Authorities said 44-year-old James Cannon's body was found in the closet of his house at 710 Bowling Avenue by a cleaning worker.

Cannon is a partner in a company called Medical Reimbursements of America, based in Franklin, Tenn.

"The body has no outward sign of physical trauma. However, we believe this death to be suspicious, and it is being investigated as a homicide," said Metro police spokesman Don Aaron.

Cannon sued his wife, Kelley, in February for a divorce. The Cannons have a documented history of domestic violence in their marriage. The couple have three children.

"He sued her for divorce in February of this year, and there was significant animosity between the two," Aaron said.

In May 2008, Kelley Cannon was accused of ramming her car into her husband's car and trying to take their children away from him. According to an affidavit, Kelley Cannon smelled of alcohol, ripped James Cannon’s shirt and bruised him.

In 2005, James Cannon called police during an argument he was having with his wife. According to an affidavit, Cannon was heard during a phone call pleading with his wife to put a knife down.

Kelley Cannon was set to go to court on that charge on July 1.

Police said they spoke to Kelley Cannon, and the couple's children were with her at that time. The children were placed in the custody of James Cannon's relatives.

James Cannon graduated from Birmingham's Samford Law School. He got his start working at Bart Durham's law firm in Nashville.

"We socialized. We went to some events together and had a good time together. He had a great sense of humor and everybody liked him," said Durham.

As of Monday night, no arrests had been made in the case.
