SAINT-JEROME, Que. -- The jurors at Guy Turcotte's murder trial completed their second day of deliberations on Tuesday without reaching a verdict.

They did ask the judge at one point for copies of two articles of the Criminal Code -- one that defines the notion of not criminally responsible by way of mental disorder and another that deals with sentences for murder convictions.

Quebec Superior Court Justice Andre Vincent granted their first request but not the murder-related one because sentences do not fall under a jury's authority.

Turcotte is charged with first-degree murder in the 2009 slayings of his children Olivier, 5, and Anne-Sophie, 3.

The jurors began their deliberations Monday afternoon and can reach one of four possible verdicts: not criminally responsible by way of mental disorder or guilty of first-degree murder, second-degree murder or manslaughter.

Turcotte, 43, admitted to causing the deaths but his lawyer argued the jury should find him not criminally responsible by way of mental disorder.
