VIDEO: Bobby Brown Speaks Out About Daughter’s DeathAfter spending six months in a coma, Bobbi Kristina died at the age of 22 on July 26, 2015.

The aspiring singer, who was found face down and unresponsive in a bathtub that January, died from lobar pneumonia and a lack of oxygen, which resulted in brain damage.

According to a toxicology report later completed during her autopsy, Bobbi Kristina had a mix of alcohol and drugs in her system.

In the interview, Brown blames his daughter’s ‘brother/husband’ Nick Gordon for her demise and also seems to indicate Gordon in Houston’s death as well, stating:

?It?s not a mystery to me the same thing that happened to my daughter is what happened to Whitney,? Bobby tells Roberts during the candid interview, referring to his ex-wife?s uncannily similar February 2012 death.

?There is only one person around both occasions.?

While Bobby refused to say?Nick Gordon?s name during the interview, he states,

?He knows what happened. I don?t know what happened that night, but he does.?

For the record, Bobby, along with Bobbi Kristina?s conservator Bedelia Hargrove, has since filed a $10 million wrongful death suit against Gordon in which they accuse Bobbi Kristina’s controversial love interest of allegedly having abused Bobbi Kristina as well as injecting her with a toxic mixture of drugs that ultimately led to her death.

Gordon’s lawyer later released a counterstatement calling the claims “slanderous and meritless.”

Bobby?s full ?interview with Robin Roberts airs on ABC tonight (Tuesday, June 7) at 10 p.m. ET.
