It was a bad day all around for Timothy Chapman, a one-time bounty hunter with Duane "Dog" Chapman.

His trial began yesterday morning in Circuit Court on charges of indecent exposure and terroristic threatening.

And in Family Court, Chapman's wife, Davinanatasha, filed divorce papers against him.

The tall, thin defendant, wearing his gray hair in a long ponytail, listened carefully to testimony about an incident on the evening of Jan. 3, 2008, in the Bank of Hawaii parking lot at Ala Moana Center.

Witness Kimberly Lum testified that she observed Chapman masturbating while he was sitting in the driver's seat of his pickup truck.

Ala Moana security guard Jason Wessel said that when he arrived on the scene and approached the truck, Chapman said, 'Oh, sh--," and threw himself into the back seat to begin pulling on a pair of pants.

Wessel said he did not see Chapman engaged in indecent behavior, but did see the defendant's bare left buttock when he moved to the back seat.

Defense attorney Brook Hart said Chapman committed no crime and was changing clothes after spilling orange juice on himself.

Wessel said after Chapman finished dressing himself, he ignored Wessel's request to step out of the vehicle, and instead climbed back in the driver's seat and drove quickly out of the parking lot, nearly hitting the security guard.

The nonjury trial continues before Circuit Judge Richard Perkins.
