Alexander Pryce is a character in DEXTER.
He was a graduate student adored by his family and friends that met with an unfortunate hit-and-run accident where he was killed on impact. The man responsible, Matt Chambers, was held accountable due to his vehicle being used on the scene but was able to secure himself from being convicted for the crime despite his history of manslaughter under different assumed names. After Dexter Morgan sat in on the hearing for Chambers and observed Mr. Pryce's mourning of his son, he secured enough evidence to put Chambers on his table and even showed the family video from Alexander's birthday party in place of his usual photographs of their victims. Chambers was then stabbed in the heart and disposed of as normal, with hopefully some peace coming to the Pryce family in his disappearance.
