John Jonchuck, who was found guilty of first-degree murder for dropping his 5-year-old daughter off a bridge four years ago, is asking for a new trial.
Jonchuck was sentenced to life in prison earlier this month, despite arguments from his attorneys that he was legally insane. No one disputed the 29-year-old Jonchuck dropped his daughter Phoebe 62 feet into Tampa Bay in January 2015, and that he had a long history of mental problems.
Prosecutors argued that Jonchuck was driven by vengeance and planned to kill his daughter to keep her away from her mother and grandmother.
The Tampa Bay Times reports the motion that was filed Friday argues several decisions made by the trial judge were improper or unfair to Jonchuck.
