Help with labor law

I need help for someone who has mental disabilities and has been restricted from accessing their last paycheck. Attempts at communicating with the company have resulted in "we can't control that, e don't know how it works". It appears that this was retaliation and this person is being forced to wait a 2 week pay cycle. They ended their employment on Wednesday and payday was Friday. According to Colorado law their check was due the day they were terminated (or that following Friday) correct?

Please correct me if I'm wrong. I'm just trying to help and I'm incredibly ignorant to the laws.
