I Lead Ramp Service Man D was the Lead working flight out of ZZZ. I was on the right side of the 767 aircraft loading cargo. While loading; I noticed a shipment of dangerous goods on the orange gate cart along with some other miscellaneous items all planned to go out on [the] flight. Due to a live animal that was scheduled to travel; the dangerous goods dry ice of 33 pounds appeared on the DSTG as a hold off item below the weight restricted line. Mentally; I thought to myself that I would come back and get the shipment of dry ice later after the flight was gone; and have someone from the cargo area come and pick the shipment up and take it back to the cargo building. I also had a bag match crew at the gate that was assigned to help assist with containerizing the bags for the flight; and also assist with the bulk pit. There was a pet safe runner that arrived at the gate to drop off the live animal to have put in the bulk pit. I scanned the bar code tag that was on the kennel which was good to go. At this time it's about 10-minutes before the scheduled departure time. From the time that I went inside the kiosk at the gate to double check on unimatic that all the correctly planned cargo for the flight was on board that I input from the scanner; somehow the hold off item got loaded accidentally without me knowing. At that time the aircraft was being dispatched back from the gate; that's when I went back outside to check the orange gate cart to see if the hold off item of dry ice was still on the cart; and it was gone. That led me to believe that the dangerous goods and the live animal was loaded together in the same cargo compartment. I immediately called the area supervisor on the radio and notified her of the error that was made as the aircraft taxied away from the gate. The supervisor made a couple of phone calls from inside the kiosk. I know one of the calls was to cargo personnel; and they both came up with the conclusion that the shipment of dry ice was still down in the cargo building. That raised another red flag in my head; because the only sure way that the shipment would have made it back to the cargo building so quickly would have been by a cargo runner in a van. Possible; but not likely. After the aircraft took off and was airborne; the area supervisor received a phone call back from cargo to confirm that the shipment of dry ice was not there at the cargo building as originally said. The flight was diverted to ZZZ1 where the shipment of dry ice was removed from the aircraft.
Central Load Planning (CLP) held off item 022 (HAZMAT-DRI ICE) for LIV in bulk pit. Station called CLP stating that HAZMAT item nowhere to locate and Lead Ramp service employee confirmed item was loaded into bulk pit with the LIV after flight 54 minutes in to air. Decision made to divert flight to ZZZ1. Result- animal was still alive and removed sent it to veterinary for checkup. Flight re-departed after re-fueled and catered.
Ramp Agent and Central Load Planner reported communications breakdown with load personnel regarding HAZMAT and live animal cargo location.
