Lost Item No.: 1069142 - John F Kennedy International Airport, New York, US

I had my jewelry, black travel bag, brush and makeup in s small black backpack at terminal 4 gate 38. When I went back to get it several passenger eye witnesses told me the cleaning person from the airport took it. I checked with the cleaning supervisor and had 2 Delta airline supervisors trying to locate the person who was cleaning and he already left for the night. Surely you can figure out who was cleaning in this area at 9 pm on July 5th. I would like the items returned and will pay a $200 reward if returned. The jewelry has sentimental value and consisted of ratings, necklaces, string of pearls in a black and while zippered case
