A special grand jury has indicted a Norfolk police officer for voluntary manslaughter in the shooting death of a mentally ill man.

The grand jury returned its indictment Thursday charging Michael Carlton Edington Jr. in the 2014 death of 35-year-old David Latham.

Police have said Latham was shot after he threatened the officer with a knife. The shooting occurred on June 6, 2014, at Latham's home.

Latham's mother, Audrey Latham, has said that her son had schizophrenia and had recently stopped taking his medication. She also has said police came to the family's home in the past to help her son obtain psychiatric care.

Norfolk Police Chief Michael Goldsmith said in a statement that he urges the public not to rush to judgment and exercise patience while the case proceeds.
