Bobby Brown banned his family from visiting his daughter Bobbi Kristina Brown at the hospice out of fear one of them may be responsible for taking the deathbed photo now being shopped.

According to TMZ, security officials working at the facility recently informed Whitney Houston's family there is mounting evidence one of the Browns is responsible for taking the picture. Legal guardians entrusted with running Bobbi Kristina's estate, who include her father and Aunt Pat Houston, then made the decision to impose the ban.

Several media outlets have reported the culprit has already contacted a number of websites and magazines looking to make a deal for the photo. On Sunday, Bobby Brown told TMZ he is committed to tracking down the person responsible, whoever it may prove to be.

"You aint gon [sic] be able to pay people off on this one," Brown's sister Leolah said. "You will not do to my niece what you did to Whitney."

Bobbi Kristina has remained unresponsive ever since being found face down in the bathtub of the Georgia she shared with boyfriend Nick Gordon in late January. Family members recently made the painful decision to take her off her life-preserving medications so she can "die naturally."

Plans call for Bobbi Krisitina to be buried alongside her mother so the two can be together in "eternity." Whitney Houston died a little more than three years ago after she was found face down in the bathtub of a Beverly Hills hotel. Authorities later revealed she had drugs in her system at the time of her death.

TMZ previously reported investigators launched a criminal probe into the circumstances surrounding Bobbi Kristina's injuries after doctors discovered several other unexplained bruises on her body. Reportedly, the probe targets the 25-year-old Gordon as the primary suspect.
