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 in his room. 
 
 But those were not 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 they had not explicitly linked the deaths of the two — Mary Simmons, 70, and Bryon Thomas, 72 — to Mr. Jones, they said he may have been 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 Dr. 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.

 “She wasn’t present in that law firm that day,” Chief Slavin continued. “Unfortunately, two employees were.” 
 
 In a statement, Ms. Jones said she was “deeply saddened by the tragedy caused by my ex-husband,” who she called “a very emotionally disturbed person.” 
 
 She also said her husband, a retired Phoenix police detective, recognized the connection between the divorce and the three crime scenes and he notified the police Saturday night, around the time the police say they got the crucial tip. 
 
 “Personally, I have feared for my safety for the past nine years,” she said. “I cannot express the emotions I feel for the innocent families touched by this senseless violence.” 
 
 A Facebook page belonging to a “Dwight Jones” contains posts from May in which he leveled several accusations against Ms. Jones and called her a liar. The authorities said he had posted YouTube videos, which, as of Monday, appeared to have been removed. 
 
 Chief Slavin said Mr. Jones had been arrested around 2008 or 2009 on domestic violence charges alleging that he mistreated his wife and a child. He also said Mr. Jones had been residing at Extended Stay hotels for the past nine years. 
 
 Ms. Jones was far from the only person who was on edge over the past several days. The killings, which had not appeared to be random, worried those in the medical and legal professions and prompted the police to blanket Maricopa County with officers who provided security for people who may have been at risk. 
 
 “I personally fielded a lot of questions from those groups because they were concerned,” Sgt. Ben Hoster of the Scottsdale Police Department said. Among their inquiries, he said: “Should we go to work on Monday?” 
 
 At a breakfast restaurant just steps away from the hotel where Mr. Jones shot himself, Peter Verros, the restaurant’s owner, noted how uncommon violence was in the area. 
 
 “This is a suburb,” Mr. Verros, 40, said. “You’re not used to something like this — a four-, six-person murder spree in Scottsdale? Holy cow!” 
 
 When asked Monday about the killer’s motive, Chief Slavin said it was impossible to totally understand. 
 
 “Taking the lives of innocent people,” Phoenix Police Chief Jeri Williams said, “should never make any sense.” ||||| Police tape blocks off a home, as they investigate additional killings in the home, related to other Scottsdale, Ariz., victims killed over the past several days Monday, June 4, 2018, in Fountain Hills,...

 SCOTTSDALE, Ariz. (AP) — A hunch from a retired detective helped lead police to a man suspected of shooting six people to death in the Phoenix area, some of whom were connected to his divorce, authorities said after the assailant killed himself with officers closing in. 
 
 A round-the-clock investigation that began late last week led police Monday to an extended-stay hotel in suburban Scottsdale where 56-year-old Dwight Lamon Jones was staying. As officers approached, they heard gunfire and found his body. 
 
 Jones' victims included a well-known forensic psychiatrist who testified against him in court in 2010, two paralegals who worked for the law office that represented the suspect's wife, a marriage-and-divorce counselor who was apparently targeted in a case of mistaken identity and another man and woman who have not been identified, authorities said. 
 
 In an unexpected twist, the suspect's ex-wife, Connie Jones, said her current husband, a retired police detective, made the connection between her divorce and the crime scenes and notified police of his suspicion Saturday night. 
 
 Connie Jones said in a statement that her ex-husband was a "very emotionally disturbed person." 
 
 Jones was arrested in May 2009 at his family's Scottsdale home on a domestic violence charge after his wife said he backed her against a wall, hit her in the face and threatened to kill her, according to court records. The arrest was cited by his then-wife when she filed for divorce. 
 
 "Personally, I have feared for my safety for the past nine years. I cannot express the emotions I feel for the innocent families touched by this senseless violence," Connie Jones said. 
 
 "We started to see that Mr. Jones was visiting them in an effort to right some wrong based on what we could see," said Rich Slavin, assistant police chief in Scottsdale. 
 
 The slayings began Thursday with the fatal shooting of Dr. Steven Pitt, who, according to court records, had evaluated Jones and testified in 2010 that he had anxiety and mood disorders and symptoms of a paranoid personality. 
 
