elderly woman thrown in pool

Anyway from what I could read/tell this elderly woman who was walking her two dogs (and had them attached to her) was trying to get over to her friends party when she came across this group of teens(?) by the public pool with blaringly obnoxious music. As she walked she asked them to please turn it down and also looked as though she was waving her hands so they would see/hear her to get out of the way so she could pass. One of the teens started screaming for someone to throw her in the pool. Another teen picked her up and fell and she and her dogs and the teen hit hard. The woman and dogs looked horrified as the teen AGAIN picks her up by her shirt and leg and throws her and her dogs into the pool!
