Suspect in Murder of JonBenet Forensic Psychologist & 3 Other Killings Commits Suicide at Motel

PHOENIX, AZ — The suspect who has been linked to four recent murders in Arizona has killed himself after being surrounded by police at a motel, according to authorities.

SWAT teams swarmed the Extended Stay America hotel, ABC News reported. Several shots were reportedly heard inside the motel room.

Police reportedly gassed the room and sent a robot inside — and the machine was able to determine that the suspect had committed suicide.

Law-enforcement sources told ABC News the suspect is Dwight Lamon Jones, 56. Police say Jones has been linked to several different killings, all committed in a period of three days.

On Thursday, forensic psychiatrist Dr. Steven Pitt, who assisted in the JonBenét Ramseycase, was found dead outside of his office, near Scottsdale.

Witnesses told police they heard a loud argument followed with gunshots, Phoenix Police Sergeant Vince Lewis said Friday.

Pitt also consulted on nationally prominent cases including the Columbine High School massacre, the Jodi Arias trial, and the Phoenix serial killer known as the “Baseline Killer.”

On Friday, paralegals Veleria Sharp, 48, and Laura Anderson, 49, were fatally shot at a law office.

Police believe the paralegals’ deaths were related to the Pitt shooting.

Marshall Levine, a 72-year-old psychiatrist and hypnotherapist, was found shot inside a Scottsdale office building shortly after midnight Saturday.

Police described the suspect in Pitt’s murder as a bald man wearing a dark-colored hat with a short brim, and they released a sketch of the suspect.

Law-enforcement officials have since confirmed that the same gun was linked to all four murders.

The investigation continues.
