问:去年12月12日,我家附近某超市举办“双十二低价风暴”活动,现场发放礼品并赠送现金券。当时现场聚集了很多人,大家哄抢礼品和现金券,现场秩序一片混乱,包括我母亲在内的好几个老年人被挤倒摔伤。事后,我母亲被送往医院治疗,经诊断为左胫腓骨粉碎性骨折,期间共花费医疗费5万余元。现在我母亲已经治疗终结,但由于我并不清楚是谁将我母亲挤倒的,所以不知向谁索赔,请问我该怎么办?徐树美答:首先,你必须弄清楚谁具有赔偿义务。我国《侵权责任法》第37条规 Q: On December 12 last year, a supermarket near my home held a “Double Twelve Low Price Storms” campaign, giving gifts and giving cash vouchers on site. At that time, a lot of people gathered at the scene and everyone looted gifts and cash vouchers. The scene was chaotic. Several elders, including my mother, were knocked down and fell. Afterwards, my mother was taken to the hospital for treatment and was diagnosed with comminuted left tibiofibular fractures during which she spent a total of more than 50,000 yuan on medical expenses. Now my mother has finished treatment, but since I do not know who pushed my mother down, I do not know who to claim for. What should I do?
