Just passing along the latest news on Roisin Isner, the 17-year-old drummer hit by a firecracker in Dolores Park on July 4.

The 17-year-old boy the SFPD arrested has been released by the juvenile court to home detention, but remains a person of interest in the case. They have videotape footage confirming that he was on the scene, and he admitted to anarchist activity and to throwing firecrackers in the park and in a phone booth earlier, but said he didn't throw anything at people.

Isner, for what it's worth, says she knows the guy they arrested, and he's not the person who threw the firecracker at her, saying "he's an artist, of course he's an anarchist." She also noted that witnesses have said the guy who actually did throw the firecracker at her was a husky 20-something guy (and riding a fixie, for what it's worth).

Isner's right index finger was amputated, and she has more surgeries scheduled on her hand, but she says she should be okay and her middle finger should be able to operate normally and take over her index finger's functions. The proceeds from Monday's Punk Rock Sideshow benefit concert will go to pay for her doctors, because her family doesn't have health insurance. When's Ammiano and Newsom's universal health care coverage go into effect? (Note: kids already get health insurance from the city at certain qualifying income levels -- not sure if that information'll help the Isners, but there it is if you the reader might want to look into it.)
