Motive: Deception

SINOPSE

The killer: Diane Torrance, a construction site flagger. The victim: Dr. Stan Matthews, a senior coroner, and Betty's mentor. As such, news of his death hits her particularly hard. His dead body was discovered on an upper level of a downtown parking lot, he having died from several abdominal wounds made by what looks to be an ice pick. He, at the time, was testifying as an expert at a child death case, in which the four-year-old victim seems to have been shot accidentally at a meth house party by drug dealer Brad Hitchens. Betty is taking over as the expert for that case. Despite the surveillance video from the parking lot not showing any direct tie to any individual as the murderer, the Homicide detectives are able to ascertain that a car speeding out of the parking lot at the time belonged to Daniel Hitchens, Brad Hitchens' disgruntled brother, who had had run-ins with Stan before. But Angie is also able to determine from the surveillance footage that the killing was premeditated. Other evidence they find at the parking lot leads them to a construction site for information for the killer. But it isn't until Betty digs deeper into the evidence for the trial and Stan's own past in relation to that trial that they may have a motive.
