Mimi Argo-Laney, a community advocate who was Gov. Brian Kemp’s sister-in-law, has died. She was 61.

An obituary posted by the Williams Funeral Home and Crematory doesn’t list a cause for Laney’s death on Tuesday, but a person with direct knowledge who wasn’t authorized to speak publicly said she died of coronavirus-related complications.

Laney grew up in Athens and later moved to metro Atlanta. She was a founding member of the Spectrum Autism Support Group and a longtime member of Snellville Christian Church.

The obituary said she moved to Milledgeville last year.

Laney is one of two sisters of Georgia first lady Marty Kemp. She is survived by her husband, Russ Laney; sons Charles Laney Jr. and Robert Laney; and her mother, Jean Alderson Argo.

“Mimi’s passing leaves our entire family heartbroken,” the Kemp family said in a statement. “We ask for prayers for Russ, their two sons and everyone blessed to know and love her.”

A celebration of life will be held Sept. 18 in Snellville. In lieu of flowers, expressions of sympathy may be made to the Spectrum Autism Support Group.
