Speaking at her husband\'s arson trial, a California woman said she doubts he committed the crime -- despite his apology for it. Cami Nunes-Durst, who referred to herself as an overly trusting \"doormat\" during testimony in Sacramento County Court Wednesday, explained her husband, Robert Durst, did work in 2009 on the home of their neighbor, Chris Liu, in the Oak Park section of Sacramento, and after delays in the work was paid only half of what Durst and Liu had agreed to. Durst is accused of six felony charges, including arson. Prosecutors allege he opened a gas valve in Liu\'s home and lit a candle, causing an explosion that destroyed the house and severely burned four firefighters. The Sacramento Bee reported Thursday Durst told police, during questioning the night of the fire, he meant only to \"burn the roof up, burn the ceiling, and burn the carpet up,\" and he \"felt bad\" about the firefighters\' injuries, transcripts say. The day after Durst\'s arrest, his wife told a reporter she felt \"mad, sad, embarrassed, humiliated, disgusted,\" but at the trial Wednesday Nunes-Durst refused to believe the accusations. \"You don\'t want to believe your husband had anything to do with this, do you?\" Deputy District Attorney Rob Norgaard asked.
