(Algerina Perna/The Baltimore Sun via AP) (Newser) – To cheers from local residents, Baltimore State's Attorney Marilyn Mosby announced today there was no probable cause for Freddie Gray's arrest and that six police officers will be charged in connection with the 25-year-old's death, NBC News reports. The stiffest charge—second-degree murder—will be filed against the driver of the police van. Other officers face charges of involuntary manslaughter, assault, and illegal arrest, reports the AP. In a press conference held today, Mosby also said that the knife Gray had clipped inside his pants pocket was not the switchblade officers alleged it was, but a legal knife—meaning there was no justifiable cause for his arrest, per the AP. Gray's autopsy report was passed over from the medical examiner to Mosby's office this morning, while the Baltimore police commissioner noted yesterday that his department had sent its own "confidential" info on Gray's death to Mosby, NBC reports. Mosby said she came to her conclusion that charges should be filed based on the medical examiner's homicide determination and info culled from her own investigation into the matter, CNN reports. "We're not just relying solely on what we were given by the police department," she said, per NBC. In the meantime, Mosby is urging for calm in the tense city. "I heard your call for 'no justice, no peace,'" she said at the press conference, per ABC News. "However your peace is sincerely needed as I work to deliver justice on behalf of Freddie Gray." The Justice Department is also conducting its own investigation.
