The killings in Arizona began Thursday afternoon, and they continued with alarming frequency.
First there was Steven E. Pitt, a forensic psychiatrist known for his work on high-profile cases like the JonBenet Ramsey investigation. He was shot outside his office in northeast Phoenix.
The next afternoon, Veleria Sharp, 48, a paralegal who had been shot, was seen stumbling down a street and begging for help. When the police followed a trail of blood back to the Scottsdale, Ariz., law firm where she worked, they found Laura Anderson, 49, another paralegal who had been shot. Both women died.
Just hours later, Marshall Levine’s girlfriend found him, a 72-year-old life coach and marriage counselor, dead of two gunshot wounds in his office. That brought the killings in this otherwise relaxed golf and spa hub to four.
By then, ballistic evidence had convinced the authorities that the first two shootings were related. And at about 9:30 p.m. Saturday, they got the most important of more than 100 tips — one that would lead them to Dwight Lamon Jones, a man who had a connection to all of the deceased through a bitter divorce proceeding several years ago.
By Monday morning they felt they had a solid case against Mr. Jones, 56, and they also knew where he was. The police arrived at an Extended Stay America hotel in Scottsdale and surreptitiously began to evacuate guests.
Mr. Jones figured out what was happening, and opened fire on the police. He did not strike any officers. Just after 8 a.m., he was discovered dead of a self-inflicted gunshot wound.
But those weren’t the only killings.
On Sunday, the police learned of the deaths of a man and a woman at a home in Fountain Hills, about 15 miles east of the other shootings. Though the police later said that they had not yet explicitly linked the deaths to Mr. Jones, they said they believe he was in the area sometime before the bodies were discovered. That brought the killings they believe he carried out to six in about 96 hours.
“In law enforcement, we don’t have the benefit of saying we were successful when lives are lost,” Sheriff Paul Penzone of Maricopa County said at a news conference, calling Mr. Jones’s actions “the worst of humanity.”
At the same news conference, Rich Slavin, an assistant chief with the Scottsdale Police Department, tied the first four deaths together. Mr. Jones, he said, had gone through “a divorce situation” eight or nine years ago, in which his now ex-wife, Connie Jones, had retained a lawyer at the firm where the paralegals were killed. As part of his divorce proceeding, Mr. Jones was also required to see Dr. Pitt; and his son was required to see a doctor who had used the office space Mr. Levine happened to be occupying the day Mr. Jones shot him.
“We started to see that Mr. Jones was visiting them in an effort to right some wrong,” Chief Slavin said, adding that the suspect had probably intended to kill Ms. Jones’s lawyer.
