Aset Magomadova walks past media outside the Calgary courthouse on Oct. 7 before a judge convicted her of manslaughter. (Doug Hanley/CBC)A Calgary mother who strangled her 14-year-old daughter to death won't be sentenced until she undergoes a new round of psychological tests, a judge decided Wednesday.

Alberta Court of Queen's Bench Justice Sal LoVecchio adjourned sentencing arguments after Crown and defence lawyers said they are not satisfied with an earlier mental health assessment of Aset Magomadova.

In October 2009, Magomadova was convicted of manslaughter for the 2007 strangulation of her troubled daughter, Aminat, after a violent confrontation in their southeast Calgary home.

But the mother was acquitted of the original charge of second-degree murder.

The judge agreed Wednesday to order a new set of longer, more detailed psychological exams before he hands down his sentence.

An earlier psychological report concluded that Magomadova is at low risk of re-offending.

But defence lawyer Alain Hepner and Crown prosecutor Mac Vomberg told the judge not enough information was given about how that conclusion was reached.

"It'll be important to have standardized assessments," said Vomberg. "If there's any issues of depression or social adjustment or non-adjustment — things that can affect the court in determining the character of the person who is to be sentenced."

Magomadova will remain free until hearings resume in June.
