The Florida judge overseeing the second-degree murder case involving neighborhood watch volunteer George Zimmerman says she may have a conflict of interest.

Circuit Judge Jessica Recksiedler said Friday during a hearing in Sanford, Fla., that her husband works with an attorney who referred Zimmerman to his current defense attorney, Mark O'Mara.

The lawyer who made that referral, Mark NeJame, is a well-known Orlando defense attorney who is serving as a CNN commentator on the case.

The judge asked O'Mara and prosecutors to file motions with their views on the possible conflict.

Prosecutors say Zimmerman fatally shot Martin in the chest during a confrontation on Feb. 26.

Zimmerman says he shot Martin in self-defense and has pleaded not guilty.

The lack of an arrest for more than 40 days led to protests nationwide.
