The first criminal trial related to the 2019 killing of Connecticut mother of five Jennifer Dulos is set to begin this week. Michelle Troconis is scheduled to go on trial Thursday on charges of conspiracy to commit murder, evidence tampering and hindering prosecution. Troconis denies the allegations. Police believe Dulos' estranged husband, Fotis Dulos, killed her in her New Canaan home amid bitter divorce and child custody proceedings. Her body has never been found.
