."
Another son of the murdered couple said his sister and brother suffer from recurring nightmares, believing another attack will happen. They also had physical injuries, including burns on the daughter's body.
The judge believed evidence showed there may have been other people involved, besides the four convicted men, and he urged police to continue to investigate.
