State Rep. Mark Cohen (D-Philadelphia) sent a five-page letter to Inspector General Glenn A. Fine, whose office is handling the investigation into Luna’s mysterious death in December 2003. The letter requests that Fine and his office look into cases each man had prosecuted.

He said he was making the request because he thinks the Federal Bureau of Investigation (FBI) hasn’t seriously considered the possibility that Luna’s death was retribution connected to his work.

“I am writing to request a fresh, complete and independent investigation by your office, using all available resources at your disposal, into the cases prosecuted by these two public servants leading up to their disappearances,” Cohen states in the letter. “No stones should be left unturned.”

Luna was last seen at his office at the federal courthouse in Baltimore, the night before his body was found in a stream. He had been stabbed 36 times, according to police investigating the case. The 38-year-old left behind a wife and two children.

The FBI has said that a yearlong investigation turned up no evidence that Luna was with anyone between the time he left his Baltimore office late one evening and the discovery of his body six hours later.

Gricar disappeared on April 15, after he spoke on the phone with girlfriend and housemate Patty Fornicola at about 11:30 a.m. He told her he was taking a drive along state Route 192 in Brush Valley. The red-and-white Mini Cooper he’d been driving was found in Lewisburg one day later.

Cohen said he decided to write a letter after conversations with Bill Keisling, who wrote a book about Luna’s disappearance and has been following the investigation into Gricar’s.

“My brother served 24 years as an assistant district attorney,” Cohen said. “When a prosecutor is killed, it has an intimidating effect.”

Cohen said he’s disturbed at the lack of resolution in both cases, and thinks police should focus on the cases each man had prosecuted or were going to prosecute in searching for answers.

However, he said he did not know of any link between the two cases.

Cohen’s letter is under review, according to the Justice Department.
