The plot thickens? Bobbi Kristina Brown’s cousin Jerod Brown took to Facebook on Monday, March 9 and insinuated that Bobbi's aunt, Pat Houston, is responsible for her condition. Jerod also claims that Bobbi’s mom, Whitney Houston, was murdered.

“Auntie Whitney was murdered not drowned. That's a fact. Now the whole bathroom plot shows up again w/ Bobbi Kristina's situation. C'mon are you people that bold to perform this act again on my family. And the public believes whatever these people put in their faces, I mean it is convincing if you're not on the inside. However, I will let it be known Kristina has always had suspicion about Pat Houston. Soon evidence will be handed over to assist this investigation,” Jerod wrote on Facebook.

The post comes, however, after Bobbi’s dad Bobby Brown's lawyers warned that Jerod’s comments “must be disregarded.”

After Jerod posted several updates and even set up a vigil for the 22-year-old star, who has been in a coma since being found unresponsive in a bathtub on Jan. 31, Bobby's lawyers released a statement discounting the relative. 

"Jerod Brown aka Jerod Carter aka YF Kennedy, continues to makes statements and appear on television, however, he has not had any communication with Bobby Brown or the Houston family," a statement read to Us Weekly last month. "He must be disregarded. Please do not attend any 'meet and greet' organized by Jerod Brown as he is unable to provide access to Bobbi Kristina or information on her condition. This is a criminal investigation and we do not need this side show."

Currently under investigation is Bobbi’s boyfriend Nick Gordon, who recently checked himself into rehab following an intervention with Dr. Phil. Bobbi’s other aunt, Leolah Brown, took to Facebook over the weekend and wrote: "Nick Gordon is under investigation for the attempted murder of my niece. We have strong evidence of foul play.” 

Police previously confirmed to Us Weekly there is an ongoing investigation surrounding Bobbi's hospitalization. Prior to entering rehab, Gordon’s lawyers repeatedly told Us that he was complying with police and that he “remains in constant prayer for his companion and he hopes to be reunited with her soon.”
