Allegheny County District Attorney Stephen Zappala Jr. has released consultant reports recommending security upgrades in the wake of a shooting at the Western Psychiatric Institute and Clinic in March.
A spokesman for the University of Pittsburgh Medical Center didn't immediately comment on the findings by two private security consultants. They recommend $2.1 million worth of upgrades, including adding a command and operations center, a new security card access system for employees, video surveillance, panic buttons and emergency call stations.
One worker was killed and five others were wounded by mentally ill gunman John Shick before campus police fatally shot him on March 8.
Zappala has said he's still investigating whether anyone might be criminally liable for not preventing the shooting, but says UPMC officials have been cooperative and are planning $10 million in security upgrades.
