During a press conference streamed online on Tuesday evening (1 November), Mr Finner said the US hip hop artist, real name Kirsnick Khari Ball, was pronounced dead at the scene outside a Houston bowling alley earlier today.
He added that no arrests had been made yet but called on witnesses to come forward with information.
After detailing the tragic event, Mr Finner said: “Sometimes the hip hop community gets a bad name and I know, evident from this city and people who I have a personal relationship with, a lot of great people in our hip hop community and I respect them.
“But back to Takeoff. I got many calls from Houston and outside of Houston, and everyone spoke of what a great young man this is, how peaceful he is, what a great artist. And I’m calling up on everybody, hip hop artists in Houston and around the nation, we got to police ourselves.”
He continued: “It is so many talented individuals, men and women in that community, who again I love and I respect, and we all need to stand together and make sure nobody tears down that industry.”
He added that he does not want to speculate on whether Takeoff was the intended target but noted: “Based on what people say about him, he’s well respected, non-violent.
“I would not expect him to be involved but I do want to wait on the investigation but we have no reason to believe that he was involved in anything criminal at the time, just as people describe him as very peaceful, loving, great entertainer.”
During the press conference, Houston’s Mayor Sylvester Turner also offered his condolences to Takeoff’s family and friends and said he plans to continue the conversation about gun violence in the city.
“We have too many young men of colour that are being injured or killed and their future is cut off and family members and friends are left to mourn,” he said.
“This does not have to be our reality and it need not be our future. And so as it relates to this particular incident, what I would say to the people in this city and even beyond, we will solve this crime. Let us bring the person or persons to justice, and we will, and then we will continue to move to make our city a safer city.”
Police officers said they were called at approximately 2.34am local time (07:34 GMT) about a shooting outside Billiards and Bowling Alley in Houston where a private party of around 40 including Takeoff had been taking place.
Takeoff was found dead at the scene and two other individuals, a 23-year-old male and a 24-year-old female, were taken to the hospital with non-life-threatening injuries.
