She reported that she had been going through his candy bag and found the small plastic baggie that appeared to contain marijuana. She brought the baggie to the Nampa Police Department and turned it over to officers.Nampa Police officers field tested the substance found in the candy bag and it tested presumptively positive for marijuana. Officers obtained the route that they took while out trick-or-treating which was in the Sterling Meadows Subdivision off Lone Star Road between North Middleton Road and Midland Boulevard. They had been to several houses in that area and it is unknown which house provided the marijuana to the trick-or-treater.The baggie that contained the marijuana will be sent to the lab for fingerprint testing. This incident is still under investigation.The Nampa Police Department would like to remind parents to inspect all candy and items obtained by their kids while out on Halloween. If any candy looks like it has been tampered with or opened, it is best just to throw the item away.
