Transcript for Pathologist Testifies 'Porch Shooting' Victim Had Concussion
With the boots. High-profile trial of a Michigan man charged with murdering an unarmed teen on his front porch. The prosecution has rested. Now Theodore wafer and his defense team are trying to convince the jury that the shooting was not a crime. ABC's Alex Perez has the story. Reporter: Theodore wafer's defense attorneys slamming investigators on the witness stand Wednesday accusing authorities of compromising evidence after wafer shot and killed 19-year-old renisha Mcbride. Don't you agree that it would have been best that night to call the experts in and have them process it? It wasn't a whodunit. We had Mr. Wafer admitting or saying that it was an accident. Reporter: Defense attorneys argue wafer intentionally fired his 12 gauge shotgun in self-defense when Mcbride ended up on his front porch intoxicated and backing on his door in the middle of the night last November. At the center of this case was Mcbride threatening wafer? It appears the distance between the end of the barrel and the decedent was less than three feet. Reporter: Prosecutors resting their case Wednesday. The defense calling a forensic pathologist who believes Mcbride had markings on his left hand the defense believes are injuries from trying to break into the home. The bleeding injury from the back of the hand is fresh, not dried and it had just happened. Reporter: Wafer's defense attorney is speaking out. Will jurors know what he was thinking? I hope he can put themselves in his shoe and realize what terror somebody would experience at 4:30 in the morning when you think multiple people are breaking into your house. Reporter: Carpenter won't reveal whether wafer who pleaded not guilty plans to take the stand. For "Good morning America," Alex Perez, ABC news, Detroit.
