The killer is not Maggie. The killer is a man. The psychic's warning to Abby was "He wants you dead! He will not stop!."
The TV Guide spoiler that Henry will be found covered with the blood of a loved one hasn't happened yet. I expect that either JD or Trish is killed in one of the next 2 episodes. The critics were given the first 9 episodes to preview.
At one time Wikipedia had 'Fwoopt' as the title for episode 8. Perhaps the scene where Cole Harkin gets shot with an arrow (and dies?) happens in the next episode.
