Police in Scottsdale, Arizona are dealing with four murders in the last four days, at least three of which appear to be linked, the Arizona Republic reports.
The tony Phoenix suburb has little violent crime, so a bunched grouping of murders is rare.
On Friday, two paralegals, Veleria Sharp and Laura Anderson, were shot and killed inside the law office where they worked. The third victim, Steven Pitt, is a forensic psychiatrist who worked on Phoenix's Baseline Killer case and the JonBenét Ramsey murder.
The fourth killing has not yet been tied to the other three, but is under investigation.
