MONTREAL -- The man accused in Quebec's 2012 election-night shooting told a detective questioning him just hours later he couldn't remember anything about the events.

Richard Henry Bain returned to the stand at his first-degree murder trial Tuesday and insisted he still has no recollection of the night, telling jurors he only remembers a second round of questioning by investigators.

"I realized I was really in trouble on the Thursday (Sept. 6, 2012) at the second interrogation," Bain said, referring to two days after the election.

Bain has said his last memory before that interrogation is circling the Metropolis nightclub on the evening of the vote and having taken several pills earlier that day he says might have been anti-depressants.

The charges against Bain are connected to events outside the Metropolis nightclub later that night as Pauline Marois was inside giving her victory speech.

The charges include first-degree murder in the shooting death of lighting technician Denis Blanchette and attempted murder after the same bullet hit another stagehand, David Courage.

Bain has pleaded not guilty to all six charges, including three of attempted murder and two that are arson-related.

The Crown has alleged Bain approached the back of the club with a tactical assault rifle and fired a bullet and that the the acts were politically driven. On Monday, Bain denied any political motive.

Alan Guttman, Bain's lawyer, has told jurors he will argue his client is not criminally responsible due to a mental disorder.

On Tuesday, the jury began watching video recordings of the accused's police interrogation.

Bain said he doesn't remember the first attempt at questioning, where he seemed confused and complained of a headache.

Asked by a detective what murder and attempted murder charges mean to him, Bain mumbles, "I don't know."

Through much of the video, the accused keeps his head down, mumbling incoherently, ignoring a detective's questions or responding with grunts and groans until ambulance technicians arrive to check on him.

During the second round of questioning on the morning of Sept. 6, 2012, he appears more alert, answering investigators directly and saying the Lord's Prayer, adding "If I ever needed you, it's now."

He then wolfs down a breakfast sandwich and is later heard singing, "My God is Awesome" and humming the tune, "You Are My Sunshine."

Earlier on Tuesday, Bain recalled having what he called a "vision" of his mother, who died in 1997. The vision followed his consumption of pills outside the nightclub around 7 p.m.

"I saw my mother in front of me and she said: 'Richard what are they doing to us?'," Bain said.

He said he'd had visions of her a few other times, but never raised the issue with several psychiatrists following his arrest.
