An argument between a man and a woman ultimately led to their deaths Saturday night in what police are calling a murder-suicide.

Metro police were called to the Whispering Oaks apartment complex off Harding Place in south Nashville around 9:45 p.m. after receiving reports of shots fired.

Upon their arrival, officers found 22-year-old Sherica Gray's body in the breezeway outside what was later determined to be her apartment.

Authorities said Boris Arapovic, 20, was found inside the apartment with self-inflicted gunshot wounds.

Arapovic was transported to Vanderbilt University Medical Center where he was pronounced dead.

Witnesses told police the two had been arguing before the shooting.

Neighbors told Nashville's News 2 the couple lived in the apartment for a few months and until Saturday, the couple seemed happy.

Susan French is the Outreach Service Director for the YWCA. She educates the public about domestic violence.

While she could not speak specifically about the Gray case, she did say it is common for neighbors, friends and family to be in the dark about an abusive relationship.

"It's really important for people to get involved and know the resources out there," she said. "Even if they do not feel like they are a victim of domestic violence themselves, they need to know the resources so they can pass it along to someone else."

Tennessee ranks fifth in the nation for women murdered by men. More than 90 percent of the women knew their killer.

"What we know about domestic violence is that it will start out with the verbal abuse, the mental abuse and some controlling behaviors like not allowing someone to have access to their friends or family members," she said. "Typically when the physical abuse starts the emotional abuse and the other abuse has been going on a while."

The YWCA has a 24-hour crisis line that is answered by trained counselors.
