Key Witness In Bobbi Kristina Brown’s Death

BOBBI KRISTINA BROWN'S distraught family members are conducting their own investigation into her death, The National ENQUIRER has learned exclusively.

As part of their secret probe, the family duped Bobbi Kristina’s close pal, 18-year-old Danyela Bradley.

She was invited to visit her while she lay in a coma at an Atlanta-area hospice.

But when she arrived, family members refused to allow her into the room – and instead grilled Danyela about what her boyfriend, 24-year-old Max Lomas, knew about the circumstances, according to Danyela’s sister, Lidiane Guedes.

“She didn’t even get a chance to see Krissi,” she told The ENQUIRER. Lomas, an accused drug dealer, found Bobbi Kristina unresponsive in a bathtub in her home on Jan. 31, and called 911.

Danyela was also in the home at the time.

According to Lidiane, Lomas could become a police informant and turn against Nick Gordon, his former friend and Bobbi Kristina’s live-in love, in the event a grand jury is convened in the case.
