It says the prosecutor alleges Kasian was tortured and mutilated before she was slain and that the blood was drained from her body.
Blake Leibel, son of Lorne Leibel, the founder of Toronto-based real estate company Canada Homes Inc., has been arrested in connection to the death of his live-in girlfriend in Los Angeles after her body was found in the couple's apartment last week.
Blake Leibel, 35, a graphic novelist and screenwriter, could face the death penalty if convicted of first-degree murder in the slaying of his 30-year-old girlfriend, Iana Kasian, prosecutors said.
Kasian was tortured and mutilated before she was killed, and all of the blood was drained from her body, according to Deputy District Attorney Tannaz Mokayef. Leibel is the son of an affluent Toronto real estate developer known for his collection of Ferraris.
Leibel was arrested at the scene.
In 2011 Leibel's mother, Eleanor died of brain cancer.
Police officers arrested Leibel at his apartment on May 26 where they found him barricaded with Kasian's body. He was booked May 20 and released later in the day on $100,000 bail, according to jail records.
US authorities have said Kasian's mother had reported her missing.
A decision has yet to be made whether prosecutors will seek the death penalty in this case.
The same database says Leibel was charged with another felony six days earlier, and released with a court date scheduled for June 17.
A local television station, KTLA 5, reported the couple's child was safe and being cared for by a family friend.
However, court documents related to his mother's will reveal Leibel's life in L.A. was financially supported by both his parents.
Lawyer Alaleh Kamran questioned Leibel's mental competence, prompting Los Angeles Superior Court Judge Keith Schwartz to a psychological evaluation, according to the Post.
