A year after her daughter was found strangled to death in her northeast Colorado Springs apartment, Pam Lively waits for her daughter's killer to be brought to justice.

"It's been hell. I've had to find 365 reasons to get out of bed in the morning, to find any purpose," Lively, 55, said.

Angelina Sicola was a 20-year-old communications major at the University of Colorado at Colorado Springs who was working toward her second-degree black belt at U.S. Taekwondo Center, which she considered her second home.

Police found Sicola's body on May 2, 2013 in her apartment at 3807 Half Turn Road and immediately called the death "suspicious."

The investigation remains open, , but no arrests have been made, said Colorado Springs police spokeswoman Lt. Catherine Buckley.

"We are actively working the case and we'll take any kind of information that could help," Buckley said.

Lively said she knows detectives have worked incessantly to try to find her daughter's killer, but it has been difficult to be patient because very little information has been made public, even to family members.

"They can't let details get out in public because they have to figure out if someone is lying. But it's been really frustrating because police don't tell anyone anything," Lively said. "I know that they've interviewed people this week and last week, going back for second and third interviews. They have a lot of DNA and fingerprint evidence, too."

Sicola's mother pleaded for anyone who may have seen or heard anything on the day of her daughter's killing to tell police.

"I hope that Angie's killer is looking over their shoulder every minute, just waiting for the police to descend and arrest them," Lively said. "We want justice. To anybody else who may know anything, please tell the police. The smallest detail could break the case."

Lively said her family and her friends have been her greatest source of support, even as the killing devastated everyone who knew and loved Sicola. Lively refuses to let any part of her daughter's memory fade.

"I would give anything to hear her giggle again," Lively said, her voice breaking. "She's amazing. I don't talk about her in the past-tense. She has the most beautiful brown eyes, she's got a kind heart and she's so intelligent."
