Ronald Rogers Jr. is charged with two counts, including a felony murder charge that carries a maximum penalty of life in prison. Bail was set at $1 million cash.
Authorities say that 46-year-old Rogers killed Elizabeth Rogers. The 40-year-old woman died of a gunshot wound to the head.
Police say the preliminary investigation indicated the pair were arguing Tuesday night when Elizabeth Rogers fired the gun at her husband and then shot herself when he tried to take the weapon away.
But investigators say the crime scene and autopsy revealed inconsistencies with the original report.
Ronald Rogers is scheduled to make his first court appearance at 8:30 a.m. Monday.
