As Catherine joined Brass, who was already talking with Rhonda Stone, she took in the woman's appearance. Rhonda Stone was mid to later thirties, blond, petite, and apparently wracked with grief.

"Mrs. Stone, can you think of anyone who would want to harm your husband?" Brass inquired.

"No, that's just it. I can't imagine anyone wanting to hurt Mike. He's always helping the neighbors out and people at work just love him." She replied numbly.

Catherine interrupted, "Mrs. Stone, I'm Catherine Willows from the Crime Lab."

Rhonda Stone acknowledge Catherine, "Ms. Willows."

"Just call me Catherine." Catherine smiled at her to try and put her at ease. "Mrs. Stone, did your husband usually take the bus?"

Rhonda Stone looked up at Catherine with tears beginning in the corners of her eyes. "No, that's just it. He never rode the bus. His car was in for it's 60,000 mile service and he thought he'd take the bus instead of renting a car like he usually would since he didn't have any client meetings today. If he'd just rented a car, or taken mine, he'd still be alive." With this, Rhonda Stone put her head onto her arms on the table in front of her and broke into sobs.

Brass and Catherine exchanged glances and Brass nodded. Catherine placed a comforting hand on Rhonda Stone's shoulder. "Mrs. Stone, Detective Brass here is going to take you home now. If you can think of anything, I mean anything, please give me a call."

"Thank you, Catherine." She replied looking up finally through tear stained eyes. "I just don't know how we'll go on. Our kids.Mike and the kids are my whole life."

Brass escorted Rhonda Stone out of the interview room. Catherine mulled over the short interaction she'd just had with Rhonda Stone. She appeared to be sincere, and she was convinced that no one would harm her husband. Catherine knew they needed to dig deeper, to see what the evidence would tell them. She got up from her chair and proceeded out of the room and down the hall to fill Grissom in on her interview with Rhonda Stone.
