Insect and Spider Identification: Brown Recluse??, 4 by GretchenSeitz

Hello Friends! I just moved into a new house in which the basement was full of boxes when I looked at the property. On my first night here, I turned the light on in the basement and saw a spider that I am 99.9% sure was a brown recluse. I live in Colorado and know they are not indigenous to this area, but have history with them from growing up in the Midwest. I found several webs in the basement behind baseboards and such, which is absolutely their M.O. Can any of you help me identify these one way or the other? Thank you!
