News: Did Bobby Brown's daughter see this happening? New details emerge

Bobbi Kristina was allegedly obsessed with her mother being found dead in a bathtub and had been repeatedly talking about the upcoming third anniversary of her death, according to a source close to the family.

The daughter of late singer and entertainer Whitney Houston was found unresponsive, face down in a bathtub Saturday and taken to a hospital in the north Atlanta suburbs.

The news came as shock to most, but a Houston family insider told Entertainment at the Chicago Sun Times, that the 21-year-old had been constantly talking about her mother who died in a bathtub from an 'accidental' drug overdose almost exactly three years ago at the Beverly Hilton Hotel.

'She was seemingly obsessed by it - strangely more so than last year or the year before,' they said.

'She talked more about that anniversary, than her recent first wedding anniversary ,' to husband Nick Gordon. 

Another source told the newspaper that there were clear signs that Bobbi Kristina was struggling.  

More details have emerged on the critical condition on Bobbi Kristina Brown.

Back at her home, police continued investigating for signs of foul play or drugs. 

"We don't leave any stone unturned," Lisa Holland of the Roswell Police Department said of the procedure. "So the police took a search warrant on the home. Before the warrant, initially when the police went into the home there were nothing there that indicated that anything out of the ordinary happened. There were no drugs out in the open."
