Bobby Brown’s sister, Leolah Brown, has a lot to say about Nick Gordon and the current investigation regarding the incident that left Bobbi Kristina Brown in a coma. After finding out that Bobbi Kristina’s boyfriend, Nick Gordon, will be appearing on Dr. Phil’s TV show, she wrote a Facebook post alleging that Gordon is under investigation for attempted murder. “We have strong evidence of foul play. Until this investigation is completed by law enforcement, I would ask that you or anyone else not provide this individual a platform to spin this situation to his benefit,” Leolah wrote in the post which was personally addressed to Dr. Phil.

It should be noted that police have not confirmed that Gordon is under investigation for any crime, but they did reveal that they’re treating Bobbi Kristina’s case as a criminal investigation.

Gordon is set to appear on The Dr. Phil Show in a pre-taped episode. According to TMZ, Gordon believed that it was going to be an interview. However, it was actually an intervention organized by his mother and Dr. Phil. Also according to TMZ, Gordon was high on drugs and alcohol prior to the intervention and that he punched two of Dr. Phil’s staff on his way out. It was revealed that Gordon checked himself into rehab following the intervention.

In Leolah Brown’s Facebook post, she urged Gordon to step forward and share any information he has on what exactly happened to Bobbi Kristina. “If Nick Gordon does not have the courage to speak with my brother Bobby Brown and/or law enforcement about what happened the day my niece’s body was found in a bathtub, he does not deserve to have a platform to speak to anyone of your caliber until this investigation is concluded,” she wrote.

On January 21, Gordon and a friend found an unresponsive Bobbi Kristina in the bathtub at her home in Roswell, Georgia. She has been in a coma ever since.
