The psychiatrist has been involved in some high-profile murder investigations, and it is speculated that this might have something to do with his work.
Steven Pitt, a forensic psychiatrist in Phoenix, Arizona, was shot outside his office on Thursday, May 31 in broad daylight. At least two other victims are believed to be related to his shooting.
As reported by The Washington Post, witnesses nearby Pitt's office heard a loud argument on the streets before gunfire sounded off.
Just the day after Pitt's murder, two paralegals were shot inside the family law firm where they worked, about 10 miles away from Pitt's office.
Hours later, a psychologist was found shot dead in his office.
The four deaths raised questions to investigators whether or not Pitt was murdered because of his job, for which he studies the minds of criminals.
Sgt. Ben Hoster, a spokesman for the Scottsdale Police Department has stated that he believes the deaths of the two paralegals are connected to Pitt's murder.
The two women, Veleria Sharp, 48, and Laura Anderson, 49, were shot just after 2pm on Friday, June 1, at Burt, Feldman, Grenier family law firm, right across from government buildings.
One of the women, who was shot in the head, was able to make it out of the building and flag down a bus driver for help. Sadly, she passed away in hospital a few hours later.
While Hoster did not elaborate on why he feels the deaths are connected, or what the motive could have been, the police department released a sketch of the man they believe is responsible for killing Pitt.
Hoster has worked on cases such as that of the murder of JonBenét Ramsey, a child beauty-pageant star who was murdered inside her own home.
He also worked on a string of crimes in Phoenix in 2006 that were attributed to Mark Goudeau, also nicknamed the "Baseline Rapist" and "Baseline Killer."
Pitt also consulted on the Kobe Bryant rape case in Colorado, and worked on the Columbine High School shooting investigation.
The last shooting, that of 72-year-old psychologist Marshall Levine was reported shortly after midnight on Saturday, June 2. He was found by an acquaintance in his office with a gunshot wound.
It is unclear whether this fourth killing is related to the murders of Pitt, Sharp, and Anderson.
