    BOSTON - In court Tuesday, the man accused of driving under the influence and causing the crash that killed Mass State Trooper Thomas Clardy was seen in video checking out a medical marijuana dispensary shortly before the crash. 

    The video is from New England Treatment Access marijuana dispensary in Brookline. Prosecutors say it is shows the suspect buying marijuana right before the deadly crash. But the defense is painting a different picture.  

    David Njuguna was back in court for another day of testimony in his trial. Prosecutors showed surveillance video of Njuguna at the Brookline medical marijuana dispensary on multiple cameras.

    Jacob Quarrell was working the register that day.

    "He purchased four pre-rolled cigarettes," Quarrell testified. 

    At the dispensary, you see Njuguna walking out about an hour before the deadly crash.

    Njuguna is accused of driving while under the influence of marijuana when he crashed into the back of trooper Thomas Clardy's police cruiser. Clardy was killed. Investigators estimate Njuguna was going more than 80 miles per hour.  

    UMass Memorial Flight Paramedic Andrew Castellana testified in court about the extent of injuries. 

    "Probably a concussion. Probably internal injuries as well," he said. 

    A nurse who treated Njuguna testified how he talked about having a medical marijuana prescription, but not having used it recently. 

    Njuguna's attorney is arguing his client had a seizure and this was an awful accident. 

    Prosecutors listed about 34 potential witnesses. They are just under half-way through. The defense could call up to 5 witnesses.
