Your 'School Shooting of the Day'

Ho-hum, just another one.  This time at charter high school in North Philly area.  Two students, a guy and a girl, possibly both 15, shot in gym--or cafeteri--at close of day, rushed to hospital.  Reports suggest police still pursuing gunman, likely a student.  A Twitter report has a "suspect" stopped on a street nearby.   Police tweeted:  "SHOOTER - Turn yourself in. Get it over with now." UPDATE:  Police say shooter in custody, found near home, but gun missing. -- G.M.
