DETROIT, MI -- Civil rights activist Rev. Al Sharpton addressed the killing of Renisha McBride in a brief statement Friday morning.

McBride, 19, of Detroit was shot to death early Saturday morning outside a Dearborn Heights home on Outer Drive, where her family believes she was seeking help after a car crash.

The Wayne County Prosecutor's office said it can't issue charges against the homeowner who shot her without more information from Dearborn Heights police.

The shooter told police he thought McBride was breaking into his home and that his shotgun fired accidentally.

Activists have been demanding an arrest in the case, which has sparked outrage and social media activity on a national level, reminiscent of the response to the 2012 Florida shooting of Trayvon Martin, a black teenager who was shot and killed by a neighborhood watch volunteer.

"We are in prayer for the family of Renisha Mcbride but we are also urgently calling for justice for the loss of this daughter, sister, and friend," said Sharpton in a statement issued by the Michigan Chapter of the National Action Network, which the reverend founded.

The group was planned to hold a press conference on the matter at a Detroit church at 11 a.m. Friday, just as McBride's funeral is scheduled to take place a few mile away on Detrot's west side.

"When these incidents happen often time investigators try to prove guilt or not guilty in the investigation, but action was taken that led to a murder," said Rev. Charles E. Williams II, head of NAN's Detroit chapter. "Whether guilty or not guilty, that should be for the jury and court to decide."
