Police said they had one "person of interest" in custody and were looking for other suspects. The incident took place before 11 p.m. at the outdoor barbecue. An altercation broke out among some individuals and there was an exchange of gunfire. During that gunfire a number of innocent bystanders were struck," said Blair."It's a very shocking event, a lot of people were injured tonight." The two killed in the shooting were a teenage girl and a man in his 20s, officials said.

Those hurt in the incident suffered a mix of gunshot wounds and injuries from the mass panic that ensued.
