Cold As Ice

Dr. Carla Dalton (Laura Niemi) is killed in the parking garage near a boys' hockey game. The weapon used is identified as a skate hook for tightening laces, and Carla's car is found dumped in the river. She was in Boston trying to track down her nephew Todd, who had Huntington's disease. Carla's brother-in-law Michael Leahy (David Barry Gray) killed his wife when Todd was a toddler, took his son, and changed their identities. He also killed a suspicious Carla when she came to the game to look for Todd. Meanwhile, Cailin shows up at Maura's, asking to stay with her while Hope is out of town, even though a sitter was left in charge. Maura views Cailin as a child and becomes concerned about her behavior, but Jane tells her to act like Cailin's big sister instead.
