Like the council, Pugh had vowed to thoroughly vet her choice for police commissioner after her previous pick, Darryl De Sousa, resigned after a few months on the job when he was charged with failing to file federal tax returns. Pugh hired a firm of private investigators to conduct its own review of Fitzgerald's background, including interviews of people who have worked with him. But details of those interviews have not been released to the public or council members and it's not known who the investigators met with.
