Three people were killed during a shooting at a rapper's party at an underground warehouse in Boyle Heights overnight. 

The shooting, which one LAPD detective is calling the "worst shooting incident of the year regarding fatalities" happened just after midnight in the 1400 block of S. Lorena Street near Grande Vista.

Witnesses told FOX 11's Travis Rice they were celebrating the birthday of rapper MoneySign Suede.

The rapper posted a statement on his Instagram account Sunday responding to the shooting.

"Just want to get on here real quick to send my condolences to what happened after this paid show last night," the rapper wrote. "I pray for all the people who were injured and died last night. My condolences and heart goes out to all the families of this hurt." MoneySign Suede added that he was arriving at home after the show when he was made aware of the shooting, and that he will stop shows for the time being.  

According to police, it appears there were multiple shooters. 

Randy Tyson, 25, and Daniel Dunbar, 27, both of Los Angeles, died at the scene, the Los Angeles County coroner's office reported.