 Pitt said Jones did not conform to social norms and acted impulsively and aggressively. He lacked remorse and close friends and required excessive admiration, the records said. 
 
 The testimony was cited in the couple's November 2010 divorce, which granted Jones' wife sole custody of their now 21-year-old son. 
 
 "This is not a success story, but it's a story that has closure," Maricopa County Sheriff Paul Penzone said. 
 
 The 59-year-old psychiatrist was well known in his field and assisted in high-profile murder cases, including the JonBenet Ramsey mystery in Colorado and a notorious Phoenix serial killer investigation. 
 
 Paralegals Veleria Sharp, 48, and Laura Anderson, 49, worked at the law office that represented Jones' wife. Police believe Jones may have been targeting the attorney, but she was not present Friday when Jones went to the office in downtown Scottsdale. 
 
 Sharp was shot in the head but ran out of the office to get help before collapsing on the street, police said. She was pronounced dead at a hospital. 
 
 Counselor Marshall Levine, 72, appears to have been mistaken for someone else who once occupied the same office. At one time, the space was used by a counselor who saw Jones' son as part of the divorce. Levine, who took over the space, was not involved in the divorce case. 
 
 Police would not speculate why Jones tracked down people connected to his divorce so long after it happened. They say he had been living in extended-stay hotels for the past nine years. 
 
 Analysis of shell casings found at Pitts' office, the law firm and Levin's office confirmed that the victims were killed with the same gun, police said. 
 
 Jones' DNA was found on one of spent casings. And traffic cameras showed a vehicle fitting the description of Jones' gold Mercedes near the law firm 30 minutes before the double killing on Friday, police said. 
 
 The suspect has also been linked to two additional killings in Fountain Hills, an affluent suburb in the northeastern corner of metro Phoenix. The man and woman found dead inside the home have not been named publicly. 
 
 Jones, who was seen driving around Fountain Hills, was later seen dumping a .22-caliber gun stolen from the Fountain Hills home. 
 
 Some neighbors who were home on Monday afternoon stepped out to observe the police presence that remained on the street, which is usually a serene area. 
 
 "It's quiet around here," said landscaper Saul Ramirez, who stopped to take cellphone videos of the scene. 
 
 As police shared new details of the case, several hundred people crowded into a chapel at a mortuary in Scottsdale to honor Pitt with music, humorous stories and a Hebrew prayer of mourning. 
 
 He was remembered as a perfectionist in his work on major cases and a loving man who doted on his fiancee and family members. Phoenix police Lt. Bryan Chapman, who had become a close friend during their work on criminal cases, said Pitt volunteered countless hours to help investigate many lesser known crimes. 
 
 "He was the hardest working person I ever met," Chapman said.

– A suspect who killed himself as police closed in Monday is now believed to have killed six people in the Phoenix area, police say—and at least four of them were linked to his bitter 2010 divorce. Police believe 56-year-old Dwight Lamon Jones, who shot himself at a Scottsdale motel early Monday, killed all six people in around 96 hours starting early Thursday, the New York Times reports. Police say Jones started the spree when he killed prominent psychiatrist Steven Pitt, whom he'd been required to see as part of divorce proceedings. On Friday, he allegedly killed Veleria Sharp and Laura Anderson, two paralegals at the firm his wife used during the divorce. Hours later Jones allegedly killed Marshall Levine, a marriage counselor who used the same office as a counselor Jones' son saw during the divorce. Police believe Jones also killed Mary Simmons, 70, and Bryon Thomas, 72, in Fountain Hills, around 15 miles away from the other shootings, but their connection to him is still unclear. Jones left around 10 hours of YouTube video in which he outlines an alleged conspiracy to steal custody of his son, who's now 21 years old, the Arizona Republic reports. Ex-wife Connie Jones says Jones was a "very emotionally disturbed person" and she divorced him after he hit her and threatened to kill her. She was granted sole custody of their son. The AP reports that Jones says her new husband, a retired police detective, was the one who made the connection between the divorce and the shootings and told police of his suspicions.
