HOUSTON – A two-hour special edition of "Dateline NBC" on Friday featured the case of a father from the Houston area who was sentenced to death after killing his daughter's husband and his daughter's best friend.
It's a case KPRC 2 Investigates has been tracking for a half-decade.
Prosecutors described the crimes committed by 60-year-old conservative Muslin Ali Irsan as an honor killing and a family affair.
Irsan became enraged, prosecutors said, after his daughter, Nesreen Irsan, married Coty Beavers, a 28-year-old Christian, and then converted to Christianity.
Investigators said the best friend of Nesreen, Gelareh Bagherzadeh, had introduced her to Beavers.
Ali Irsan, his son, his wife and one of his daughters, Shmou Alrawabdeh, 40, were all arrested in connection with the plot. Alrawabdeh testified against Ali Irsan. In exchange for her testimony, she pleaded guilty to aggravated kidnapping and was sentenced to time served.
Josh Mankiewicz interviewed Ali Irsan from behind bars.
Interview: Ali Irsan from behind bars
Irsan: And the law enforcement and the government and the United States -- they bullied, blackmailed and intimidated every person that put me here.
Mankiewicz: You think everybody who--
Mankiewicz: (blank) testified against you did so because they were intimidated?
Irsan: Three of them, that were the main thing. They were intimidated, yes.
Mankiewicz: So your wife, your nephew, your daughter, who all testified against you, you think that only happened because they were intimidated?
Irsan: Yes. They were forced. If-- if you don't do it, we're gonna get you. (SIGH)
Mankiewicz: And you think this is Islam on trial, not--
Irsan: Yes. It is Islam, because my daughter claimed to them that because she turned Christian that I'm gonna come after her.
Mankiewicz: Nesreen wanted you to leave her alone. And if you had left her alone, you probably wouldn't be in here.
Irsan: If the police did not use the KGB tactic, I would not be here.
Status of other cases
