(07-05) 17:33 PDT SAN FRANCISCO -- The 16-year-old drummer of a San Francisco punk rock band was seriously injured Wednesday night when fireworks thrown by someone at Dolores Park exploded near her right hand, police said.
It occurred shortly before 10 p.m. as Roisin Isner, who has played drums with the band Tinkture since 2004, and an unidentified girl watched San Francisco's fireworks display from a hill in Dolores Park in the city's Mission District.
"They were just sitting there chatting, then they saw a bright flash between them and the girl started screaming," said San Francisco police Sgt. Steve Mannina.
Police began canvassing the park for witnesses as paramedics tended to Roisin's hand and transported her to San Francisco General Hospital, but investigators didn't find much in the way of witnesses or evidence, Mannina said.
"We don't have a whole lot," he said. "We're definitely looking for more witnesses."
Mannina said police have not determined, and probably cannot determine, just what was thrown at Roisin and the other girl, who was not injured. Tinkture is an all-girl three-piece punk band that was founded in 2002. Roisin didn't know how to play the drums when she joined the band in 2004 after the founding drummer was dumped, according to the band's Web site. The band has performed at some of the area's most well known clubs, including Slims, Bottom of the Hill and 924 Gilman.
