Macca’s worker’s unhinged rant day before stabbing boss

A McDonald’s employee made a bloodcurdling Instagram video shortly before she allegedly murdered her manager.

Just days before a McDonald’s employee allegedly stabbed her manager to death, she posted an unhinged rant on Instagram about her “bully” boss.

Afeni Muhammad, 26, has been charged with murder after she allegedly stabbed her manager, Jennifer Harris, 39, at least 15 times at a McDonald’s in Detroit, Michigan, on Thursday.

Two days earlier, she took to social media to vent her anger over being sent home for her performance two days in a row.

“I got sent home early yesterday. I got sent home early today by the same person,” Muhammad said in the Instagram reel, posting from her account @officialrisenphoenix.

“I’m telling you, she’s a bully. This sh** isn’t funny … She needs to understand that just because she’s a mother and got children, that doesn’t mean she can come in the store disrespecting people, talking like everybody is beneath her. She has no respect and it isn’t funny at all.”

Muhammad’s alleged victim was a single mother of six who had been working at McDonald’s for 15 years.

“Like, seriously, man, I got sh** I need to take care of and she keeps sending me home early … she’s playing games,” Muhammad continued her foul-mouthed rant.

She then claimed her boss played “racial sh**”, spread negative energy and gossiped about people, before saying, “That sh**s gonna have to stop”.

“Then she tell me I am snapping on people. No, no, no, that’s false, I don’t snap on people. I don’t go doing that. No, I make peace. I’ve been creating peace,” she added.

After Ms Harris apparently sent Muhammad home again a second time, police say she told her boss, “I’ll be back,” before she went to her car and retrieved a kitchen knife.

When she re-entered the fast-food restaurant, witnesses say she was wearing a mask.

A drive-through customer witnessed the attack and fired a shot into the air to try to stop it, police reported.

Muhammad reportedly tried to escape but was stopped by the customer before her arrest by police.

The alleged murderer appeared in court on Friday and is held on a $25 million ($A38 million) bail.

She is charged with first-degree murder and unlawful possession of a dangerous weapon with intent.

The McDonald’s franchise owner stated: “We are deeply saddened by this tragic incident, and our hearts go out to the victim’s family and loved ones.

“Violence of any kind is unacceptable in my restaurants, and we are taking this matter extremely serious, as the safety and wellbeing of our employees and customers is our top priority. We are fully co-operating with law enforcement as they conduct their investigation, and the restaurant will remain closed until further notice.”

Muhammad’s lawyer said that she is a high school graduate currently taking online physical therapy classes. She is also an aspiring rapper.

Prosecutors said on Monday that she had prior convictions for stabbing someone in a different state.
