A man has been charged with first-degree murder related to the fatal stabbing of his estranged wife at a Meijer gas station in Macomb County, Michigan. 

The incident happened Sunday. Authorities said the woman, 23-year-old Stella Davis, died at a hospital as a result of her injuries during the altercation on Hall Road. 

Sydney Emmanuel Davis Jr., 25, of Utica, has now been charged with first-degree premeditated murder, Macomb County Prosecutor Peter J. Lucido said. Davis was his estranged wife, prosecutors said. Sydney Davis was arraigned Wednesday at the 41-A District Court in Shelby Township. If convicted, he faces life without the possibility of parole. 

Authorities say Sydney Davis left the scene and was found later in Armada Township with a severe laceration on his hand. He was treated at a hospital for that injury. 

Prosecutors say a child, whom the two are parents of, was in Stella Davis' car at the gas station to arrange for a custody exchange. The child is now in the care of another relative. 

"She just thought he wanted to see his son, and loving her son very much, she did not want to keep him away from the father," said Saif Mahmoud, the victim's brother. "She always thought about her son over herself, and it led to this.

"She's been to the police station many times, complaining about abuse and other things of that sort, and it was not taken seriously. She was pushed away by police officers because they said there isn't substantial evidence for her to at least create a police report. 

Sydney Davis is back in court on Oct. 7 for a probable cause conference. A preliminary examination is scheduled for Oct. 14.
