A 26-year-old woman has been arraigned on charges relating to the fatal stabbing of a McDonald's restaurant manager in Eastpointe, Michigan. 

Afeni Badu Muhammad, of Eastpointe. was in the 38th District Court Friday afternoon, before Judge Kathleen G. Galen. She is charged with first-degree premeditated murder and carrying a dangerous weapon with unlawful intent, according to the press release from the Macomb County Prosecutor's office. The murder charge carries a mandatory life in prison sentence without parole. The weapon charge is a five-year felony. 

Bond was set at $25 million, cash/surety only, the prosecutor reported. Muhammad's next court appearance will be a probable cause conference on July 23. A preliminary exam is scheduled for July 30. 

In the meantime, Muhammad is held at the Macomb County Jail. 

The victim, Jennifer Harris, 39, of Mt. Clemens, was stabbed multiple times during Thursday's assault. 

Harris had sent Muhammad home early on Thursday, but Muhammad later returned with a knife and entered through the employee entrance, the prosecutor's report said. She is then alleged to have stabbed the manager multiple times. 

A customer who saw the altercation was also lawfully carrying a concealed weapon and fired his weapon in an attempt to stop the assault. The suspect was then followed by the armed customer and held at gunpoint until Eastpointe police arrived. 

Harris had worked at the McDonald's restaurant for 15 years. She was the mother of six children. 

"This is an absolutely senseless and heartbreaking tragedy," Macomb County Prosecutor Peter J. Lucido said about the fatal assault. 

"We are deeply saddened by this tragic incident, and our hearts go out to the victim's family and loved ones," the restaurant's owner/operator Yusef Alcodray said in a statement.

Suspect appears to complain about work in Instagram posts

Video has surfaced, appearing to show Muhammad talking about problems at work on social media two days before the stabbing.

The July 8 videos appear to show Muhammad in her McDonald's uniform and complaining about her manager.

"I got sent home early yesterday. I got sent early today by the same person. I'm telling you, she's a bully," she said. "This isn't funny. She needs to understand that just because she's a mother and has children, it doesn't mean she can come into this store, disrespecting people and acting like everyone is beneath her. She has no respect."

Muhammad does not call anyone out by name, and doesn't detail plans for an attack. The footage does, however, make it clear that she was not happy with working conditions. She claims she is constantly being sent home and having her hours cut short.

"It isn't funny at all, and she keeps sending me home. I have (expletive) I need to take care of, and it's not funny. She is playing games," she said.

We got insight from former federal prosecutor Rick Convertino about how this video could play out in court proceedings.

"There's nothing she said in there that made it appear she was coming back to the McDonald's, but she certainly did. She's angry. She left. She gave a statement and she came back, which is evidence of premeditation or forethought. You need two elements to commit the crime.  One is actus reus, or the guilty act, and the intention. Both of these elements were met., Convertino said. It doesn't appear as though it's a very complicated case. Given the fact that there were witnesses."
