(CNN) — An autopsy revealed Jayland Walker, the unarmed man who was shot and killed by Akron, Ohio, police at the end of a high-speed chase, had 46 gunshot entrance wounds or graze injuries, Summit County Medical Examiner Dr. Lisa Kohler said Friday.

His death was due to blood loss from his internal injuries, and the cause of death was multiple gunshot wounds, Kohler said.

Tests revealed no evidence of drugs or alcohol in his system, she added.

Walker, a 25-year-old Black man, was shot as he fled police officers trying to stop him for an alleged traffic violation. He was remembered as soft-spoken, loving and kind at his funeral Wednesday.

Details of the case continue to emerge amid public scrutiny of how law enforcement personnel across the United States use force, especially against people of color. Walker was Black, while seven of the eight officers who fired on him are White and one is Black, the city has said. All were put on paid administrative leave, per department policy.

Kohler said the gunshot entrance wounds included:

• 15 on Walker’s torso, where he had internal injuries to his heart, lungs, liver, spleen, left kidney, intestines and multiple ribs.
• 17 on his pelvis and upper legs, where the right major artery going to the leg and the bladder were injured and the pelvis and both femurs were broken.
• 1 on his face, where he jaw broke.
• 8 on his arms and right hand.
• 5 on his knees, right lower leg and right foot.

Walker’s family and representatives were able to review the report prior to this announcement at a news conference, Kohler said.

A gunshot residue test was not performed on Walker, the medical examiner said. Akron police accused him of firing what appeared to be a gunshot out the window. A gun was found in his car later. Police said he was not armed when killed.

Gunshot residue testing can detect specific particles related to the discharge of a firearm “but the results of that testing is not conclusive as to whether the person did or did not fire a weapon,” Kohler said.

The FBI discontinued this testing in 2006. She said the office discontinued the collection of that sampling in 2016 and no longer purchases collection kits.

NAACP wants Justice Department investigation

Also in the case, the NAACP on Thursday urged the Department of Justice to investigate the shooting, calling it a “gruesome assassination” in a letter to Attorney General Merrick Garland.

“No one is above the law, including law enforcement. Those responsible for hunting him down and firing 90 bullets at him should be held accountable to the fullest extent of the law,” NAACP President and CEO Derrick Johnson said in the letter. “We are urging you and your Department of Justice to conduct a thorough investigation into the murder of Jayland Walker, and — if what we all saw with our own eyes is true — federally charge the officers responsible for his gruesome assassination.”

“It is time to hold law enforcement officials accountable for treating Black Americans by different standards,” Johnson added in the letter. “We pray that your department will launch this critical investigation in the quest for justice in this case.”

A Justice Department spokesperson said, “The US Attorney’s Office, the Justice Department’s Civil Rights Division, and the FBI Field Office in Akron, Ohio are closely monitoring and reviewing the circumstances surrounding the death of Jayland Walker. The FBI continues to coordinate with state and local partners to provide resources and specialized skills. If the evidence reveals potential violations of federal criminal statutes, the Justice Department will take appropriate action.”
