Text: Metropolitan Police Department Firearms Examiner Michael Mulderig took the stand as a firearms expert. He testified that on May 31 he began his examination of the 45 shell casings (caliber of 7.62 mm.) that were recovered outside the school. He concluded that they could have been fired from an assault rifle, such as an AK-47, and that the shell casings had been fired from two different rifles. Corroborating Ms. Route's testimony that Brisbon said to Wonson, I can't believe your gun jammed, he testified that one cartridge found at the murder scene was attempted to be fired but did not fire. James Sullivan, a fire investigation expert, testified that the Ford F-150 truck was set on fire with a lit ordinary combustible on the front passenger seat, which also corroborated Ms. Route's testimony.
