John Jonchuck's motion for a new trial has been denied.
The man convicted of first degree murder earlier this year for throwing his daughter off a bridge in 2015 was asking for a new trial.
He was found guilty and sentenced to life in prison.
His attorneys claim the prosecutor committed misconduct by making certain statements in the opening arguments and then offering no evidence in support of those statements, thus resulting in substantial rights of Jonchuck being prejudiced.
They also claim the court admitted evidence of Jonchuck's bad character or prior bad acts they say should not have been admitted.
There are nine other reasons for a new trial that the defense pitched in its motion, all claiming that the errors made by the trial court denied Jonchuck the right to a fair trial.
A judge in Pinellas County addressed the defense's concerns and determined the motion for a new trial was without merit and denied it.
