Kelley Cannon's estranged husband, James Cannon, 44, was found strangled to death on June 23 at his home in Green Hills.

Police said they arrested Kelley Cannon without incident on Thursday at her mother's home in west Nashville around 9 a.m. Evidence collected at James Cannon's home implicates her in the killing, police said.

Metro police spokesman Don Aaron wouldn't elaborate about the specific evidence that they said connects Kelley Cannon to the case.

A court hearing regarding the custody of Kelley Cannon's three children was postponed Thursday and rescheduled for later in July.

The children, who are 9 years old, 7 years old and 18 months old, are currently living with James Cannon's sister.

A civil attorney for Kelley Cannon said she has not seen her children since the day that her husband was found dead.

According to a police search warrant for her apartment, Cannon told detectives she had talked with her husband the night before his body was discovered.

She said she went to his residence on Bowling Avenue between 10 p.m. and midnight because she was concerned for her children's safety.

She said that when she arrived, she found the back door slightly open and the lights on in some of the downstairs rooms. Then, she said, she woke her children up and took them to her apartment.

Investigators later took clothes, a pair of black jeans and a dress that she told them she was wearing the night of her husband's death. Police also took an empty carton of Virginia Slims cigarettes.

Investigators took a DNA sample from Kelley Cannon to compare against evidence found where James Cannon's body was found.

Police said the couple had a history of domestic abuse.

The attorney representing James Cannon's family said Thursday's charges bring a sense of relief.

"They knew that this day was probably going to come at some point, and right now the family is focused on what's best for those three children," said the attorney.

Kelley Cannon's bail is set at $500,000. She can't try posting the bond until her first court appearance, which will be in about a week.
