Mario Willis’ new trial hearing in Detroit reaches day 6 as prosecutors challenge defense’s expert

The hearing in Detroit regarding Mario Willis' request for a new trial continued for the sixth day, with the prosecution challenging the testimony of defense expert Marc Fennell. Fennell argued that the original fire investigation, which led to Willis' 2008 conviction for a fatal fire, was flawed and should have been classified as "undetermined" rather than arson. Prosecutors rigorously questioned Fennell's conclusions, focusing on his methodology and the lack of photographic evidence. The proceedings, which began in December, have included testimony from key witnesses like Darian Dove, who claimed Willis paid him to start the fire, despite admitting to being a pathological liar.
