Judge acquits police driver of all charges in Freddie Gray death that sparked Baltimore riots

Six officers were charged in Gray's death, but only Officer Caesar Goodson was accused of murder.

Gray was fatally injured after officers bound his hands and feet and Goodson left him unprotected by a seat belt that prosecutors say would have kept him from slamming into the van's metal walls.

Baltimore Circuit Judge Barry Williams delivered his verdict after hearing five days of evidence in the non-jury trial. He also found Goodson not guilty of manslaughter, assault, misconduct in office, and reckless endangerment.

Williams ruled that the state failed to show that Goodson knew he had cause harm to Gray by leaving him unbuckled, or that Goodson was aware that Gray was injured and intentionally failed to call a medic.

"The state failed to prove the defendant knew or should have known that Mr Gray needed medical care," the judge said.

"Unlike in a shooting or a stabbing, or a car accident, this injury manifests itself internally," judge Williams said, citing conflicting evidence from medical experts.

He continued: "If the doctors weren't clear, how would a person without medical training know?"

The judge also said the state failed to prove that Goodson gave Gray a "rough ride".

"The state had a duty to show the defendant corruptly failed in his duty, not just that he made a mistake," the judge said.

Protests and rioting after Gray's death on April 19, 2015, set the city on fire, forcing Maryland to bring in the National Guard. The unrest forced the city's mayor to abandon her re-election campaign, and the Department of Justice opened an investigation into allegations of widespread police abuse.

Prosecutors said Goodson was criminally negligent when he failed to buckle Gray into a seatbelt or call for medical aid after Gray indicated that he wanted to go to a hospital. But Goodson would not talk to investigators or take the stand at trial, leaving the state with slim evidence of intent to harm.

The acquittal of Goodson, 46, is perhaps the most significant blow to State Attorney Marilyn Mosby's efforts to hold police accountable for Gray's death.

Last month, the same judge acquitted Officer Edward Nero of misdemeanor charges, and in December, he declared a mistrial after a jury failed to agree on manslaughter and other charges against Officer William Porter.

Porter faces a retrial in September, and three other officers have yet to be tried.

Gray was arrested on April 12 after running from an officer on bike patrol outside a public housing project not far from the Western District station house. A neighbour's video showed him handcuffed behind his back and hoisted into Goodson's van.

The van made a total of six stops that day, and Gray was unresponsive on arrival at the station house 45 minutes later. Prosecutors said Goodson was there throughout and checked on Gray during the third and fourth stops, so he should have known Gray was in distress. They said his failure to call a medic amounts to murder.

A prosecution expert testified that Gray could not possibly have broken his own neck. Prosecutors said the injury happened somewhere between the second and fourth stops, when Goodson and Porter lifted Gray off the floor.

Porter said in evidence that Gray was lethargic, but could breathe and speak, and did not seem injured. Prosecutors countered that the initial injury became critical as the trip continued.

Second-degree "depraved heart" murder, which carries up to 30 years in jail, would mean that Goodson was so negligent in his inaction that he cast aside any consideration for Gray's life.

During opening statements, prosecutors for the first time accused Goodson of giving Gray a "rough ride", intentionally leaving him unbuckled "to bounce him around in the back of the van".

But by closing arguments, they all but abandoned the theory, saying Goodson's failure to belt Gray in under the circumstances was sufficient to prove the intent necessary for a murder conviction.

"Officer Goodson never calls a medic, he never takes Freddie Gray to the hospital," said Deputy State's Attorney Jan Bledsoe. "He has breached his duty, and because of that breach Freddie Gray's life was shortened."

Chief Deputy State's Attorney Michael Schatzow said the failure to belt him in would still be a crime, although a difficult one to prosecute.

Goodson's lawyer Matthew Fraling fiercely rejected the allegations, telling the judge that Goodson was a "gentle" officer who did not buckle him in because Gray was exhibiting "violent and erratic" behaviour, citing witness evidence that he was making the wagon shake back and forth by kicking and flailing inside.

Fraling also said Gray said yes when Porter asked if he wanted to go to a hospital only because Gray hoped to avoid jail.

"They have failed to cobble together any type of case with reasonable inferences, let alone evidence," he said. "The mere fact that harm resulted doesn't mean the Officer Goodson's conduct is the cause of that harm."

Goodson's acquittal may impact the remaining cases. Officer Garrett Miller and Lieutenant Brian Rice are scheduled to stand trial in July on charges of assault, reckless endangerment and misconduct in office; Rice also faces a manslaughter charge.

All the officers but Goodson have filed defamation lawsuits against Baltimore State's Attorney Marilyn Mosby and Major Sam Cogen of the sheriff's office, who signed the charging documents.

The officers claim the criminal charges amounted to false and damaging information.
