The female victim stabbed repeatedly to her neck area during a random assault at a bus stop within Birmingham has passed away, authorities verified.
The deceased woman, who was 34, was targeted on Smallbrook Queensway street, just outside the Bullring shopping centre, shortly before 21:00 GMT on Friday, according to police statements.
Djeison Rafael, 21, appeared before Birmingham Magistrates Court on Monday, facing charges for the violent incident.
He was previously accused with attempted murder but following the victim's passing the charge has been updated to murder.
The force said police personnel will remain around the city centre through Monday providing public assurance, while detectives assisted the victim's relatives.
Detectives are appealing for witnesses who may have seen Mr Rafael, identified as a Black British national, and is believed to have been wearing an all-grey tracksuit, black hat, trainers with a backpack.
The stabbing happened near the Bullring shopping centre, opposite primary access point to Birmingham New Street station.
Law enforcement confirmed they classified it as "unprovoked attack" and Det Insp James Nix said efforts continue to determine why it happened.
Shalini Doal, employed in the vicinity, recounted paramedic and police activity after completing her shift at about 22:00 Friday night.
She described the scene as extremely disorderly, adding that some of her colleagues heard a commotion at about 21:00.
"Many co-workers take public transport, take the tram... our security is compromised fundamentally, here in the city centre."
Another individual, twenty-five, resident of Stoke, mentioned visiting the city quite frequently visiting his partner who lives in the city, expressing concern about what had happened.
"It causes concern for my girlfriend," he said.
"She doesn't drive employed at major concert locations... and to think something completely unprovoked occurred, you know, it's horrible."
