In April 2015, Silvonek, who has been held in the Lehigh County Jail, was charged as an adult in the death of her mother, a 54-year-old Jim Thorpe native whose body was found in South Whitehall Township.

Silvonek's boyfriend, Caleb Gregory Barnes, 21, was charged with homicide, abuse of a

corpse, tampering with physical evidence and criminal conspiracy. Barnes' case is scheduled for trial on April 11.
