Almost two months after English professor Bill Feltt was attacked by a group of unknown men, police have received only one lead, which is turning colder as time goes on.

Adam Due, chief public safety officer for the University Police Department, said police are continuing to follow a tip about a group of men visiting campus Aug. 27, the night Feltt was beaten outside the Martin Luther King Jr. University Union.

University police have identified the men, but have met resistance when trying to speak with some of the visitors.

Police want to speak with several people from the group who live in Champaign, but the possible suspects have not been cooperative, forcing police to find different avenues to gain information.

Due did not say how police planned to contact the uncooperative visitors.

The men are the only possible suspects in the case, and Due said police have received no new leads despite a $2,500 reward offered by the Judicial Affairs Office. Police hoped the reward would bring people who knew the attackers or who involved in the assault forward.

Police were hoping Feltt would be able to identify some of his attackers in photos after he returned to work Sept. 23, but after looking through about 20 photographs, no one looked familiar.

Feltt described his attackers as six to eight men in their mid 20s. He said he believed at least some of the men did not attend Eastern.

The men attacked Feltt at 1:50 a.m. on Aug. 27 as he was leaving the Gregg Triad 24-hour computer lab.

Feltt was hospitalized at Sarah Bush Lincoln Health Center in Mattoon and Good Samaritan Hospital in Vinceness, Ind. for a brain hemorrhage, a skull fracture and a sinus infection. He was released from Good Samaritan Hospital on Sept. 12 and returned to teach Sept. 23.

He has ongoing dental work due to his injuries and a benefit fund has been set up at First Mid-Illinois Bank and Trust to assist him with medical bills.
