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.

Psychiatrist Steven Pitt evaluated Dwight Lamon Jones during divorce proceedings and testified against him in September 2010. Court records also show that Pitt told a court that Jones had anxiety and mood disorders and features of a paranoid personality.

Pitt assisted in high-profile cases including the JonBenet Ramsey investigation in Colorado.

Paralegals Veleria Sharp and Laura Anderson were killed Friday and worked for the law firm that represented Jones' wife during the divorce.

Police also suspect Jones of killing Marshall Levine, a 72-year-old counselor and life coach, and a man and woman whose bodies were found in a suburban Phoenix home on Monday. They haven't been identified.

Police say a suspect in four Phoenix area homicides that happened in a three-day period killed himself as SWAT officers entered his room at an extended stay hotel.

Phoenix police Sgt. Vince Lewis says officers evacuated people near the suspect's room before they entered it early Monday morning.

Shots were fired as the SWAT team went into the suspect's room but Lewis says officers did not fire any shots.

The suspect was identified only as an adult male.

A fourth professional found fatally shot in a three-day span has been identified by Arizona detectives as a 72-year-old counselor and life coach, but authorities were not immediately linking his death to that of the other three.

On Thursday, Dr. Steven Pitt, a prominent forensic psychiatrist who assisted in high-profile murder cases including the JonBenet Ramsey mystery in Colorado, and a notorious Phoenix serial killer investigation, was found dead near Scottsdale. Witnesses reported hearing a loud argument and gunfire outside Pitt's office.

Police said the killings Friday of paralegals Veleria Sharp, 48, and Laura Anderson, 49, were related to the Pitt shooting, but were still trying to determine exactly what linked the three victims.
