The Victim: Jocelyn Sandberg, 41, was stabbed to death April 26, 2002. She was found by two Colorado College maintenance workers about 4:20 a.m. on the sidewalk at Cache La Poudre Street and Cascade Avenue in front of Armstrong Hall. She was a frequent customer at Poor Richard's restaurant.

The Crime: Returning from a concert in Boulder, Sandberg, operations manager at the college radio station KRCC, and a friend were at Dale and Tejon streets about 2 a.m. when a man stepped in front of their vehicle. Sandberg, who was driving, got out and confronted the man. The friend told police she saw Sandberg knocked to the ground before the man walked away. Sandberg, the friend said, chased after the man on foot.

Two days after the murder, a witness who was riding his bicycle past the college told investigators he saw a woman walking side by side with another person near Cache La Poudre and Cascade. The two were gesturing and appeared to be arguing before separating, the man told police. One of them chased after the other and hit the person in the back, the witness said, striking again and again when the person turned to face him or her. The witness said he saw the person being hit fall to the ground. The witness said he attempted to chase after the attacker on his bicycle, but lost sight of the person. He did not check on the person who'd been attacked and did not call police.

The Investigation: No arrests have been made and no suspects named.
