A huge Saturday night house party broken up by police in a North Jacksonville subdivision ended with one man shot in the leg as he and hundreds of other party goers fled the officers arrival. But the party didn't stop at the home in the 12000 block of Sampson Road, according to the Sheriff's Office. About 300 teenage partyers ignited a flash mob about 90 minutes later at the Walmart Supercenter at 12100 Lem Turner Road. Watch the video!
