The case against Vanessa took longer than expected, more than one year had passed before they won the case against her. Henry's team filed a case against Dimitri being the mastermind for the explosion, Amy's kidnapping, and the plane crash even though Vanessa told him that she had dealt with him already. Henry wanted to make sure that there was no more threat to their lives when Vanessa received her sentence.
With the collective effort of Rei's team, Uncle Trev's connection in the military, and the police, they were able to prove that Dimitri was dead. His body was found under the basement concrete floor of the Turner mansion.
As much as Henry wanted to send Francis to jail too, he was acquitted for lacking evidence of his participation in his father and Vanessa's crimes. They couldn't get any witnesses to testify against him at all.
