The death of 25-year-old Freddie Gray while in police custody has been ruled a homicide, Baltimore's State's Attorney Marilyn Mosby said Friday.

Mosby also announced Friday that criminal charges will be filed for the young black man's death, according to The Washington Post. The news comes a day after Baltimore police turned over the results of their own probe into how Gray suffered a spinal cord injury while in custody April 12 and died in the hospital a week later.

Baltimore authorities said Gray was injured while inside the transport police vehicle after his arrest.

But the six officers involved in the incident, who remain suspended with pay, did not establish probable cause to arrest Gray in the first place, Mosby said. Officers pursued and arrested Gray in West Baltimore after he made eye contact with them and ran away.

Police "illegally arrested Mr. Gray," Mosby said, according to the newspaper. The prosecutor said she also met with Gray's family and told them justice will be sought. "I assured his family that no one is above the law and I would pursue justice on their behalf," Mosby said.

City authorities were preparing Friday for another wave of protests like the ones that broke out following Gray's death. A 10 p.m. to 5 a.m. curfew implemented this week is expected to stay in effect over the weekend, The Post reported.

But as Baltimore saw its third night straight without looting and riots, it seems locals just want a chance to make sense of the tragedy in a poverty-stricken city with problems that existed long before the uproar and media storm.

"The state has used all of its resources, and yet no one feels victory over the situation," Pastor Walter Thomas, of New Psalmist Baptist Church where hundreds gathered on Thursday, told the newspaper.

"People feel disenfranchised. They feel powerless and they feel hopeless. We have to bring them the resources for a different way to view life."
