The Associated Press has left several messages with Cheryl Carpenter, Wafer's attorney, seeking comment.
Few details of the circumstances surrounding the shooting were made public before the news conference. Police say they believe McBride was involved in a car accident several blocks north in Detroit before the shooting. A toxicology report released Thursday showed she had alcohol and marijuana in her system.
Wafer is also charged with possession of a firearm during the attempted commission of a felony or commission of a felony.
Under a 2006 Michigan self-defense law, a homeowner has the right to use force during a break-in. Otherwise, a person must show that his or her life was in danger.
The shooting has prompted calls for a thorough investigation from civil rights groups that say race was a factor. McBride was an African-American, Wafer's race has not been revealed by authorities involved in the case.
The northeast section of Dearborn Heights is next to Detroit's far west side and is a diverse area that's home to white, black and Arab-American residents. The neighborhood where the shooting took place consists mostly of well-kept bungalows and small ranches, and is near a community college branch campus and a mosque.
