The deadbeat Arizona dad who admitted to leaving his 2-year-old daughter to die in a sweltering car while he watched porn is dead — with his cowardly ending deemed a suicide, according to reports. Christopher Scholtes, 38, was found dead in a Phoenix home just after 5 a.m. Wednesday, police told The Post, the same day he was due to report to prison ahead of his sentencing, where he faced up to 30 years behind bars. “Instead of coming in to take account for what has occurred here, we have been informed, and we have confirmed, that the father took his own life last night,” Pima County Attorney Laura Conover said in a statement Wednesday.
