She later worked as morning news anchor and crime reporter at WCBD-TV in nearby Charleston, SC. While in Charleston, O'Dell's reports on the lenient police approach to DUI cases led to a State Law Enforcement Division investigation that resulted in state authorities re-issuing a more stringent directive regarding these cases.

In 1993, she joined NBC's WTVJ in Miami co-anchoring the 5:30pm news with Jackie Nespral. She left the station in 1995 to move to Las Vegas with her first husband.
