New information into the mysterious death of a 10-year-old Omaha boy that occurred last April.

Police now say that the boy died from a powerful combination of prescription drugs.

Douglas County Attorney Don Kleine says an autopsy shows Shykell Robinson died from an overdose of four drugs — methadone, oxycodone, lorazepam and haloperidol.

Authorities haven’t figured out how the boy got the drugs. No arrests have been made in connection with the case.
