Man reportedly from Toronto faces torture and murder charges in L.A.

LOS ANGELES — Torture and murder charges have been laid in Los Angeles against a man reportedly from Toronto.

The Los Angeles County District Attorney's Office says in a release that Blake Leibel, who reports say is the son of a Toronto-area businessman, has pleaded not guilty to the charges in the death of his live-in girlfriend.

The release says Leibel is accused of killing 30-year-old Iana Kasian, on or between May 23 and 26.

It says the prosecutor alleges Kasian was tortured and mutilated before she was slain and that the blood was drained from her body.

Police say that Kasian was reported missing, and when they searched the home that she shared with Leibel, they found her body in the bedroom with what looked like blunt force trauma to her head.

The district attorney's office says Leibel faces a total of four charges: murder, mayhem, aggravated mayhem and torture. Prosecutors say he pleaded not guilty to all of the charges in a Los Angeles court on Tuesday.

According to the release from the district attorney's office, Leibel -- if found guilty -- could face the death penalty or life in prison without the possibility of parole, but prosecutors haven't announced whether they'll be seeking the death penalty. The allegations against Leibel have not been proven.

The National Post has reported that Leibel is the son of Toronto-area businessman Lorne Leibel, the owner of Touchstone Homes.

Representatives from Touchstone Homes and Global Affairs have declined to confirm the relationship between the suspect and the elder Leibel. The younger Leibel's lawyer didn't respond when contacted by phone and email.
