Suspect in killings was arrested, released on firearm charges weeks ago By Megan Cassidy San Francisco police are asking for the public’s assistance in locating a murder suspect they have linked to two deadly shootings that occurred just hours apart Saturday in the Potrero Hill neighborhood. Officials said they have three warrants — two for murder and one for attempted murder — for 32-year-old San Francisco resident Robert Newt, who they described as “armed and extremely dangerous.” Investigators said he is known to frequent the Bayview-Hunters Point area and they warned the public not to approach Newt if he is spotted, but to note his location, clothing and vehicle description and immediately call 911.
