(CNN) -- Closing arguments were made Friday in the trial of Steven Hayes, the man accused of killing three members of a Connecticut family in a 2007 home invasion. 

Jurors are expected to begin deliberations as early as midday Monday. 

Hayes, 47, who has entered a plea of not guilty, is currently 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 in the early hours of July 23, 2007. The home of Dr. William Petit, his wife Jennifer 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. 

Prosecutor Michael Dearington laid out an elaborate timeline of events, fully implicating both Hayes and Komisarjevsky in the gruesome killings. 

"We've reached the point where very shortly this case will be in your hands," he told jurors. "I doubt you could have comprehended how horrendous this evidence would be." 

Earlier in the week, a trial witness -- a Connecticut prison officer -- testified that he overheard Hayes confess to another inmate that he killed Hawke-Petit. Hayes also reportedly wondered out loud whether Petit might have been in cahoots with his co-defendant, Komisarjevsky, because Petit had been able to escape. 

Hayes said he had tied the father in the basement of the home himself, and that he doubted he could have gotten loose without help from Komisarjevsky, the witness -- Jeremiah Krob -- testified.
