A welfare check at a Cherokee County home over the weekend ended with a man dead and a deputy hospitalized, officials say.

After the shooting, deputies say they found the body of the man's mother inside the home, who appeared to have been dead for a while.

According to the Cherokee County Sheriff's Office, deputies were called to the home on Whisperwood Trail in Acworth on Saturday evening for a welfare check.

At the home, officials say the deputies encountered 26-year-old Andre Alvear, who they say was armed. While details about the incident remain limited, the sheriff's office said its deputies shot and killed Alvear outside the residence.

One deputy was taken to Wellstar Kennestone Hospital with injuries. He has since been released.

During their investigation, officials say deputies detected the "odor of decay" coming from the home and found the body of who they believe was 61-year-old Luisa Petera Alvear, Andre's mother.

"Due to the advanced stage of decomposition, it is unknown how the female died," the sheriff's office said. The woman's body has been taken to the Georgia Bureau of Investigation Crime Lab for an autopsy.  

The GBI will investigate the deadly officer-involved shooting. The sheriff's office will lead the investigation into the woman's death.
