Three years after Spring Phillips was found dead in her downtown Toronto apartment, a man has been found guilty of her murder.

Levi Aggek pleaded guilty to one charge of second-degree murder and was sentenced to life in prison with no chance of parole for 20 years in a Toronto courtroom Monday morning.

CTV's Tamara Cherry says the court heard that Aggek had consumed alcohol and marijuana the night he sexually assaulted Phillips and beat her to death on Dec. 5, 2009.

It was shortly after midnight on that Saturday morning when police were called to Phillips' high-rise apartment building near Wellesley East and Sherbourne Streets.

When police arrived, they found the 26-year-old Phillips suffering from obvious signs of trauma. The mother of one was pronounced dead at the scene.

Aggek, new to Toronto and homeless at the time, was known to have been sleeping on Phillips' couch that night.

He was seen, on the apartment's security camera footage, leaving the building via the elevator at approximately 5 a.m.

A vigil was held outside Phillips' building that night. An hour later, Aggek was arrested.
