FORT COLLINS, Colo. -- Colorado State University president Albert Yates (pictured, left) plans to meet with police, city leaders and student representatives today as the search continues for a suspect in six sex assaults since May.

The meeting is meant to help determine whether officials can boost community safety, CSU spokeswoman June Greist said.

Police have not identified a suspect in the attacks but have a fingerprint, a DNA sample and a black Quiksilver brand ball cap.

One witness reported seeing a faded light-blue 1980s four-door sedan leaving the area of the latest attack Aug. 23.

Investigators have received about 750 tips and 500 calls relating to the car and about 20 calls regarding the cap, police spokeswoman Rita Davis said Wednesday.

The Fort Collins Community Foundation has begun a reward fund to help in the effort. The nonprofit has pledges totaling about $10,000 from victims' families and area residents to reward to anyone who provides information that leads to an arrest and conviction, said foundation director Diane Hogerty.

The victims were a CSU student, a recent CSU graduate, two Front Range students, a single mother and a young working woman, police have said.

All were blindfolded by an attacker who entered their apartments through unlocked doors and windows while they were sleeping.
