PHOENIX - A Phoenix man accused of fatally shooting his brother-in-law has been sentenced to 18 years in prison.
Maricopa County prosecutors say 33-year-old Steven Earl Lomax Jr. was sentenced Thursday.
He entered into a plea agreement and pleaded guilty to second-degree murder in the case.
Lomax was arrested in March for the death of 42-year-old Richard Swann.
Lomax's sister called police to report her husband had been shot multiple times.
Police say Lomax then took the phone, admitted shooting Swann and shot him again while speaking with the 911 operator.
Lomax surrendered when officers arrived. He lived in the same home as Swann and his sister.
According to police, Lomax later told a detective that shooting Swann was the only way to end Swann's physical and mental abuse of Lomax's sister.
