The investigation into the home invasion robbery at Chris Brown’s San Fernando Valley home has stalled out because the singer is not cooperating with authorities, according to TMZ.

During the July robbery, Chris wasn’t home, but his aunt was held at gunpoint by 4 men and locked in a closet, while the house was ransacked.

The only lead the cops have is a fingerprint found at the scene. However, they haven’t yet found a match.
