The ex-wife of a man suspected of killing six people with varying degrees of connection to their divorce says she's deeply saddened by the slayings.

Police suspect 56-year-old Dwight Lamon Jones in six killings since Thursday, including that of a forensic psychiatrist who testified that he had anxiety and mood disorders.

His ex-wife, Connie Jones, said in a statement Monday that her ex-husband was an emotionally disturbed person. She said she has feared for her safety for the past nine years.

Jones said her current husband, a retired police detective, made the connection between her divorce and the crime scenes and notified police.

Psychiatrist Steven Pitt evaluated Jones during divorce proceedings and testified against him in 2010.

Two other victims, paralegals Veleria Sharp and Laura Anderson, worked for the law firm that represented Jones' wife during the divorce.
