What happened Tuesday?
» Detective Michael Boyd reconstructed the route of the police van carrying Freddie Gray by using surveillance footage and his own memory. He told Officer Caesar Goodson's attorney that he did not see any evidence that Goodson made abrupt stops, starts or turns while transporting Gray.
» Six witnesses — including Boyd — took the stand for the prosecution Tuesday. Crime lab technician Thomas Wisner, serologist Virginia Cates and DNA analyst Thomas Hebert were called to establish that Gray's blood was found in the back of the van.
» Stacey Lyles-Foster, the acting warden of the Central Booking and Intake Facility in Baltimore, testified that detainees brought to the facility by police van are given quick medical assessments, and rejected if medical personnel there do not believe the detainee would be able to "withstand" the 24-hour booking process before receiving care. She testified that 612 detainees were rejected in 2014 of 42,852 brought to the facility. In 2015, she said, 619 of 32,782 individuals were rejected. On cross examination, Lyles-Foster said Gray had been rejected at the facility for medical reasons in December 2014. She said medical personnel believed he was having a possible overdose.
» After the midday break, the defense was allowed to call two medical experts who questioned the autopsy finding that Gray's death was a homicide. Dr. Jonathan Arden, former medical examiner and current forensic pathology consultant, said he did not believe Gray was injured until the final leg of the van transport — after Goodson and other officers had checked on him multiple times. Dr. Joel Winer, a neurosurgery expert, testified that Gray's injury "isn't something that occurs through evolution," but would have been immediate — leaving Gray "floppy like a dish rag or a jellyfish" and unable to sit up, as Porter has testified he did at the fourth and fifth stops.
