Six homicides in the Scottsdale area of Arizona appear to be linked to the murder suspect’s divorce.

A prominent forensic psychiatrist who consulted on the JonBenet Ramsey murder investigation is among six people believed to have been killed by 56-year-old Dwight Lamon Jones.

As CrimeOnline previously reported, the suspect fatally shot himself Monday at an area hotel as law enforcement closed in on his location.

Updates in the case indicate police believe he was motivated by lingering hostilities from his divorce nearly eight years ago. He allegedly targeted individuals with some role in the breakup of his marriage for the four-day killing spree.

According to reports, Jones’ ex-wife received custody of the couple’s 13-year-old son.

Jones reportedly received a $100,000 payment, alimony totaling $6,000 per month for five years, and a Mercedes in the divorce. Police say he lived predominantly in hotels after his marriage dissolved.

Three of the victims played pivotal roles in the divorce, according to authorities, and include a psychologist who testified in court and two paralegals from the firm representing his ex-wife in the case.

A fourth victim is a marriage counselor police believe might not have been an intended target. Police did not immediately reveal what, if any, known role the remaining two victims played in the divorce.

Judge Susanna Pineda was among those involved in the divorce who were afforded extra security as police attempted to track down the suspect last week.

“I felt comfortable because I had law enforcement at my home, so I didn’t feel that I was going to be at risk with them here,” she said.

The divorce reportedly began to crumble after Jones’ arrest in 2009 on suspicion of domestic violence. That incident was followed by an involuntary commitment to mental hospitals, according to officials.

In subsequent years, he allegedly uploaded a string of videos in which he complained about his ex-wife and supposed unfair treatment by the court system.

While the divorce was finalized years ago, experts say killers often devote an extended period of time to planning their crimes, as reported by Fox News.

“Most mass killings in American history were planned over months and years,” said Northeastern University professor emeritus of sociology and criminology Jack Levin.
