TMZ reports that two members of Nicki Minaj's tour crew, De'Von Pickett and Eric Parker, were both victims of a stabbing Wednesday morning in Philadelphia. Pickett was fatally injured, while Parker is in critical condition.

Pickett and Parker had flown into Philly to prepare for Minaj's forthcoming tour with her boyfriend, Meek Mill. NBC Philadelphia reports that an argument had occurred inside Che Bar & Grill, and the men involved ended up outside, where the stabbing occurred. The two victims were taken to the hospital, where Pickett died and Parker remains in treatment.

Minaj took to Instagram to express her regrets over the loss:

#Rp @myfabolouslife - these guys flew into Philly for my tour rehearsals 2 days ago and were both stabbed last night. #RIPDAYDAY condolences to your family. Unbelievable. Eric (on the right) is recovering. Another senseless act of violence that took the life of a great guy. So sad.

Vh1 also reports that Pickett was once a tour manager for K. Michelle, who shared this image on Instagram:

I'm in real shock. Woke up this morning to some awful news that you passed. My heart is broken. You managed my first tour ever the "Rebellious Soul Tour" You Were so supportive and excited about the growth of my career. When are we going to stop killing eachother? They don't even know they took away one of the best. You've guided so many careers. The road for many artist won't be the same. My heart hurts@daydaydoesdis Praying for your family and I know you are in a better place.

Philadelphia police are still in pursuit of a suspect, who reportedly drove off in a gray Buick LeSabre.
