(CNN)The assistant medical examiner who called Freddie Gray’s death a homicide testified Friday in the trial of the police officer who was driving the van in which the doctor determined Gray suffered his injuries.

Dr. Carol Allan stated “with a reasonable degree of medical certainty” that the fatal spinal cord injury that Gray suffered was distinctive, that it could only happen in a certain way and that it occurred while he was in the van.
Her testimony is key in the prosecution’s case against Baltimore Police Officer Caesar Goodson, who faces the most serious charges in a controversial case that sparked days of unrest in Baltimore and protests across the country after Gray was arrested and died in April last year.
    Allan said she based her opinion on her autopsy of Gray, interviews with witnesses and an examination of the van where she said Gray was placed face-down on the floor with feet shackled and his hand tied behind his back.
    Goodson’s lawyer, Amy Askew, prodded Allan with questions designed to suggest Allan had stretched her medical opinion to classify Gray’s death as a homicide.
    “Mr. Gray’s death was while he was in custody,” said Allan, who testified she has performed 5,100 autopsies since being employed by the Maryland medical examiner’s office in 2003. “This is not an accident.”
    Prosecutors contend Goodson took the unbelted Gray on a “rough ride” — which was described as punitive measure police used against unruly subjects.
    They contend Goodson drove so radically that he blew through a stop sign and veered into another lane of traffic because of the speed he was traveling.
    Allan testified about a picture showing the injuries to Gray’s spinal cord, pointed out where the spinal cord was pinched and reiterated that the cause of death was a neck injury consistent with a homicide.
    Goodson is the third of six officers tried in the case.
    On Monday, the officer elected for a bench trial, meaning his fate will be decided by the same judge who acquitted a Baltimore officer last month on charges related to Gray’s controversial death last year.

    In December, a mistrial was declared in the case of William Porter, the first officer to go on trial in the in connection with Gray’s arrest and death. He is scheduled to be retried in September.
    Three other officers have yet to stand trial — Officer Garrett Miller, Lt. Brian Rice and Sgt. Alicia White.
    Rice’s trial will start July 5, Miller’s on July 27 and White’s on October 13.
    Goodson’s trial continues Monday.
