BALTIMORE (AP) - Before prosecutors rested their case, a Baltimore Police Department DNA expert testified that Freddie Gray's blood was found inside a police wagon on a bench, a wall and a seatbelt.
Gray was a 25-year-old black man who died a week after his neck was broken while he was being transported in handcuffs and shackles in the back of a police transport van.
Thomas Hebert testified Tuesday at the manslaughter trial of Officer William Porter. Hebert was the state's 15th witness.
He says samples from eight bloodstains contained Gray's DNA.
Porter is also black. Prosecutors say his failure to summon medical help or buckle Gray in with a seatbelt amounted to criminal negligence.
