PHILADELPHIA — A fundamentalist Christian couple who relied on prayer, not medicine, to cure their dying toddler son was convicted Friday of involuntary manslaughter and child endangerment.

Herbert and Catherine Schaible of Philadelphia face more than a decade in prison for the January 2009 pneumonia death of 2-year-old Kent.

“We were careful to make sure we didn’t have their religion on trial but were holding them responsible for their conduct,” jury foreman Vince Bertolini, 49, told The Associated Press. “At the least, they were guilty of gross negligence, and (therefore) of involuntary manslaughter.”

The Schaibles, who have six other children, declined to comment as they left the courthouse to await sentencing Feb. 2.

Experts say about a dozen U.S. children die in faith-healing cases each year. An Oregon couple were sentenced this year to 16 months in prison for negligent homicide in the death of their teenage son, who had an undiagnosed urinary blockage.

Assistant District Attorney Joanne Pescatore will ask the judge at sentencing to put the couple’s other children under a doctor’s care. She was not yet sure if she would seek prison terms for the two felonies.
