A man facing trial for allegedly allowing his 6-year-old daughter's teeth to rot and who is under investigation in the deaths of several of his other children was charged Thursday with lying under oath about attending drug rehab.

At a hearing Dec. 9 in Northampton County Court, Kenneth A. Wanamaker Jr. committed perjury by saying he had enrolled in an inpatient treatment program in Lebanon County, authorities said. The facility had no record of him as a patient and Wanamaker could supply no proof.

Wanamaker continued to insist under oath he had been in treatment as Judge F.P. Kimberly McFadden ordered him to forfeit $25,000 in cash he posted for bail. Wanamaker, 37, of Lehigh Township, avoided jail in November by promising a judge he'd check himself into rehab.

At the hearing, Wanamaker pleaded with McFadden, saying he and his domestic partner, Jessica L. Hoffman, had a newborn baby to care for, but McFadden said Wanamaker had misrepresented himself to her and repeatedly flouted court orders.

Wanamaker and Hoffman, 32, face child endangerment charges that they allowed their daughter's teeth to decay so severely that a dentist said it could have killed her. They are scheduled to again go before McFadden on Friday for a pretrial conference.

District Attorney John Morganelli said prosecutors are investigating the couple further, given that a baby son died of pneumonia in 2011 and there have been two stillborn deliveries since 2007 — one linked by a coroner to Hoffman's methamphetamine abuse.

Wanamaker, who remains in county prison under $100,000 bail, had not yet been arraigned on the perjury charge as of Thursday afternoon.

According to court records in the perjury case:

County pretrial services officer Nina Reynard told a county detective that Wanamaker failed to comply with his bail conditions by not attending drug rehab.

In a conversation with Wanamaker on Dec. 5, Reynard said "he swore he was at the facility and everyone else had the wrong information." Wanamaker said his credit card was declined and he paid cash at the inpatient facility.

The records for the inpatient facility, White Deer Run, state that on Nov. 21, Wanamaker appeared at the Lebanon facility and completed some paperwork, but was documented as "refused."
