(AP Photo/Multnomah County Sheriff’s Office) (Newser) – A "person of interest" arrested after a school shooting yesterday in Portland, Oregon, has ties to gangs, police say. Authorities haven't said whether Lonzo Murphy, 22, was the gunman in the attack, which left three hospitalized, the AP reports. Two of those hurt are also linked to gangs, police note. Officials are still seeking two other people in the Rosemary Anderson High School shooting, they say. Murphy has been detained without bail after violating parole following a robbery conviction, the Oregonian reports.
