The decision came Monday following a preliminary hearing for Joy O'Shea-Woomer, who's charged with homicide and felony drug offenses.
She had been caring for Brent Weaver, who had cerebral palsy, when he died in September 2002.
Brent's mother Carol Weaver testified that the family didn't keep morphine in the house and that the family had previously learned that the boy was allergic to the drug.
A county detective testified that the 49-year-old O'Shea-Woomer told him she hadn't been feeling well that night and didn't want to be there working.
O'Shea-Woomer's lawyer argued there isn't evidence linking her to the death.
