Gwinnett County Police have identified the man who they say shot and killed a member of his own family on Easter Sunday. 

It started off as a family get together but turned deadly when police responded to a home on Grove Lake Street in unincorporated Loganville around 4:15 Sunday afternoon.

By the time officers arrived, they say, Christopher Greer, 44, was dead. 

Sean Edwards-Tuggle, 26, shot and killed his stepfather, Christopher Grier. 

Police say they do know there was an argument between Edwards-Tuggle and Grier, but are still working to find out what led up to the shooting.
