A medical examiner confirmed Kim died from double pneumonia after coming down with a serious case of the flu.

Taking to Instagram, Al B. Sure!, real name Albert Brown, shared an emotional video of the moment he learned of Kim's "murder and how it ripped the soul from my physical body."

"I do know very clearly that #Kimberly didn't just check out all of a sudden over pneumonĂ­a. That's some bull sh**. Really? This is where I get in trouble," he wrote. He continued to refer to her death as murder, saying she was strong enough to fight pneumonia.

"We just celebrated our son @Quincy's new deal and Christmas special with @Netflix, and she was in fantastic health as well laughing seeing me and @Diddy's mutual exchange at the theater. I'm going to leave it here," he wrote.

He also tagged Kim's ex, Sean "Puffy" Combs, in the post. Kim and Sean shared twins, D'Lila and Jessie James, and son Cristian Combs.
