The murder of a forensic psychologist who weighed in on the JonBenet Ramsey and Columbine cases is related to at least two other Arizona killings, reports the New York Times. Dr. Steven Pitt was gunned down Thursday outside his Phoenix office, and police are now saying that the murder of two paralegals a day later "is related to the shooting of Steven Pitt." Both women were shot in the head inside a law office; one was able to walk outside to a stopped bus in search of help, despite her injuries. She died later in the hospital. Police then "followed a blood trail" to the legal office, where they found another woman dead. The victims were identified as Veleria Sharp, 48, and Laura Anderson, 49. Meanwhile, the AP reports that police are investigating whether the fatal shooting of a man early Saturday at an office park that mainly houses therapists was also related. (More forensics stories.)
