Jury deliberations resume Tuesday in Washington County in the re-trial of Matthew Slocum.
During closing arguments on Monday, Slocum's attorney, Mike Mercure, again maintained that his client's girlfriend, Loretta Colegrove was the murderer.
Forensic tests showed Lisa Harrington's blood on Colegrove's shirt, and on one of the guns recovered.
Special Prosecutor Eric Galarneau pleaded with jurors to hold Slocum responsible, arguing that doesn't prove she was the killer, and told the jury they should hold Slocum responsible for the murders.
Slocum was convicted for the deaths of his mother, stepfather, and stepbrother in 2011, but that verdict was overturned on appeal.
