Maryland State's Attorney Marilyn Mosby announced on Friday that the six officers involved in the death of Freddie Gray will face criminal charges.

Gray, a 25-year-old black man, died of a severe and critical neck injury on April 19 exactly seven days after he was apprehended by Baltimore police. According to officials, Gray made eye contact with an officer and then fled the scene on the morning of Sunday, April 12. He was then chased by the officers, some of whom were patrolling the neighborhood on bike. Once they caught up to him, he was taken into custody for carrying a switchblade knife. However, an investigation determined that there are no laws barring the knife he was carrying, which means his arrest was illegal.

Cellphone footage of Gray's arrest revealed that his Gray's legs appeared to be limp as he was being dragged into a police van. Witnessed at the scene also said that Gray was screaming in pain and his legs did not seem to be functioning properly.

During a press conference at the downtown War Memorial on Friday morning, Mosby announced that Gray's death was ruled as a homicide, reports CNN. The state prosecutor also listed the charges filed against each of the six officers: Officer Caesar Goodson Jr. is facing second-degree murder; Officer William Porter, Lt. Brian Rice and Sgt. Alicia White are facing manslaughter; and Officer Edward and Officer Garrett Miller were charged with assault.

Other allegations include failure to find probable cause, illegal arrest, failure to seek or render medical aid, gross negligence and misconduct.

"The findings of our comprehensive, thorough and independent investigation coupled with the medical examiner's determination that Mr. Gray's death was a homicide ... has led us to believe that we have probable cause to file criminal charges," Mosby told reporters, according to CNN.

Officer Goodson, 45, faces the most severe punishment since he was driving the van in which Gray died. In addition to one count of second-degree depraved-heart murder, he has also been charged with involuntary manslaughter, second-degree assault, manslaughter by vehicle (gross negligence), manslaughter by vehicle (criminal negligence) and misconduct in office.

"Despite stopping for the purpose of checking on Mr. Gray's condition, at no point did he seek nor did he render any medical assistance for Mr. Gray," Mosby said of Goodson.

"Despite Mr. Gray's obvious and recognized need for medical assistance, Officer Goodson in a grossly negligent manner chose to respond ... with Gray still unsecured by a seat belt in the wagon, without rendering or summoning medical assistance."

In response to the charges, Michael Davey, an attorney for the Baltimore Fraternal Order of Police, spoke on behalf of the six officers, telling reporters that they did not injure or harm Gray.

"They are truly saddened by his death. These officers did nothing wrong," he said.

The Baltimore Sun reported that six officers posted bail and were released Friday night.
