'Missed Leads' (Major problems in investigation of missing DA Ray Gricar-DA involved in PSU case)

BELLEFONTE — One year after former Centre County District Attorney Ray Gricar seemed to step off the face of the planet, a review of the police investigation has uncovered new details that indicate key elements may have been missed.
<snip>
Some startling revelations emerged:u An assistant district attorney is certain she saw Gricar in Bellefonte at 3 p.m. on Friday, April 15, 2005, the day he vanished. It was reported to police but dismissed as not fitting the timeline police had established for Gricar.u

Police admit they are not monitoring Gricar's checking and savings accounts for strange activity, which experts called a serious mistake.

Two close and longtime friends of the missing district attorney -- Ed Walker and Assistant District Attorney Steve Sloane, who is perhaps Gricar's best friend -- say they were never interviewed by Bellefonte police Officer Darrel Zaccagni, the lead investigator in the case.
Zaccagni also never interviewed Gricar's co-workers in the courthouse or District Attorney's Office.

He was also acting strangely at work. At one point, a case was being discussed, and he mumbled that he wouldn't be there.
It's stranger than I thought.
He was a DA. Why was only one officer investigating the case, and why didn't the state step in?
For whatever reason, they didn't conduct a thorough investigation. Even the most basic procedures were ignored. You always talk to coworkers, close friends, and monitor bank accounts.
