Christopher L. Schenck, 22, of Williamsport, was denied bail Monday due to a history of crime and non-compliance with mental health treatment.
"Unless I'm convinced you're stable from a mental health standpoint, I'm not releasing you," Judge Marc F. Lovecchio told Schenck.
Schenck is charged with aggravated assault and endangering the welfare of a child after allegedly striking his girlfriend's 3-year-old son on April 22. The boy's injuries included bruising, internal bleeding and brain swelling, according to reports.
Schenck said he suffers from bipolar disorder and schizophrenia and has not received psychiatric medication since being committed to Lycoming County Prison on June 3.
"Psychiatrists at the prison tell me they're backed up. I tried going to the ER to get a prescription but they said no," Schenck said.
According to Lovecchio, Schenck has a history of refusing psychiatric treatment. While under supervision for a parole violation, Schenck failed to appear for five court-mandated psychiatric appointments between January and June.
"You can't blow off five appointments and complain you can't see anyone quickly enough. If you were out on bail before and didn't go to your treatment, what's different now?" Lovecchio asked Schenck.
Schenck was convicted of burglary in 2009. While under supervision, he committed two additional crimes - theft and forgery. He still was on supervision when he allegedly assaulted the young boy.
"I'm not trying to justify anything but all three times I wasn't on my medication that I needed," Schenck said.
Lovecchio denied Schenck's bail, citing the "very, very serious" nature of the offense.
"We're talking about the aggravated assault of a 3-year-old child. Given that you were the sole caretaker, the likelihood of your conviction is more probable than not," Lovecchio said.
Before his previous bail was vacated and modification request denied on Monday, Schenck had been held on a $1 million bond.
If convicted, Schenck faces a minimum of 4 1/2 years in state prison.
