Is this self defence or another honor killing ?

CALGARY - A mother accused of   strangling her teenage daughter  with a scarf was acting in self defence, her lawyer said Monday. Mark Tyndale, who represents Aset Magomadova, pointed to a statement of agreed facts entered in the second-degree murder trial. He said 14-year-old Aminat Magomadova, who died Feb. 26, 2007, had been "habitually running away from home, boasting that she was using drugs, being sexually active and stealing" --behaviour that caused stress for the rest of the Muslim family.

.....According to the agreed facts, Aset made phone calls to Austria and did not call 911 for about an hour after Aminat's death.
