Paramedics knocked my brothers legos and I dont know where to place these missing pieces/ if im missing any.

Nearly a year ago or so my brother passed, and when the paramedics came into his room they knocked over his lego sets and some pieces flew off. Not sure where they go/ if any fell into the bags of the paramedics. I saw a video online of the antennas on the top of the building but theres no slot for them. I also cant find my brothers lego books. I dont know much about lego myself, so hopefully yall can help! I think the lego sets are ninjago gardens or ninjago city or something. submitted...
