(CNN) -- Jurors did not reach a verdict in their first day of deliberations Monday in the trial of Steven Hayes, the man accused of killing three members of a Connecticut family in a 2007 home invasion. 

They are expected to resume their work Tuesday morning. 

Hayes, 47, who has pleaded not guilty, is on trial in New Haven, Connecticut, for the murders of Jennifer Hawke-Petit and her two daughters. 

The killings took place in the New Haven suburb of Cheshire early July 23, 2007. The home of William Petit, his wife, Hawke-Petit, and two daughters was invaded in the middle of the night by Hayes and co-defendant Joshua Komisarjevsky, prosecutors say. 

Komisarjevsky will be tried separately. 

Judge Jon Blue gave instructions Monday morning and told the jury: "You are the sole judges of the facts." 

"We're in the home stretch," the judge said after going over all 17 counts with the jury. "No one will hurry you to produce a verdict." 

Their first duty will be to pick a foreman, and their verdict must be unanimous, the judge reminded the jurors. 

Soon after starting their deliberations, the jurors asked for a transcript of an interview by a state police detective, who spoke to Hayes soon after his arrest. The judge offered to have the testimony read back -- which the jurors declined. 

Later in the day, they sent a note to the judge asking for a definition of what constitutes starting a fire.Their deliberations Monday ran just over 2 hours.
