Friends attended a funeral for Ashley Kline Wednesday night.
Adam Lynch, 21, of Reading, and Ryan Schannauer, 19, of Wyomissing, are charged with homicide, arson, abuse of corpse and other offenses in Kline's death.
Her burned remains were found January 12th in a remote location in Lancaster County.
Supporters have started a petition in Kline's name on the website change.org.
They want Pennsylvania to order stricter sentences for crimes against the mentally or physically impaired.
Her father says a case of lead poisoning when she was an infant left Kline, who was 23, with the mental capacity of a 15 year old.
