Police say a detective saw Jonchuck throw his daughter Phoebe off of the Dick Misener Bridge in the middle of the night in January 2015.
Jonchuck has a history of mental health issues.
On multiple occasions, a judge has ruled him unfit to stand trial, but in March of 2017 ruled him competent to stand trial.
Bruce Bartlett with the State Attorney's Office told ABC Action News the reason why they took the death penalty off the table was to better focus on the sanity issue. This saves time and expenses and dispenses with many of the pretrial motions and allows the state to focus on the main issue — his sanity. The trial date remains the same — September 24, 2018.
