Veda Washington-Abusaleh, Sterling's aunt, was in tears after meeting with Landry.
Sterling, a 37-year-old black father of five, was shot six times by officer Blane Salamoni on 5 July 2016.
The Department of Justice said last spring that Salamoni put a gun to Stering's head when Sterling refused the officers' order to put his hands on the hood of a auto. One had been previously involved in the shooting of another black man two years prior that had led to administrative leave.
Attorneys for Sterling's relatives have said federal authorities told them Salamoni pointed a gun at Sterling's head and threatened to kill him before the struggle began. As a convicted felon, Sterling could not legally carry a gun. According to federal officials, as related by Sterling's family and attorney, he said: "I'm going to kill you, bitch".
Federal authorities said their ten-month investigation failed to uncover evidence that the officers "willfully" deprived Sterling of his civil rights.
"The seminal question presented is whether Officers Howie Lake and Blane Salamoni can be held criminally responsible for the death of Alton Sterling under applicable laws of the State of Louisiana".
The Attorney General released a report on the full investigation into Alton Sterling's death. The officers told Sterling to put his hands on the hood of a auto and struggled with him when he didn't comply, the Justice Department said.
"The Louisiana Department of Justice can not proceed with a prosecution of either Officer Lake or Officer Salamoni".
"We are confident in our ability to fairly and ethically review law enforcement use of force cases in Sacramento County".
Baton Rouge Police Chief Murphy Paul says he intends to release body camera and surveillance video of the fatal shooting of a black man after he concludes the disciplinary process for the two white officers involved.
In June 2017, Sterling's family filed a wrongful death lawsuit against the city government and police, alleging a history of excessive-force incidents and racism toward African-Americans.
