Spokane police Officer Jennifer DeRuwe briefed reporters today on the search for Sharlotte McGill's killer.

"It's really very, very fluid and so there's not an hour-by-hour update that I can provide," said DeRuwe, police spokeswoman. "I just have to trust that the community will trust me when saying we're doing our very best. It's the top priority for us."

DeRuwe reminded people to be aware of their surroundings and trust their instincts.

"I hate to think that people aren't comfortable to go walk on the trails, but I understand why they are," DeRuwe said.

Police continue to compile names of people who could possibly be suspects based on the McGill's description of her killer.

"This is really an ongoing, dynamic investigation," DeRuwe said. "So while names come in, names go out. people are excluded. people are included. You have patrol officers contacting people; detectives talking to people."

"As soon as I have information, I will push it out," she said.

McGill was fatally stabbed to death one week ago today as she walked her dog along the Spokane River in the 1800 block of East South Riverton.

She was able to describe her attacker before she died: a black man in his 30s with a bad eye. No other details were given.

Police said Wednesday that they believe a tip from the community will help them find the killer, but they're urging against racial profiling.
