A court heard the final arguments Friday in the trial of a man who violently attacked a gas station attendant in Dartmouth, N.S., in 2007.

Michael Derrick Robicheau has admitted to attacking the woman.

In an agreed statement of facts presented in court in October 2010, Robicheau admitted to assaulting the woman on Aug. 21, 2007, cutting off her clothes, sexually assaulting her and slashing her throat.

Robicheau pleaded not guilty to attempted murder, sexual assault, unlawful confinement, robbery and possession of a weapon on the grounds that he was not criminally responsible for his actions.

The woman was working the night shift alone at an Ultramar station in Dartmouth when she was attacked. She called 911, but was unconscious by the time help arrived.

Robicheau was arrested shortly after in some nearby bushes. He had been released from prison 10 days earlier after serving two-thirds of a sentence for numerous convictions. He has a long criminal history, including a conviction for attacking a clerk in a sandwich shop.

Question of responsibility

The only question for the court is whether he can be found criminally responsible.

Four psychologists have testified that Robicheau has schizophrenia, but offered differing opinions on if he knew that what he did was wrong and that he must face consequences for his actions.

Throughout the final day of his trial, Robicheau sat quietly, often with his eyes closed. His victim, who still bears physical and psychological wounds from the late-night attack, was also in court. She stared at her assailant throughout the hearing.  

The court will deliver its verdict on June 3.
